Aliaksandr Valialkin	087393bcef	lib/promrelabel: remove unconditional sorting of the labels in ParsedConfigs.Apply(), since the sorting isnt needed in many places ... Sort labels explicitly after calling the ParsedConfigs.Apply() when needed. This reduces CPU usage when performing metric-level relabeling, where labels' sorting isn't needed.	2022-10-09 14:53:35 +03:00
Aliaksandr Valialkin	3b828535f0	lib/promscrape: allow controlling staleness tracking on a per-scrape_config basis ... Add support for no_stale_markers option at scrape_config section. See https://docs.victoriametrics.com/sd_configs.html#scrape_configs and https://docs.victoriametrics.com/vmagent.html#prometheus-staleness-markers	2022-10-07 23:37:31 +03:00
Aliaksandr Valialkin	3987b0abd1	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 22:46:29 +03:00
Aliaksandr Valialkin	f0a748a3aa	lib/promscrape/discovery/azure: remove unneeded conversion to string	2022-10-01 16:15:00 +03:00
Aliaksandr Valialkin	735de9ee54	lib/promscrape: add external_labels from global section of -promscrape.config after the relabeling is applied to the scraped metrics ... This aligns with Prometheus behaviour. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3137	2022-10-01 16:15:00 +03:00
Aliaksandr Valialkin	c628f5b6eb	lib/promscrape/discovery/ec2: expose __meta_ec2_region label in the same way as Prometheus 2.39 does ... See https://github.com/prometheus/prometheus/pull/11326	2022-09-30 20:49:08 +03:00
Aliaksandr Valialkin	b4bb1477fe	lib/regexutil: cache MatchString results for unoptimized regexps ... This increases relabeling performance by 3x for unoptimized regexs	2022-09-30 12:28:25 +03:00
Aliaksandr Valialkin	c0aa10bd73	lib/bytesutil: move InternString() from lib/promscrape/discoverytutils to lib/bytesutil ... lib/bytesutil is more appropriate place for InternString() function	2022-09-30 07:34:59 +03:00

Aliaksandr Valialkin	2351468bc4	lib/promscrape: read response body into memory in stream parsing mode before parsing it ... This reduces scrape duration for targets returning big responses. The response body was already read into memory in stream parsing mode before this change, so this commit shouldn't increase memory usage.	2022-09-14 13:29:39 +03:00
Aliaksandr Valialkin	592612b63f	lib/promscrape/discovery/kubernetes: add more context on WatchEvent parse error ... This should improve debugging issues with Kubernetes API server	2022-09-13 19:37:40 +03:00

Aliaksandr Valialkin	86394b4179	lib/promscrape: optimize discoveryutils.SanitizeLabelName() ... Cache sanitized label names and return them next time.

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.

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
Aliaksandr Valialkin	1812d33a2d	lib/promscrape: automatically generate additional per-target labels for targets with non-zero series limit ...
