Aliaksandr Valialkin	d0a9ca1bc2	lib/storage: properly pass uint64 constant to fmt.Errorf on 32-bit platforms	2022-10-23 12:48:00 +03:00
Aliaksandr Valialkin	5e4dfe50c6	lib/storage: subsitute searchTSIDs functions with more lightweight searchMetricIDs function ... The searchTSIDs function was searching for metricIDs matching the the given tag filters and then was locating the corresponding TSID entries for the found metricIDs. The TSID entries aren't needed when searching for time series names (aka MetricName), so this commit removes the uneeded TSID search from the implementation of /api/v1/series API. This improves perfromance of /api/v1/series calls. This commit also improves performance a bit for /api/v1/query and /api/v1/query_range calls, since now these calls cache small metricIDs instead of big TSID entries in the indexdb/tagFilters cache (now this cache is named indexdb/tagFiltersToMetricIDs) without the need to compress the saved entries in order to save cache space. This commit also removes concurrency limiter during searching for matching time series, which was introduced in 8f16388428, since the concurrency for all the read queries is already limited with -search.maxConcurrentRequests command-line flag.

Aliaksandr Valialkin	99d67ac8ad	lib/storage: validate timestamps in the block only if they use encoding, which needs validation ... This reduces CPU usage when there is no sense in validating timestamps. This is a follow-up for 5fa9525498 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2998 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3011	2022-10-21 00:52:32 +03:00
Aliaksandr Valialkin	3f5959c053	lib/storage: try generating initial parts from inmemory rows with identical sizes under high ingestion rate ... This should improve background merge rate under high load a bit	2022-10-20 23:28:24 +03:00
Aliaksandr Valialkin	891ff6af2a	lib/workingsetcache: increase default cache expiration from 10 minutes to 20 minutes ... This increases the maximum time for cache population with new entries from 20 minutes to 40 minutes. This This change shouldn't increase memory usage for caches, since the prev cache cleaner should free up memory by deleting unused prev cache as soon as possible. See 08ca45d238 for details on prev cache cleaner.	2022-10-20 21:48:25 +03:00

Aliaksandr Valialkin	d906d8573e	lib/workingsetcache: drop the previous cache whenever it recieves less than 5% of requests comparing to the current cache ... This means that the majority of requests are successfully served from the current cache, so the previous cache can be reset in order to free up memory.	2022-10-20 10:47:58 +03:00
Aliaksandr Valialkin	817aeafd69	lib/workingsetcache: use per-bucket stats counters instead of global stats counters for cache hits/misses ... This should improve cache scalability on systems with many CPU cores.	2022-10-20 09:12:17 +03:00

Aliaksandr Valialkin	f9df0cae16	lib/promscrape: allow specifying full target url in __address__ label ... Previously the `__address__` label could contain only `host:port` part of the target url, while the scheme and metrics path were obtained from `__scheme__` and `__metrics_path__` labels. Now it is possible to set the full url in `__address__` label. This makes valid the following scrape config, which is frequently used by novice users: scrape_configs: - job_name: foo static_configs: - targets: - http://host1/metrics1 - https://host2/metrics2	2022-10-07 22:43:04 +03:00

Aliaksandr Valialkin	0d4ea03a73	lib/promrelabel: optimize action: {labeldrop,labelkeep,keep,drop} with regex containing alternate values ... For example, the following relabeling rule must work much faster now: - action: labeldrop regex: "foo|bar|baz"	2022-08-24 17:54:29 +03:00

Aliaksandr Valialkin	fdbf5b5795	lib/storage: ignore start text and end text anchors in getOrValues(regexp) function ... This is OK, since the anchors are implicitly applied to the whole regexp.

Aliaksandr Valialkin	b958fc7846	lib/storage: properly take into account already registered series when -storage.maxHourlySeries or -storage.maxDailySeries limits are enabled ... The commit 5fb45173ae takes into account only newly registered series when applying cardinality limits. This means that the cardinality limit could be exceeded with already registered series.

Roman Khavronenko	1ee1e986da	lib/storage: limit max mergeConcurrency value for systems with high number of CPUs (#2673) ... Workers count for merges affects the max part size during merges. Such behaviour protects storage from running out of disk space for scenario when all workers are merging parts with the max size. This works very well for most cases. But for systems where high number of CPUs is allocated for vmstorage components this could significantly impact the max part size and result in more unmerged parts than expected. While checking multiple production highly loaded setups it was discovered that `max_over_time(vm_active_merges{type="storage/big}[1h]}"` rarely exceeds 2, and `max_over_time(vm_active_merges{type="storage/small}[1h]}"` rarely exceeds 4. The change in this commit limits the max value for concurrency accordingly. Signed-off-by: hagen1778 <roman@victoriametrics.com>	2022-06-07 14:55:09 +03:00

This allows properly updating scrape targets after these values are updated in configs. - Do not re-generate certificate from `key` and `cert` values per each call to getTLSCert, because these values are immutable. - Do not set `ca` value from `ca_file` value, so it isn't exposed at `/config` page. - Generate proper error messages on incorrect `key`, `cert` or `ca` values.	2022-06-04 01:01:16 +03:00
