Aliaksandr Valialkin	5159a9451f	lib/blockcache: add missing dependency after 145337792d ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2007	2022-01-20 18:51:03 +02:00
Aliaksandr Valialkin	6ae584b9b3	lib/{mergeset,storage}: properly limit cache sizes for indexdb ... Previously these caches could exceed limits set via `-memory.allowedPercent` and/or `-memory.allowedBytes`, since limits were set independently per each data part. If the number of data parts was big, then limits could be exceeded, which could result to out of memory errors.

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	92d01db85a	lib/protoparser/prometheus: optimize GetRowsDiff() function ...

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 ...

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

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 ...

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 ...

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	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.

Aliaksandr Valialkin	b805a675f3	lib/{mergeset,storage}: switch from sync.Pool to chan-based pool for inmemoryPart objects ... This should reduce memory usage on systems with big number of CPU cores, since every inmemoryPart object occupies at least 64KB of memory and sync.Pool maintains a separate pool inmemoryPart objects per each CPU core. Though the new scheme for the pool worsens per-cpu cache locality, this should be amortized by big sizes of inmemoryPart objects.	2021-07-06 16:33:25 +03:00

Previously the switch from `split` to `whole` mode had been performed too early, e.g. when the current cache size became bigger than 1/4 of the allowed cache size. Now it is performed when the current cache size becomes bigger than 1/2 of the allowed cache size.

Aliaksandr Valialkin	0efd37cec1	lib/{mergeset,storage}: reduce the number of fsync calls on data ingestion path on systems with many cpu cores ... VictoriaMetrics maintains a buffer per CPU core for the ingested data. These buffers are flushed to disk every second. These buffers are flushed to disk in parallel starting from the commit 56b6b893ce . This resulted in increased write disk IO usage on systems with many cpu cores as described at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338#issuecomment-863046999 . This commit merges the per-CPU buffers into bigger in-memory buffers before flushing them to disk. This should reduce the rate of fsync syscalls and, consequently, the write disk IO on systems with many CPU cores. This should help https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338 See also https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1244	2021-06-17 13:51:42 +03:00

This should fix the issue, which could lead to storing new samples under deleted metricIDs after indexDB rotation. See more details at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1347#issuecomment-861232136 . Thanks to @tangqipengleoo for the initial analysis and the pull request - https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 . This commit resolves the issue in more generic way compared to https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 . The downside of the commit is the deletedMetricIDs set isn't cleaned from the metricIDs outside the retention. It needs app restart. This should be OK in most cases.	2021-06-15 15:07:54 +03:00
