The following `tip` changes can be tested by building VictoriaLogs from the latest commit of [VictoriaMetrics](https://github.com/VictoriaMetrics/VictoriaMetrics/) repository
Revert "removed unneeded ref shortcodes, updated VM changelog to use relative markdown links (#6691)" This reverts commit 2e9b1efeb9422c60a345c67ebbbcaa5f8d37469d. Reason for revert: relative links in docs are much harder to maintain in consistent state comparing to absolute links: - It is non-trivial to figure out the proper relative link path when creating and editing docs. - Relative links break after moving the doc files to another paths, and it is non-trivial to figure which links are broken after that. - The updated relative links do not work properly right now in the docs. For example, the https://docs.victoriametrics.com/victorialogs/quickstart.md#building-from-source-code link at https://docs.victoriametrics.com/victorialogs/changelog/ leads to 404 page. This is documented at https://docs.victoriametrics.com/#images-in-documentation .

## tip
vmui/logs: improve graph usability (#7025) ### Describe Your Changes - Show the time range in the tooltip when hovering over staircase graphs. - Use bolder lines for staircase graphs. - Increase the number of steps on the staircase graph to 100. - Reduce the maximum width of the tooltip to 1/3 of the screen. - Insert only the label name under the cursor into the query input field when `Ctrl`-clicking the line legend. See [this comment](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6545#issuecomment-2336805237). ### Checklist The following checks are **mandatory**: - [ ] My change adheres [VictoriaMetrics contributing guidelines](https://docs.victoriametrics.com/contributing/). --------- Co-authored-by: Aliaksandr Valialkin <valyala@victoriametrics.com>
2024-09-27 13:19:46 +02:00
* FEATURE: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): improved readability of staircase graphs and tooltip usability. See [this comment](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6545#issuecomment-2336805237).
* FEATURE: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): simplify query input by adding only the label name when `ctrl`+clicking the line legend. See [this comment](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6545#issuecomment-2336805237).
vmui: add functionality to preserve selected columns (#7037) ### Describe Your Changes 1) Changed table settings from a popup to a modal window to simplify future functionality additions. 2) Added functionality to save selected columns when data is modified or the page is reloaded. See #7016. <details> <summary>Example screenshots</summary> <img alt="demo-1" width="600" src="https://github.com/user-attachments/assets/a5d9a910-363c-4931-8b12-18ea8b3d97d8"/> </details> ### Checklist The following checks are **mandatory**: - [x] My change adheres [VictoriaMetrics contributing guidelines](https://docs.victoriametrics.com/contributing/). --------- Co-authored-by: Roman Khavronenko <roman@victoriametrics.com>
2024-09-27 11:52:01 +02:00
* FEATURE: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): keep selected columns in table view on page reloads. Before, selected columns were reset on each update. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7016).
lib/logstorage: support skipping _stream: prefix for stream filters '_stream:{...}' can be written as '{...}' This simplifies writing queries with stream filters, and makes them more familier to Loki users.
2024-09-27 12:05:40 +02:00
* FEATURE: allow skipping `_stream:` prefix in [stream filters](https://docs.victoriametrics.com/victorialogs/logsql/#stream-filter). This simplifies writing queries with stream filters. Now `{foo="bar"}` is the recommended format for stream filters over the `_stream:{foo="bar"}` format.
lib/logstorage: allow using `-` instead of `!` as a shorthand for `NOT` operator in LogsQL
2024-09-27 13:12:34 +02:00
* FEATURE: allow using `-` instead of `!` as `NOT` operator shorthand in [logical filters](https://docs.victoriametrics.com/victorialogs/logsql/#logical-filter). For example, `-info -warn` query is equivalent to `!info !warn`. This simplifies transition from other query languages with full-text search support, which usually use `-` as `NOT` operator.

docs/VictoriaLogs/CHANGELOG.md: cut v0.30.1-victorialogs release
2024-09-27 11:20:58 +02:00
## [v0.30.1](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v0.30.1-victorialogs)
Released at 2024-09-27
lib/logstorage: consistently sort stream contexts belonging to different streams by the minimum time seen in the matching logs This should simplify debugging of stream_context output, since it remains stable over repeated requests.
2024-09-27 11:15:43 +02:00
* BUGFIX: consistently return matching log streams sorted by time from [`stream_context` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#stream_context-pipe). Previously log streams could be returned in arbitrary order with every request. This could complicate using `stream_context` pipe.
lib/logstorage: allow using `-` instead of `!` as a shorthand for `NOT` operator in LogsQL
2024-09-27 13:12:34 +02:00
* BUGFIX: [`stream_context` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#stream_context-pipe): add missing `_msg="---"` delimiter between stream contexts belonging to different [log streams](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields). This should simplify investigating `stream_context` output for multiple matching log streams.

## [v0.30.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v0.30.0-victorialogs)
Released at 2024-09-27
vmui/logs: add auto refresh (#7038) ### Describe Your Changes Add auto refresh #7017 ![image](https://github.com/user-attachments/assets/20ed1102-d5e4-4d3f-9c24-7d298d93400a) ### Checklist The following checks are **mandatory**: - [ ] My change adheres [VictoriaMetrics contributing guidelines](https://docs.victoriametrics.com/contributing/). --------- Co-authored-by: Roman Khavronenko <roman@victoriametrics.com>
2024-09-19 11:11:16 +02:00
* FEATURE: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): add button for enabling auto refresh, similarly to VictoriaMetrics vmui. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7017).
feature: [victorialogs] drop logs without non-empty _msg field (#7056) ### Describe Your Changes VictoriaLogs allows logs without `_msg` field or `_msg` field is empty. This lead to incorrect search result. See: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6785 This pull request search for non-empty `_msg` field before log entry is added to `LogRows`. New counter `vl_rows_dropped_total{reason="msg_not_exist"}` is introduced. Example log output: ``` 2024-09-23T02:33:19.719Z warn app/vlinsert/insertutils/common_params.go:189 dropping log line without _msg field; [{@timestamp 2024-09-18T13:42:16.600000000Z} {Attributes.array.attribute ["many","values"]} {Attributes.boolean.attribute true} {Attributes.double.attribute 637.704} {Attributes.int.attribute 10} {Attributes.map.attribute.some.map.key some value} {Attributes.string.attribute some string} {Body Example ddddddddddlog record} {Resource.service.name my.service} {Scope.my.scope.attribute some scope attribute} {Scope.name my.library} {Scope.version 1.0.0} {SeverityNumber 10} {SeverityText Information} {SpanId eee19b7ec3c1b174} {TraceFlags 0} {TraceId 5b8efff798038103d269b633813fc60c}] ``` ### Checklist The following checks are **mandatory**: - [x] My change adheres [VictoriaMetrics contributing guidelines](https://docs.victoriametrics.com/contributing/). - [ ] Benchmark for potential performance loss. --------- Co-authored-by: Aliaksandr Valialkin <valyala@victoriametrics.com>
2024-09-26 09:35:28 +02:00
* FEATURE: drop logs without [`_msg`](https://docs.victoriametrics.com/victorialogs/keyconcepts/#message-field) field or with empty `_msg` field, since this field is required to be non-empty in [VictoriaLogs data model](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6785).
lib/logstorage: read timestamps column when it is really needed during query execution Previously timestamps column was read unconditionally on every query. This could significantly slow down queries, which do not need reading this column like in https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7070 .
2024-09-25 16:16:53 +02:00
* FEATURE: improve performance of analytical queries, which do not need reading the `_time` field. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7070).
lib/logstorage: add `blocks_count` pipe This pipe is useful for debugging purposes when the number of processed blocks must be calculated for the given query: <query> | blocks_count This helps detecting the root cause of query performance slowdown in cases like https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7070
2024-09-25 19:15:32 +02:00
* FEATURE: add [`blocks_count` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#blocks_count-pipe), which can be used for counting the number of matching blocks for the given query. For example, `_time:5m | blocks_count` returns the number of blocks with logs for the last 5 minutes. This pipe can be useful for debugging purposes.
app/vlinsert: support `_time` field without timezone information during data ingestion Use local timezone of the host server in this case. The timezone can be overridden with TZ environment variable if needed. While at it, allow using whitespace instead of T as a delimiter between data and time in the ingested _time field. For example, '2024-09-20 10:20:30' is now accepted during data ingestion. This is valid ISO8601 format, which is used by some log shippers, so it should be supported. This format is also known as SQL datetime format. Also assume local time zone when time without timezone information is passed to querying APIs. Previously such a time was parsed in UTC timezone. Add `Z` to the end of the time string if the old behaviour is preferred. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6721
2024-09-26 12:43:16 +02:00
* FEATURE: support [ingesting logs](https://docs.victoriametrics.com/victorialogs/data-ingestion/) with `_time` field, which doesn't contain timezone information. For example, `2024-09-20T10:20:30`. In this case the local timezone of the host where VictoriaLogs runs is used. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6721).
lib/logstorage: properly return surrounding logs outside the selected time range by stream_context pipe Previously only logs inside the selected time range could be returned by stream_context pipe. For example, the following query could return up to 10 surrounding logs only for the last 5 minutes, while most users expect this query should return up to 10 surrounding logs without restrictions on the time range. _time:5m panic | stream_context before 10 This enables the ability to implement stream context feature at VictoriaLogs web UI: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7063 . Reduce memory usage when returning stream context over big log streams with millions of entries. The new logic scans over all the log messages for the selected log stream, while keeping in memory only the given number of surrounding logs. Previously all the logs for the given log stream on the selected time range were loaded in memory before selecting the needed surrounding logs. This should help https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6730 . Reduce the scan performance for big log streams by fetching only the requested fields. For example, the following query should be executed much faster than before if logs contain many fields other than _stream, _msg and _time: panic | stream_context after 30 | fields _stream, _msg, _time
2024-09-26 16:52:55 +02:00
* FEATURE: reduce memory usage when [`stream_context` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#stream_context-pipe) is applied to [log streams](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) with big number of messages. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6730).

See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7028). The bug has been introduced in [v0.29.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v0.29.0-victorialogs).

* BUGFIX: properly return logs without [`_msg`](https://docs.victoriametrics.com/victorialogs/keyconcepts/#message-field) field when `*` query is passed to [`/select/logsql/query` endpoint](https://docs.victoriametrics.com/victorialogs/querying/#querying-logs) together with positive `limit` arg. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6785). Thanks to @jiekun for identifying the root cause of the issue.

See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6943) for details.
lib/logstorage: pre-calculate hashes from tokens used in bloom filter search Previously per-token hashes for per-block bloom filters were re-calculated on every scanned block. This could be slow when the number of tokens is big or when the number of blocks to scan is big. Pre-calculate hashes for bloom filters and then use them for searching in bloom filters. This improves performance by 2.5x for in(...) filters with many values to search inside `in()`.
2024-09-05 19:40:50 +02:00
* FEATURE: optimize [multi-exact queries](https://docs.victoriametrics.com/victorialogs/logsql/#multi-exact-filter) with many phrases to search. For example, `ip:in(path:="/foo/bar" | keep ip)` when there are many unique values for `ip` field among log entries with `/foo/bar` path.

follow-up after 1731c0eabfe0c69fb0fa9a3dec8b39d9546db30c * updates change log * adds VL-Debug http header * updates doc * extracts only the first value of http headers for VL-Stream-Fields and VL-Ignore-Fields. It makes behaviour the same as Query string args. And allows to easily configure client applications. Since most of the client collectors don't support multi value headers.

lib/logstorage: properly fix incorrect extraction of common tokens for `OR` filters at distinct log fields Previously (f1:foo OR f2:bar) was incorrectly returning `foo` token for `f1` and `bar` token for `f2`. These tokens were used for checking against bloom filter for every data block, so the data block, which didn't contain simultaneously `foo` token for `f1` field and `bar` token for `f2` field, was skipped. This was incorrect, since such a block may contain logs matching the original OR filter. The fix is to return common tokens from `OR`-delimted filters only if these tokens exist at EVERY such filter for the given field name. If some `OR`-delimited filter misses the given field name, then `OR`-delimited filters do not contain common tokens, which could be used for checking against bloom filter. While at it, add more tests covering various edge cases for filters delimited by AND and OR.

For example, `field1:foo OR field2:bar`. Previously logs matching these filters may be skipped during querying.

Released at 2024-07-10
Revert "removed unneeded ref shortcodes, updated VM changelog to use relative markdown links (#6691)" This reverts commit 2e9b1efeb9422c60a345c67ebbbcaa5f8d37469d. Reason for revert: relative links in docs are much harder to maintain in consistent state comparing to absolute links: - It is non-trivial to figure out the proper relative link path when creating and editing docs. - Relative links break after moving the doc files to another paths, and it is non-trivial to figure which links are broken after that. - The updated relative links do not work properly right now in the docs. For example, the https://docs.victoriametrics.com/victorialogs/quickstart.md#building-from-source-code link at https://docs.victoriametrics.com/victorialogs/changelog/ leads to 404 page.

* BUGFIX: properly JSON-encode strings with special chars in [HTTP querying API](https://docs.victoriametrics.com/victorialogs/querying/#http-api) responses. This fixes the `error decode response: invalid character 'x' in string escape code` error in [VictoriaLogs datasource for Grafana](https://github.com/VictoriaMetrics/victorialogs-datasource/). See [this issue](https://github.com/VictoriaMetrics/victorialogs-datasource/issues/24).

* BUGFIX: return the proper surrounding logs for [`stream_context` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#stream_context-pipe) when additional [pipes](https://docs.victoriametrics.com/victorialogs/logsql/#pipes) are put after the `stream_context` pipe. This has been broken in [v0.26.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v0.26.0-victorialogs).
lib/logstorage: properly search for the surrounding logs in `stream_context` pipe The set of log fields in the found logs may differ from the set of log fields present in the log stream. So compare only the log fields in the found logs when searching for the matching log entry in the log stream. While at it, return _stream field in the delimiter log entry, since this field is used by VictoriaLogs Web UI for grouping logs by log streams.

* FEATURE: add ability to return log position (aka rank) after sorting logs with [`sort` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#sort-pipe). This can be done by adding `rank as <fieldName>` to the end of `| sort ...` pipe. For example, `_time:5m | sort by (_time) rank as position` instructs storing position of every sorted log line into `position` [field name](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model).
* FEATURE: add delimiter log with `---` message between log chunks returned by [`stream_context` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#stream_context-pipe). This should simplify investigation of the returned logs.
* FEATURE: reduce memory usage when big number of context logs are requested from [`stream_context` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#stream_context-pipe).

This functionality may be useful for investigating stacktraces, panics or some correlated log messages. This functionality is similar to `grep -A` and `grep -B`.
* FEATURE: add ability to return top `N` `"fields"` groups from [`/select/logsql/hits` HTTP endpoint](https://docs.victoriametrics.com/victorialogs/querying/#querying-hits-stats), by specifying `fields_limit=N` query arg.

* FEATURE: [syslog data ingestion](https://docs.victoriametrics.com/victorialogs/data-ingestion/syslog/): parse [STRUCTURED-DATA](https://datatracker.ietf.org/doc/html/rfc5424#section-6.3) into `SD-ID.field1=value1`, `SD-ID.field2=value2`, ..., `SD-ID.fieldN=valueN` [log fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model). Previously the `STRUCTURED-DATA` was parsed into a single log field with the `SD-ID` name and `field1=value1 field2=value2 ... fieldN=valueN` value. This could complicate querying of such data.

Revert "removed unneeded ref shortcodes, updated VM changelog to use relative markdown links (#6691)" This reverts commit 2e9b1efeb9422c60a345c67ebbbcaa5f8d37469d. Reason for revert: relative links in docs are much harder to maintain in consistent state comparing to absolute links: - It is non-trivial to figure out the proper relative link path when creating and editing docs. - Relative links break after moving the doc files to another paths, and it is non-trivial to figure which links are broken after that. - The updated relative links do not work properly right now in the docs. For example, the https://docs.victoriametrics.com/victorialogs/quickstart.md#building-from-source-code link at https://docs.victoriametrics.com/victorialogs/changelog/ leads to 404 page.

* FEATURE: add `default` operator to [`math` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#math-pipe). It allows overriding `NaN` results with the given default value.
* FEATURE: add `exp()` and `ln()` functions to [`math` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#math-pipe).
* FEATURE: allow omitting result name in [`math` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#math-pipe) expresions. In this case the result name is automatically set to string representation of the corresponding math expression. For example, `_time:5m | math duration / 1000` is equivalent to `_time:5m | math (duration / 1000) as "duration / 1000"`.
* FEATURE: allow omitting result name in [`stats` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#stats-pipe). In this case the result name is automatically set to string representation of the corresponding [stats function expression](https://docs.victoriametrics.com/victorialogs/logsql/#stats-pipe-functions). For example, `_time:5m | count(*)` is valid [LogsQL query](https://docs.victoriametrics.com/victorialogs/logsql/) now. It is equivalent to `_time:5m | stats count(*) as "count(*)"`.

Released at 2024-05-29
Revert "removed unneeded ref shortcodes, updated VM changelog to use relative markdown links (#6691)" This reverts commit 2e9b1efeb9422c60a345c67ebbbcaa5f8d37469d. Reason for revert: relative links in docs are much harder to maintain in consistent state comparing to absolute links: - It is non-trivial to figure out the proper relative link path when creating and editing docs. - Relative links break after moving the doc files to another paths, and it is non-trivial to figure which links are broken after that. - The updated relative links do not work properly right now in the docs. For example, the https://docs.victoriametrics.com/victorialogs/quickstart.md#building-from-source-code link at https://docs.victoriametrics.com/victorialogs/changelog/ leads to 404 page. This is documented at https://docs.victoriametrics.com/#images-in-documentation .
2024-07-25 12:47:35 +02:00
* FEATURE: allow specifying fields, which must be packed into JSON in [`pack_json` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#pack_json-pipe) via `pack_json fields (field1, ..., fieldN)` syntax.

* FEATURE: add [`extract_regexp` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#extract_regexp-pipe) for extracting arbitrary substrings from [log fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model) with [RE2 regular expressions](https://github.com/google/re2/wiki/Syntax).
* FEATURE: add [`math` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#math-pipe) for mathematical calculations over [log fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model).
* FEATURE: add [`field_values` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#field_values-pipe), which returns unique values for the given [log field](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model).
* FEATURE: allow omitting `stats` prefix in [`stats` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#stats-pipe). For example, `_time:5m | count() rows` is a valid query now. It is equivalent to `_time:5m | stats count() as rows`.
* FEATURE: allow omitting `filter` prefix in [`filter` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#filter-pipe) if the filter doesn't clash with [pipe names](#https://docs.victoriametrics.com/victorialogs/logsql/#pipes). For example, `_time:5m | stats by (host) count() rows | rows:>1000` is a valid query now. It is equivalent to `_time:5m | stats by (host) count() rows | filter rows:>1000`.
* FEATURE: allow [`head` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#limit-pipe) without number. For example, `error | head`. In this case 10 first values are returned as `head` Unix command does by default.
* FEATURE: allow using [comparison filters](https://docs.victoriametrics.com/victorialogs/logsql/#range-comparison-filter) with strings. For example, `some_text_field:>="foo"` matches [log entries](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model) with `some_text_field` field values bigger or equal to `foo`.

Released at 2024-05-22
Revert "removed unneeded ref shortcodes, updated VM changelog to use relative markdown links (#6691)" This reverts commit 2e9b1efeb9422c60a345c67ebbbcaa5f8d37469d. Reason for revert: relative links in docs are much harder to maintain in consistent state comparing to absolute links: - It is non-trivial to figure out the proper relative link path when creating and editing docs. - Relative links break after moving the doc files to another paths, and it is non-trivial to figure which links are broken after that. - The updated relative links do not work properly right now in the docs. For example, the https://docs.victoriametrics.com/victorialogs/quickstart.md#building-from-source-code link at https://docs.victoriametrics.com/victorialogs/changelog/ leads to 404 page. This is documented at https://docs.victoriametrics.com/#images-in-documentation .

## [v0.8.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v0.8.0-victorialogs)
Released at 2024-05-20

2024-07-25 12:47:35 +02:00
* FEATURE: add ability to extract JSON fields from [log fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model). See [these docs](https://docs.victoriametrics.com/victorialogs/logsql/#unpack_json-pipe).
* FEATURE: add ability to extract [logfmt](https://brandur.org/logfmt) fields from [log fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model). See [these docs](https://docs.victoriametrics.com/victorialogs/logsql/#unpack_logfmt-pipe).
* FEATURE: add ability to extract arbitrary text from [log fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model) into the output fields. See [these docs](https://docs.victoriametrics.com/victorialogs/logsql/#extract-pipe).
* FEATURE: add ability to put arbitrary [queries](https://docs.victoriametrics.com/victorialogs/logsql/#query-syntax) inside [`in()` filter](https://docs.victoriametrics.com/victorialogs/logsql/#multi-exact-filter).
* FEATURE: add support for post-filtering of query results with [`filter` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#filter-pipe).
* FEATURE: allow applying individual [filters](https://docs.victoriametrics.com/victorialogs/logsql/#filters) per each [stats function](https://docs.victoriametrics.com/victorialogs/logsql/#stats-pipe-functions). See [these docs](https://docs.victoriametrics.com/victorialogs/logsql/#stats-with-additional-filters).
* FEATURE: allow passing string values to [`min`](https://docs.victoriametrics.com/victorialogs/logsql/#min-stats) and [`max`](https://docs.victoriametrics.com/victorialogs/logsql/#max-stats) functions. Previously only numeric values could be passed to them.
* FEATURE: speed up [`sort ... limit N` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#sort-pipe) for typical cases.
* FEATURE: allow using more convenient syntax for [`range` filters](https://docs.victoriametrics.com/victorialogs/logsql/#range-filter) if upper or lower bound isn't needed. For example, it is possible to write `response_size:>=10KiB` instead of `response_size:range[10KiB, inf)`, or `temperature:<42` instead of `temperature:range(-inf, 42)`.
* FEATURE: add `/select/logsql/hits` HTTP endpoint for returning the number of matching logs per the given time bucket over the selected time range. See [these docs](https://docs.victoriametrics.com/victorialogs/querying/#querying-hits-stats) for details.
* FEATURE: add `/select/logsql/field_names` HTTP endpoint for returning [field](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model) names from results of the given query. See [these docs](https://docs.victoriametrics.com/victorialogs/querying/#querying-field-names) for details.
* FEATURE: add `/select/logsql/field_values` HTTP endpoint for returning unique values for the given [field](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model) obtained from results of the given query. See [these docs](https://docs.victoriametrics.com/victorialogs/querying/#querying-field-values) for details.
* BUGFIX: properly take into account `offset` at [`sort` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#sort-pipe) when it already has `limit`. For example, `_time:5m | sort by (foo) offset 20 limit 10`.

Released at 2024-03-01
Revert "removed unneeded ref shortcodes, updated VM changelog to use relative markdown links (#6691)" This reverts commit 2e9b1efeb9422c60a345c67ebbbcaa5f8d37469d. Reason for revert: relative links in docs are much harder to maintain in consistent state comparing to absolute links: - It is non-trivial to figure out the proper relative link path when creating and editing docs. - Relative links break after moving the doc files to another paths, and it is non-trivial to figure which links are broken after that. - The updated relative links do not work properly right now in the docs. For example, the https://docs.victoriametrics.com/victorialogs/quickstart.md#building-from-source-code link at https://docs.victoriametrics.com/victorialogs/changelog/ leads to 404 page. This is documented at https://docs.victoriametrics.com/#images-in-documentation .

* FEATURE: support the ability to limit the number of returned log entries from [HTTP querying API](https://docs.victoriametrics.com/victorialogs/querying/#http-api) by passing `limit` query arg. Previously all the matching log entries were returned until closing the response stream. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5674). Thanks to @dmitryk-dk for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5778).
app/vlselect: follow-up for 451d2abf50171dbdea844b40f14e0205a173d37a - Consistently return the first `limit` log entries if the total size of found log entries doesn't exceed 1Mb. See app/vlselect/logsql/sort_writer.go . Previously random log entries could be returned with each request. - Document the change at docs/VictoriaLogs/CHANGELOG.md - Document the `limit` query arg at docs/VictoriaLogs/querying/README.md - Make the change less intrusive.

2024-02-18 22:13:13 +01:00
* BUGFIX: properly determine when the assisted merge is needed. Previously the logs for determining whether the assisted merge is needed was broken. This could lead to too big number of parts under high data ingestion rate. Thanks to @lujiajing1126 for [the fix](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5447).

* BUGFIX: properly stop execution of aborted query when the query doesn't contain [`_stream` filter](https://docs.victoriametrics.com/victorialogs/logsql/#stream-filter). Previously such a query could continue consuming resources after being aborted by the client. Thanks to @z-anshun for [the fix](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5400).

2024-07-25 12:47:35 +02:00
* FEATURE: add `-elasticsearch.version` command-line flag, which can be used for specifying Elasticsearch version returned by VictoriaLogs to Filebeat at [elasticsearch bulk API](https://docs.victoriametrics.com/victorialogs/data-ingestion/#elasticsearch-bulk-api). This helps resolving [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4777).
* FEATURE: expose the following metrics at [/metrics](https://docs.victoriametrics.com/victorialogs/#monitoring) page:
* `vl_data_size_bytes{type="storage"}` - on-disk size for data excluding [log stream](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) indexes.
* `vl_data_size_bytes{type="indexdb"}` - on-disk size for [log stream](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) indexes.
app/vlinsert: add flag to limit amount of fields per line (#4976) Adding limit on ingestion allows to avoid issues like this one https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4762 Such issues are often caused by misconfigurtion on log persing/ingestion side and preventing such rows from being ingested allows to avoid performance implications created by storing such log rows.

2023-09-15 15:18:38 +02:00
* FEATURE: add `-insert.maxFieldsPerLine` command-line flag, which can be used for limiting the number of fields per line in logs sent to VictoriaLogs via ingestion protocols. This helps to avoid issues like [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4762).

* BUGFIX: add `/insert/loki/ready` endpoint, which is used by Promtail for healthchecks. This should remove `unsupported path requested: /insert/loki/ready` warning logs. See [this comment](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4762#issuecomment-1690966722).
lib/logstorage: follow-up for 94627113dbe0b7bed23a7dc4864fc2f2903a819c - Move uniqueFields from rows to blockStreamMerger struct. This allows localizing all the references to uniqueFields inside blockStreamMerger.mustWriteBlock(), which should improve readability and maintainability of the code. - Remove logging of the event when blocks cannot be merged because they contain more than maxColumnsPerBlock, since the provided logging didn't provide the solution for the issue with too many columns. I couldn't figure out the proper solution, which could be helpful for end user, so decided to remove the logging until we find the solution. This commit also contains the following additional changes: - It truncates field names longer than 128 chars during logs ingestion. This should prevent from ingesting bogus field names. This also should prevent from too big columnsHeader blocks, which could negatively affect search query performance, since columnsHeader is read on every scan of the corresponding data block. - It limits the maximum length of const column value to 256. Longer values are stored in an ordinary columns. This helps limiting the size of columnsHeader blocks and improving search query performance by avoiding reading too long const columns on every scan of the corresponding data block. - It deduplicates columns with identical names during data ingestion and background merging. Previously it was possible to pass columns with duplicate names to block.mustInitFromRows(), and they were stored as is in the block.

2024-07-25 12:47:35 +02:00
* FEATURE: support short form of `_time` filters over the last X minutes/hours/days/etc. For example, `_time:5m` is a short form for `_time:(now-5m, now]`, which matches logs with [timestamps](https://docs.victoriametrics.com/victorialogs/keyconcepts/#time-field) for the last 5 minutes. See [these docs](https://docs.victoriametrics.com/victorialogs/logsql/#time-filter) for details.
* FEATURE: add ability to specify offset for the selected time range. For example, `_time:5m offset 1h` is equivalent to `_time:(now-5m-1h, now-1h]`. See [these docs](https://docs.victoriametrics.com/victorialogs/logsql/#time-filter) for details.
* FEATURE: [LogsQL](https://docs.victoriametrics.com/victorialogs/logsql/): replace `exact_prefix("...")` with `exact("..."*)`. This makes it consistent with [i()](https://docs.victoriametrics.com/victorialogs/logsql/#case-insensitive-filter) filter, which can accept phrases and prefixes, e.g. `i("phrase")` and `i("phrase"*)`. See [these docs](https://docs.victoriametrics.com/victorialogs/logsql/#exact-prefix-filter).
