Roman Khavronenko	92212f04da	vmalert: avoid sending resolves for pending alerts (#498) ... Before the change we were sending notifications to notifier if following conditions are met: * alert is in Fire state * alert is in Inactive state We were sending Inactive notifications to resolve alert ASAP. Unfortunately, we were sending resolves for Pending alerts that become Inactive, which is wrong. In this change we delete alert from the active list if it was Pending and become Inactive. In this way we now have Inactive alerts only if they were in state Fire before. See test change for example.	2020-05-17 15:13:22 +01:00

Roman Khavronenko	8c8ff5d0cb	vmalert: cleanup and restructure of code to improve maintainability (#471) ... The change introduces new entity `manager` which replaces `watchdog`, decouples requestHandler and groups. Manager supposed to control life cycle of groups, rules and config reloads. Groups export an ID method which returns a hash from filename and group name. ID supposed to be unique identifier across all loaded groups. Some tests were added to improve coverage. Bug with wrong annotation value if $value is used in templates after metrics being restored fixed. Notifier interface was extended to accept context. New set of metrics was introduced for config reload.	2020-05-10 17:58:17 +01:00

Aliaksandr Valialkin	164278151f	app/vmselect/promql: add aggr_over_time(("aggr_func1", "aggr_func2", ...), m[d]) function ... This function can be used for simultaneous calculating of multiple `aggr_func*` functions that accept range vector. For example, `aggr_over_time(("min_over_time", "max_over_time"), m[d])` would calculate `min_over_time` and `max_over_time` for `m[d]`.	2020-01-10 21:18:06 +02:00
Aliaksandr Valialkin	c4632faa9d	app/vmselect/promql: add tmin_over_time(m[d]) and tmax_over_time(m[d]) functions ... These functions return timestamp in seconds for the minimum and maximum value for `m` over time range `d`	2020-01-10 19:39:28 +02:00
Aliaksandr Valialkin	f358fb72d1	app/{vmbackup,vmrestore}: add backup complete file to backup when it is complete and check for this file before restoring from backup ...

Aliaksandr Valialkin	3e09d38f29	app/vmselect/promql: fix results caching for multi-arg rollup functions such as quantile_over_time ... Previosly only a single arg was taken into account, so caching didn't work properly for multi-arg rollup funcs.	2020-01-03 20:49:08 +02:00
Aliaksandr Valialkin	a774120460	app/vmselect/promql: use scrapeInterval instead of window in denominator when calculating rate for the first point on the time series ... This should provide better estimation for `rate` in the beginning of time series.	2020-01-03 19:01:50 +02:00
Aliaksandr Valialkin	b5645ccbdf	app/vmselect/promql: increase the estimated number of time series returned by aggr() by (something) from 100 to 1K, since 100 may result in OOM for high number of time series	2020-01-03 01:02:21 +02:00

Aliaksandr Valialkin	9e19949c6b	app/vmselect/promql: adjust calculations for rate and increase for the first value ... These calculations should trigger alerts on `/api/v1/query` for counters starting from values greater than 0.	2019-12-24 19:39:25 +02:00
Aliaksandr Valialkin	0455c03cb9	app/vmselect/promql: properly calculate rate on the first data point ... It is calculated as `value / scrape_interval`, since the value was missing on the previous scrape, i.e. we can assume its value was 0 at this time.	2019-12-24 15:55:52 +02:00

The metricID->metricName entry can be missing in the indexdb after unclean shutdown when only a part of entries for new time series is written into indexdb. Recover from such a situation by removing the broken metricID.

Aliaksandr Valialkin	1f3fd2c910	app/vmselect: adjust end arg instead of adjusting start arg if start > end ... `start` arg has higher chances to be set properly comparing to `end` arg, so it is expected that the `end` arg could be adjusted if it was set incorrectly.	2019-11-22 16:12:19 +02:00

Aliaksandr Valialkin	86a1cd700b	lib/storage: remove inmemory index for recent hour, since it uses too much memory ... Production workload shows that the index requires ~4Kb of RAM per active time series. This is too much for high number of active time series, so let's delete this index. Now the queries should fall back to the index for the current day instead of the index for the recent hour. The query performance for the current day index should be good enough given the 100M rows/sec scan speed per CPU core.	2019-11-13 17:58:07 +02:00

Aliaksandr Valialkin	ca259864e2	lib/storage: return back inmemory inverted index for recent hour ... Issues fixed: - Slow startup times. Now the index is loaded from cache during start. - High memory usage related to superflouos index copies every 10 seconds.	2019-11-13 13:11:04 +02:00
Aliaksandr Valialkin	01bb3c06c7	lib/storage: remove inmemory inverted index for recent hours ... Production load with >10M active time series showed it could slow down VictoriaMetrics startup times and could eat all the memory leading to OOM. Remove inmemory inverted index for recent hours until thorough testing on production data shows it works OK.	2019-11-13 10:45:53 +02:00
Aliaksandr Valialkin	6c2303764e	Revert "lib/fs: do not postpone directory removal on NFS error" ... This reverts commit 4c02e496f7. Reason for revert: the commit breaks on NFS - see https://github.com/VictoriaMetrics/VictoriaMetrics/issues/234	2019-11-12 16:18:09 +02:00

Aliaksandr Valialkin	4c02e496f7	lib/fs: do not postpone directory removal on NFS error ... Continue trying to remove NFS directory on temporary errors for up to a minute. The previous async removal process breaks in the following case during VictoriaMetrics start - VictoriaMetrics opens index, finds incomplete merge transactions and starts replaying them. - The transaction instructs removing old directories for parts, which were already merged into bigger part. - VictoriaMetrics removes these directories, but their removal is delayed due to NFS errors. - VictoriaMetrics scans partition directory after all the incomplete merge transactions are finished and finds directories, which should be removed, but weren't still removed due to NFS errors. - VictoriaMetrics panics when it finds unexpected empty directory.

Aliaksandr Valialkin	63b05c0b9f	app/vmselect/promql: adjust memory limits calculations for incremental aggregate functions ... Incremental aggregate functions don't keep all the selected time series in memory - they keep only up to GOMAXPROCS time series for incremental aggregations. Take into account that the number of time series in RAM can be higher if they are split into many groups with `by (...)` or `without (...)` modifiers. This should reduce the number of `not enough memory for processing ... data points` false positive errors.	2019-11-08 21:21:07 +02:00
Aliaksandr Valialkin	d888b21657	lib/storage: add inmemory inverted index for the last hour ... It should improve performance for `last N hours` dashboards with update intervals smaller than 1 hour.	2019-11-08 21:21:07 +02:00

The origin of the error has been detected and documented in the code, so it is enough to export a counter for such errors at `vm_index_blocks_with_metric_ids_incorrect_order_total`, so it could be monitored and alerted on high error rates. Export also the counter for processed index blocks with metricIDs - `vm_index_blocks_with_metric_ids_processed_total`, so its' rate could be compared to `rate(vm_index_blocks_with_metric_ids_incorrect_order_total)`.	2019-11-06 14:28:11 +02:00

Aliaksandr Valialkin	c66a691593	app/vmselect/prometheus: add -search.maxLookback command-line flag for overriding dynamic calculations for max lookback interval ... This flag is similar to `-search.lookback-delta` if set. The max lookback interval is determined dynamically from interval between datapoints for each input time series if the flag isn't set. The interval can be overriden on per-query basis by passing `max_lookback=<duration>` query arg to `/api/v1/query` and `/api/v1/query_range`.
