Aliaksandr Valialkin	4dbf12254d	lib/promscrape: take into account the original job_name when creating an unique key per each scrape target ... This should handle the case when the original job_name has been changed in -promscrape.config , while the resulting job label remains the same because it is overriden via relabeling.	2021-12-21 16:42:42 +02:00

Aliaksandr Valialkin	b626d6d606	lib/promscrape: add collapse and expand buttons per each group of targets from the same scrape job	2021-10-27 20:04:03 +03:00
Aliaksandr Valialkin	2ebee4e741	app/{vmalert,vmagent}: improve the distribution of scrape offsets among targets / rules ... Previously only the lower part of 64-bit hash was used for calculating the offset. This may give uneven distribution in some cases. So let's use all the available 64 bits from the hash for calculating the offset.	2021-10-27 20:04:02 +03:00
Aliaksandr Valialkin	ad445a06cd	lib/promscrape: properly show proxy_url option value at /config page ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1755	2021-10-26 21:24:22 +03:00
Aliaksandr Valialkin	b08f51f5d3	lib/promscrape: do not populate response body to memory in stream parsing mode if -promscrape.noStaleMarkers is set ... The response body isn't used if -promscrape.noStaleMarkers is set after the commit 2876137c92 , so there is no sense in pupulating it in memory. This should reduce memory usage when scraping big responses. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1728#issuecomment-949630694	2021-10-22 16:49:21 +03:00
Aliaksandr Valialkin	6bc10f0623	lib/promscrape: do not sort original labels and do not intern label string for the original labels before the sharding code is executed ... This should reduce CPU and memory usage in shard mode when service discovery finds big number of scrape targets with many long labels. See https://docs.victoriametrics.com/vmagent.html#scraping-big-number-of-targets This is a follow-up after 9882cda8b9 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1728	2021-10-22 13:55:39 +03:00
Aliaksandr Valialkin	a8bcc3c276	lib/promscrape: reduce memory usage if -promscrape.noStaleMarkers command-line flag is passed ... Do not store in memory the response from the last scrape per each target if -promscrape.noStaleMarkers option is enabled. This should reduce memory usage when the scraped targets return large responses.	2021-10-22 13:22:08 +03:00
Aliaksandr Valialkin	ea69eef375	lib/promscrape/discovery/kubernetes: log a warning if role: endpoints discovers more than 1000 targets per a single endpoint ... In this case `role: endpointslice` must be used instead. See the following references: * https://kubernetes.io/docs/reference/labels-annotations-taints/#endpoints-kubernetes-io-over-capacity * https://github.com/kubernetes/kubernetes/pull/99975 * https://github.com/prometheus/prometheus/issues/7572#issuecomment-934779398	2021-10-19 13:22:28 +03:00
Nikolay	e84a063209	changes job source for /target api (#1723) ... use jobNameOriginal instead of relabeled as prometheus does https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1707	2021-10-19 09:00:05 +03:00
Aliaksandr Valialkin	fbcc8b5c7d	lib/promscrape: set honor_timestamps: true by default if this option isnt set explicitly in scrape configs ... This aligns the behavior to Prometheus - see https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config	2021-10-16 20:48:53 +03:00
Aliaksandr Valialkin	0a9be5ef9d	lib/promscrape: expose promscrape_series_limit_max_series and promscrape_series_limit_current_series metrics per each scrape target with the enabled unique series limiter	2021-10-16 19:14:13 +03:00
Aliaksandr Valialkin	99011c6b63	lib/promscrape: always initialize http client for stream parsing mode ... Stream parsing mode can be automatically enabled when scraping targets with big response bodies exceeding the -promscrape.minResponseSizeForStreamParse , so it must be always initialized.	2021-10-16 13:19:48 +03:00
Aliaksandr Valialkin	0f4fda1bda	lib/promscrape: store the last scraped response in compressed form if its size exceeds -promscrape.minResponseSizeForStreamParse ... This should reduce memory usage when scraping targets with big response bodies.	2021-10-16 13:00:11 +03:00
Aliaksandr Valialkin	0452a8d4e8	lib/promscrape: store the full response in stream parsing mode in scrapeWork.lastScrape byte slice ... This allows sending staleness marks and properly calculate scrape_series_added metric in stream parsing mode at the cost of the increased memory usage, since now the potentially big response is kept in the lastScrape byte slice per each scrapeWork. In practice the memory usage increase shouldn't be big, since the response size is usually much smaller than the parsed metrics from this response after the relabeling, which usually adds a big pile of target-specific labels per each metric.	2021-10-15 15:26:24 +03:00
Aliaksandr Valialkin	3e9beb0f8d	lib/promscrape/discovery/kubernetes: rename endpointslices.go -> endpointslice.go in order to be consistent with EndpointSlice struct name ... This is a follow-up for 31b42b30b6	2021-10-15 12:27:31 +03:00
Aliaksandr Valialkin	25421fa2ae	lib/promscrape: add -promscrape.minResponseSizeForStreamParse command-line option for automatic switching to stream parsing mode when scraping targets with big responses ... This should reduce memory usage when vmagent scrapes targets with non-uniform response sizes. This is common case in Kubernetes monitoring.	2021-10-14 12:30:55 +03:00
Aliaksandr Valialkin	bee130cc78	lib/promscrape: return error if sample_limit or series_limit options are set when stream parsing mode is enabled	2021-10-14 12:30:54 +03:00

Aliaksandr Valialkin	09670479cd	lib/promscrape: reduce CPU usage for common case when calculating scrape_series_added metric ... Also reduce CPU usage when applying `series_limit` to scrape targets with constant set of metrics. The main idea is to perform the calculations on scrape_series_added and series_limit only if the set of metrics exposed by the target has been changed. Scrape targets rarely change the set of exposed metrics, so this optimization should reduce CPU usage in general case.	2021-09-12 12:53:45 +03:00
Aliaksandr Valialkin	c339642858	lib/promscrape: add the actual job name to the labels of promscrape_series_limit_rows_dropped_total metric	2021-09-11 11:03:38 +03:00

Aliaksandr Valialkin	d613a018c8	lib/promscrape: add ability to set series_limit and stream_parse options via relabeling ... This allows managing these options on a per-target basis. Typical use case: to manage these options for pods via Kubernetes annotations.	2021-09-09 18:51:23 +03:00
Aliaksandr Valialkin	b64866e64c	lib/promscrape: add scrape_ prefix to job and target labels exported by promscrape_series_limit_rows_dropped_total metric ... This is needed in order to prevent from possible clash with the corresponding (job, target) labels for the job, which scrapes this metric.	2021-09-09 17:31:04 +03:00
Aliaksandr Valialkin	c4df601f43	lib/promscrape: add the ability to limit the number of unique series per each scrape target ... The number of series per target can be limited with the following options: * Global limit with `-promscrape.maxSeriesPerTarget` command-line option. * Per-target limit with `max_series: N` option in `scrape_config` section.

Aliaksandr Valialkin	67bc407747	lib/promscrape: reduce memory and CPU usage when Prometheus staleness tracking is enabled for metrics from deleted / disappeared scrape targets ... Store the scraped response body instead of storing the parsed and relabeld metrics. This should reduce memory usage, since the response body takes less memory than the parsed and relabeled metrics. This is especially true for Kubernetes service discovery, which adds many long labels for all the scraped metrics. This should also reduce CPU usage, since the marshaling of the parsed and relabeld metrics has been substituted by response body copying.

This option allows reducing CPU usage a bit when VictoriaMetrics is used for collecting and processing non-Prometheus data. For example, InfluxDB line protocol, Graphite, OpenTSDB, CSV, etc.	2021-08-18 13:58:06 +03:00
Aliaksandr Valialkin	f21fad53b4	lib/promscrape: add ability to disable sending Prometheus staleness markers with -promscrape.disableStaleMarkers command-line flag ...
