Aliaksandr Valialkin	6608705652	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 19:59:16 +03:00
Aliaksandr Valialkin	e3a91b186a	lib/protoparser/prometheus: optimize GetRowsDiff() function This should help https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1745 , since the provided profile shows that the majority of CPU and memory is spent in this function during `streamParse` when `-promscrape.noStaleMarkers` wasn't set.	2021-10-27 18:54:45 +03:00

Aliaksandr Valialkin	7fa15f7f86	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 16:44:44 +03:00
Aliaksandr Valialkin	6106d4069d	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 13:54:30 +03:00
Aliaksandr Valialkin	2876137c92	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 13:10:29 +03:00

Aliaksandr Valialkin	3408a05d12	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 13:20:40 +03:00

Aliaksandr Valialkin	06b0982d6b	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 13:18:23 +03:00
Aliaksandr Valialkin	32793adbd9	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 13:00:30 +03:00
Aliaksandr Valialkin	9866dd95c1	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 15:39:23 +03:00
Aliaksandr Valialkin	f6d33596ff	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 12:27:12 +03:00
Aliaksandr Valialkin	bbd34fa15e	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.

Aliaksandr Valialkin	d5622b32e2	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.

One minute is enough for caching the blocks needed for repeated queries (e.g. alerting rules, recording rules and dashboard refreshes).	2021-06-29 19:57:07 +03:00
Aliaksandr Valialkin	fc12484734	lib/mergeset: switch from sync.Pool to a channel for a pool for inmemoryBlock structs This should reduce memory usage for the pool on systems with big number of CPU cores. The sync.Pool maintains per-CPU pools, so the total number of objects in the pool is proportional to the number of available CPU cores. The channel limits the number of pooled objects by its own capacity. This means smaller number of pooled objects on average.	2021-06-29 19:56:59 +03:00

Aliaksandr Valialkin	aa9b56a046	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 13:52:08 +03:00
Aliaksandr Valialkin	84fb59b0ba	lib/storage: move deletedMetricIDs set from indexDB to Storage This makes consitent the list of deleted metricIDs when it is used from both the current indexDB and the previous indexDB (aka extDB). 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 15:04:30 +03:00

Aliaksandr Valialkin	c14dafce43	lib/promscrape: an attempt to reduce memory usage when vmagent scrapes targets with varying number of metrics Do not cache too big byte buffers and too big writeRequestCtx objects, since it is cheaper to re-create them instead of wasting RAM for their caching. This reverts `7f6f350ee1`	2021-03-15 11:45:39 +02:00
Aliaksandr Valialkin	7f6f350ee1	lib/promscrape: return back the logic for flushing big buffers to storage from the commit `3fd8653b40` This should reduce memory usage when vmagent scrapes targets with big number of metrics and `-promscrape.streamParse` isn't enabled	2021-03-14 22:26:00 +02:00

Aliaksandr Valialkin	e772d1c920	lib/promscrape/discovery/kubernetes: reduce load on Kubernetes API server by using watch bookmarks This allows continuing object watch from the last bookbark instead of reloading all the objects on watch errors or timeouts. See https://kubernetes.io/docs/reference/using-api/api-concepts/#watch-bookmarks	2021-03-10 15:06:35 +02:00
Aliaksandr Valialkin	bc5c4add89	lib/httpserver: export `vm_available_memory_bytes` and `vm_available_cpu_cores` metrics These metrics are useful for tracking the available memory and CPU cores for VictoriaMetrics apps.	2021-03-10 12:02:42 +02:00
Aliaksandr Valialkin	787242d7b0	lib/proxy: pass proxy hostname in `Host` header of the `CONNECT` request This should resolve the following issue when connecting to tls proxy: cannot validate certificate for ... because it doesn't contain any IP SANs	2021-03-09 20:39:40 +02:00
Aliaksandr Valialkin	36fd007247	lib/proxy: set missing ServerName in TLS config for `proxy_url`. While at it, allow setting Proxy-Authorization for `proxy_url` via `basic_auth` and `bearer_token` configs.	2021-03-09 18:58:18 +02:00

Aliaksandr Valialkin	3fd8653b40	lib/promscrape: apply `sample_limit` after metric relabeling is applied as Prometheus does See the description for `sample_limit` option from Prometheus docs: Per-scrape limit on number of scraped samples that will be accepted. If more than this number of samples are present after metric relabeling the entire scrape will be treated as failed. 0 means no limit. https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config	2021-03-09 15:47:18 +02:00

Aliaksandr Valialkin	ab4f090c63	lib/promscrape/discovery/kubernetes: reduce memory usage further when big number of scrape jobs are configured for the same `kubernetes_sd_config` role Serialize reloading per-role objects, so they don't occupy too much memory when objects for many scrape jobs are simultaneously refreshed. Do not reload per-role objects if they were already refreshed by concurrent goroutines. This should reduce load on Kubernetes API server when big number of scrape jobs are configured for the same Kubernetes role. This is a follow-up for `17b87725ed` Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113	2021-03-07 19:51:03 +02:00

Aliaksandr Valialkin	17b87725ed	lib/promscrape/discovery/kubernetes: reduce memory usage when Kubernetes service discovery is configured on a big number of scrape jobs Previously vmagent was creating a separate Kubernetes object cache per each scrape job. This could result in increased memory usage when monitoring a Kubernetes cluster with big number of objects (pods / nodes / services, etc.) as seen at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113 Now it uses a shared map of scrape objects across multiple scrape jobs.	2021-03-05 17:29:55 +02:00
