Roman Khavronenko	34fdc8881b	vmagent: add error log for skipped data block when rejected by receiv… (#1956) ... * vmagent: add error log for skipped data block when rejected by receiving side Previously, rejected data blocks were silently dropped - only metrics were update.

Aliaksandr Valialkin	b9363d9726	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.	2021-12-20 18:38:05 +02:00

Aliaksandr Valialkin	e1a715b0f5	lib/storage: convert alternate regexps into Graphite wildcards inside __graphite__ pseudo-label ...

Aliaksandr Valialkin	90c542af12	app: use relative paths instead of absolute paths for the supported http handlers on the main page ...

Aliaksandr Valialkin	7275ebf91a	app/vmstorage: export vm_cache_size_max_bytes metrics for determining capacity of various caches ... The vm_cache_size_max_bytes metric can be used for determining caches which reach their capacity via the following query: vm_cache_size_bytes / vm_cache_size_max_bytes > 0.9	2021-12-02 10:30:43 +02:00

Aliaksandr Valialkin	d0e7c0535e	lib/logger: show only explicitly set command-line flags in logs ... This reduces initial verbosity in logs	2021-10-28 11:00:52 +03:00
Aliaksandr Valialkin	74b8af9891	lib/promscrape: add collapse and expand buttons per each group of targets from the same scrape job	2021-10-27 20:03:24 +03:00
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	676ad70d9f	lib/envflag: use flag.Set for setting the flags from env vars ... This should make visible the set flags at flag.Visit(), which is used later for logging and exporting the `is_set` label for these flags at /metrics page	2021-10-20 00:41:08 +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	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. This is common case in Kubernetes monitoring.	2021-10-14 12:29:35 +03:00

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	8aa9bba9bd	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 16:28:41 +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

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 .
