Aliaksandr Valialkin	f50cf60534	lib/cgroup: fall back to runtime.NumCPU() when determining process_cpu_cores_available metric if it is impossible to determine cpu quota via cgroups ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2107	2022-01-31 20:30:14 +02:00
Aliaksandr Valialkin	ead66155ef	lib/cgroup: expose process_cpu_cores_available metric ... This metric shows the number of CPU cores available to the process. This allows creating alerting rules on CPU saturation with the following query: rate(process_cpu_seconds_total[5m]) / process_cpu_cores_available > 0.9 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2107	2022-01-31 20:24:41 +02:00

Aliaksandr Valialkin	f4989edd96	lib/bytesutil: split Resize() into ResizeNoCopy() and ResizeWithCopy() functions ... Previously bytesutil.Resize() was copying the original byte slice contents to a newly allocated slice. This wasted CPU cycles and memory bandwidth in some places, where the original slice contents wasn't needed after slize resizing. Switch such places to bytesutil.ResizeNoCopy(). Rename the original bytesutil.Resize() function to bytesutil.ResizeWithCopy() for the sake of improved readability. Additionally, allocate new slice with `make()` instead of `append()`. This guarantees that the capacity of the allocated slice exactly matches the requested size. The `append()` could return a slice with bigger capacity as an optimization for further `append()` calls. This could result in excess memory usage when the returned byte slice was cached (for instance, in lib/blockcache). Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2007	2022-01-25 15:24:44 +02:00

Aliaksandr Valialkin	145337792d	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.

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

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.

This is especially true for Kubernetes service discovery, which adds many long labels for all the scraped metrics.

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	7c6d3981bf	lib/uint64set: allow reusing bucket16 structs inside uint64set.Set via uint64set.Release method ... This reduces the load on memory allocator in Go runtime in production workload.	2021-07-06 15:35:03 +03:00
Aliaksandr Valialkin	78c9174682	lib/mergeset: increase pool capacity for inmemoryBlock according to collected profiles from production workload ... CPU and memory profiles show that the pool capacity for inmemoryBlock objects is too small. This results in the increased load on memory allocation code in Go runtime. Increase the pool capacity in order to reduce the load on Go runtime.	2021-07-06 13:41:34 +03:00
Aliaksandr Valialkin	f71e4d1853	lib/mergeset: limit the frequency for flushCallback calls to once per 10 seconds ... This should improve hit ratio for tagFiltersCache when big number of new time series are constantly registered (aka high churn rate). This, in turn, should reduce CPU usage for queries over such time series.	2021-07-06 12:17:17 +03:00

Aliaksandr Valialkin	0020b9f904	lib/workingsetcache: properly update stats for requests and cache misses ... Previously the stats for cache misses could be improperly counted, because it had inflated cache misses if the entry was missing in the curr cache, but was existing in the prev cache. The same applies to cache requests - they were inflated if the entry was missing in the curr cache.	2021-07-06 10:53:32 +03:00

Aliaksandr Valialkin	8f973e34fb	lib/workingsetcache: properly switch to whole mode ... 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. This change can reduce memory usage for data ingestion path when big number of active time series are ingested.	2021-07-05 15:16:11 +03:00
Aliaksandr Valialkin	43103be011	lib/{storage,mergeset}: increase cache timeout for data and index blocks from a minute to two minutes ...

Aliaksandr Valialkin	c93cee8de8	lib/{mergeset,storage}: reduce the maximum lifetime for cached indexdb and data blocks from 2 minutes to a minute ... This should reduce memory usage on a system with high number of active time series and a high churn rate. 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

Tune the logic according to the logs provided at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338#issuecomment-864293624 The previous logic had a race when multiple concurrent queries execute the same tag filter without prior stats.
