Bryce Lampe	74f8e12e87	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 02:22:37 +03:00
Aliaksandr Valialkin	30b8d91727	lib/promscrape/discoveryutils: always store just allocated string to sanitized label names cache ... This is a follow-up for c06e7a142c	2022-08-27 00:28:39 +03:00
Aliaksandr Valialkin	c06e7a142c	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 00:17:45 +03:00
Aliaksandr Valialkin	a2cd79576f	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 21:48:30 +03:00
Aliaksandr Valialkin	f49c9bb700	lib/promrelabel: optimize common regex mismatch cases for action: replace and action: labelmap	2022-08-26 15:45:31 +03:00
Aliaksandr Valialkin	4c6916f32a	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 15:23:45 +03:00
Aliaksandr Valialkin	7afe8450fc	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 14:53:06 +03:00
Aliaksandr Valialkin	0ad3bbadd3	lib/regexutil: add Simplify() function for simplifying the regular expression	2022-08-26 11:57:12 +03:00
Aliaksandr Valialkin	b373661988	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 23:23:55 +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	0d46e24af5	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 17:15:25 +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. This optimization should improve the speed for regexp series filters with explicit $ and ^ anchors. For example, `{label="^(foo|bar)$"}`	2022-08-24 17:12:52 +03:00
Aliaksandr Valialkin	796aa310c2	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 13:44:04 +03:00
Aliaksandr Valialkin	628e87e727	Merge branch 'public-single-node' into pmm-6401-read-prometheus-data-files	2022-08-22 00:40:04 +03:00
Aliaksandr Valialkin	1f89278d88	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 00:16:37 +03:00
Aliaksandr Valialkin	2c3a89339d	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 00:02:25 +03:00
Aliaksandr Valialkin	9f94c295ab	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 23:52:35 +03:00
Roman Khavronenko	d59d829cdb	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.

Aliaksandr Valialkin	7d26414b2e	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 13:19:33 +03:00
Aliaksandr Valialkin	bb68ab99fa	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	a0e7432e42	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.
