Aliaksandr Valialkin	e86b7cc9a5	lib/workingsetcache: use the original cache size limits when rotating caches ... Previously limits for new caches were taken from cache stats. These limits could mismatch the original limits. This could result in failed cache load if the stored cache has been created with the limits obtained from cache stats.	2022-02-08 00:10:14 +02:00
Aliaksandr Valialkin	cde4664f0d	lib/blockcache: return proper number of entries from the cache ... This has been broken in 0d7374ad2f	2022-02-07 19:28:42 +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

匠心零度	1999bbfe82	optimized code (#2103) ... * optimized code ,because only the first error,so no need var errors []error * optimized code ,because only the first error,so no need var errors []error Co-authored-by: lirenzuo <lirenzuo@shein.com>	2022-01-28 14:15:41 +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	91f2af2d7a	lib/mergeset: allocate the needed amounts of memory when unmarshaling inmemoryBlock ... This should reduce the memory required for indexdb/dataBlocks cache. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2007	2022-01-24 18:50:40 +02:00

Aliaksandr Valialkin	746ee191e8	lib/logger/throttler.go: show the original location of the error and warning message ... Previously the location inside LogThrottler implementation was shown. This could complicate debugging.	2022-01-23 13:55:00 +02:00
Aliaksandr Valialkin	0d7374ad2f	lib/blockcache: optimize blockcache a bit ... - Optimize Cache.RemoveBlocksFromPart(), so it doesn't need to iterate over all the cached blocks. - Cache blocks if there were no cache misses during the last 2 minutes. This may be the case when new blocks are added simultaneously to the storage and to the cache. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2007	2022-01-23 13:13:45 +02:00
Aliaksandr Valialkin	ede93469ea	lib/mergeset: tune caches size limits for indexdb/dataBlocks and indexdb/indexBlocks ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2007	2022-01-21 12:45:43 +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.

Aliaksandr Valialkin	1d20a19c7d	lib/storage: explicitly pass dedupInterval to DeduplicateSamples() and deduplicateSamplesDuringMerge() ... This improves the code readability and debuggability, since the output of these functions stops depending on global state.	2021-12-14 20:49:12 +02:00
Aliaksandr Valialkin	e1a715b0f5	lib/storage: convert alternate regexps into Graphite wildcards inside __graphite__ pseudo-label ...

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	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. Scrape targets rarely change the set of exposed metrics, so this optimization should reduce CPU usage in general case.	2021-09-12 12:53:14 +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.
