Aliaksandr Valialkin	051e722112	lib/storage: verify that timestamps in block are in the range specified by blockHeader.{Min,Max}Timestamp when upacking the block ... This should reduce chances of unnoticed on-disk data corruption. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2998 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3011 This change modifies the format for data exported via /api/v1/export/native - now this data contains MaxTimestamp and PrecisionBits fields from blockHeader. This is OK, since the native export format is undocumented.	2022-09-06 13:07:49 +03:00
Bryce Lampe	5f7f1d5aea	Support "HTTP" and "HTTPS" schemes (#3019) ... * Support "HTTP" and "HTTPS" schemes * Update lib/promscrape/config.go Co-authored-by: Aliaksandr Valialkin <valyala@gmail.com>	2022-08-27 02:23:52 +03:00
Aliaksandr Valialkin	04761419ba	lib/promscrape/discoveryutils: always store just allocated string to sanitized label names cache ... This is a follow-up for c06e7a142c	2022-08-27 00:29:59 +03:00
Aliaksandr Valialkin	86394b4179	lib/promscrape: optimize discoveryutils.SanitizeLabelName() ... Cache sanitized label names and return them next time. This reduces the number of allocations and speeds up the SanitizeLabelName() function for common case when the number of unique label names is smaller than 100k	2022-08-27 00:18:19 +03:00
Aliaksandr Valialkin	cead9c1e67	lib/promrelabel: call PromRegex.MatchString() on a slow path only if it contains non-empty literal prefix ... This should improve slow path speed for regexps without literal prefixes	2022-08-26 21:48:09 +03:00
Aliaksandr Valialkin	427d69e775	lib/promrelabel: optimize common regex mismatch cases for action: replace and action: labelmap	2022-08-26 15:48:11 +03:00
Aliaksandr Valialkin	da7697fda4	lib/promrelabel: use regexutil.PromRegex for regex matching in actions labeldrop,labelkeep,drop and keep ... This makes possible optimizing additional cases inside regexutil.PromRegex	2022-08-26 15:48:11 +03:00
Aliaksandr Valialkin	e1bd38fa97	lib/promrelabel: optimize matching for commonly used regex patterns in if option ... The following regex patterns are optimized: - literal string match, e.g. "foo" - prefix match, e.g. "foo.*" and "foo.+" - substring match, e.g. ".*foo.*" and ".+foo.+" - alternate values match, e.g. "foo|bar|baz"	2022-08-26 14:55:13 +03:00
Aliaksandr Valialkin	c49751adf8	lib/regexutil: add Simplify() function for simplifying the regular expression	2022-08-26 11:57:43 +03:00
Aliaksandr Valialkin	909e681024	lib/promrelabel: optimize action: {drop,keep,labeldrop,labelkeep} with anchored regex prefix ... The following commonly used relabeling rules must work faster now: - action: labeldrop regex: "^foo.+$" - action: labeldrop regex: "^bar.*"	2022-08-25 23:24:38 +03:00
Aliaksandr Valialkin	d60654eb0a	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 17:55:54 +03:00
Aliaksandr Valialkin	891eb608df	lib/storage: increase the maximum possible or values extracted from regexp from 20 to 100 ... This should improve time series search speed for regexp filters with big number of `or` values.	2022-08-24 17:16:29 +03:00
Aliaksandr Valialkin	1b14cf18b6	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. This optimization should improve the speed for regexp series filters with explicit $ and ^ anchors. For example, `{label="^(foo|bar)$"}`	2022-08-24 17:16:28 +03:00
Aliaksandr Valialkin	7b9ba456ff	app/vmstorage: expose vm_{hourly,daily}_series_limit_{max,current}_series metrics if -storage.max{Hourly,Daily}Series limits are set ... These metrics allow alerting when the number of unique series approach the limit. For example, the following query alerts when the number of series reaches 90% of the configured limit: vm_hourly_series_limit_current_series / vm_hourly_series_limit_max_series > 0.9	2022-08-24 13:41:57 +03:00
Aliaksandr Valialkin	1905618d10	all: subsitute ioutil.ReadAll with io.ReadAll ... ioutil.ReadAll is deprecated since Go1.16 - see https://tip.golang.org/doc/go1.16#ioutil VictoriaMetrics requires at least Go1.18, so it is OK to switch from ioutil.ReadAll to io.ReadAll. This is a follow-up for 02ca2342ab	2022-08-22 00:16:04 +03:00
Aliaksandr Valialkin	88e0fe9469	all: use os.ReadDir instead of ioutil.ReadDir ... The ioutil.ReadDir is deprecated since Go1.16 - see https://tip.golang.org/doc/go1.16#ioutil VictoriaMetrics requires at least Go1.18, so it is time to switch from io.ReadDir to os.ReadDir This is a follow-up for 02ca2342ab	2022-08-22 00:04:09 +03:00
Aliaksandr Valialkin	06f6de6d47	all: use os.{Read|Write}File instead of ioutil.{Read|Write}File ... The ioutil.{Read|Write}File is deprecated since Go1.16 - see https://tip.golang.org/doc/go1.16#ioutil VictoriaMetrics needs at least Go1.18, so it is safe to remove ioutil usage from source code. This is a follow-up for 02ca2342ab	2022-08-21 23:55:20 +03:00
Roman Khavronenko	fc2b8b4efd	lib/storage: bump max merge concurrency for small parts to 15 (#2997) ... * lib/storage: bump max merge concurrency for small parts to 15 The change is based on the feedback from users on github. Thier examples show, that limit of 8 sometimes become a bottleneck. Users report that without limit concurrency can climb up to 15-20 merges at once.

Aliaksandr Valialkin	1812d33a2d	lib/promscrape: automatically generate additional per-target labels for targets with non-zero series limit ... The following metrics are generated: - scrape_series_limit - scrape_series_current - scrape_series_limit_samples_dropped These metrics simplify alerting on targets, which expose too many time series See https://docs.victoriametrics.com/vmagent.html#automatically-generated-metrics and https://docs.victoriametrics.com/vmagent.html#cardinality-limiter for more details	2022-08-17 13:22:02 +03:00
Aliaksandr Valialkin	aa37e6b438	lib/promscrape: retry http requests if the server returns 429 status code ... The 429 status code means that the server is overwhelmed with requests.

Roman Khavronenko	f42853275f	lib/storage: prevent excessive loops when storage is in RO (#2962) ... * lib/storage: prevent excessive loops when storage is in RO Returning nil error when storage is in RO mode results into excessive loops and function calls which could result into CPU exhaustion.
