Nikolay	0e09fdb8b0	makes filters optional for ec2 api requests (#1627) ... filters can be applied only for DescribeInstances requests, like prometheus does. related issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1626	2021-09-17 18:00:37 +03:00
Aliaksandr Valialkin	fb6ed0ce19	lib/promscrape/discovery/docker: support host networking mode ... See https://github.com/prometheus/prometheus/issues/9116	2021-09-13 13:30:16 +03:00
Aliaksandr Valialkin	6295861acd	lib/promscrape/discovery/kubernetes: properly use https scheme for wildcard TLS certificates in ingress target discovery	2021-09-13 13:03:42 +03:00
Aliaksandr Valialkin	728c4c3841	lib/promscrape: generate scrape_timeout_seconds metric per each scrape target in the same way as Prometheus 2.30 does ... See https://github.com/prometheus/prometheus/pull/9247	2021-09-12 15:20:44 +03:00
Aliaksandr Valialkin	0b4eb0fa7d	lib/promscrape: make fmt	2021-09-12 13:34:15 +03:00
Aliaksandr Valialkin	48e3e6c8df	lib/promscrape: add ability to configure scrape_timeout and scrape_interval via relabeling ... See https://github.com/prometheus/prometheus/pull/8911	2021-09-12 13:33:41 +03:00
Aliaksandr Valialkin	f3e89754a9	lib/promscrape: reduce CPU usage for common case when calculating scrape_series_added metric ... 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
Aliaksandr Valialkin	9286107e82	lib/promscrape: send stale markers for disappeared metrics like Prometheus does	2021-09-11 10:51:04 +03:00
Aliaksandr Valialkin	4aeb8db83f	lib/promscrape: add ability to set series_limit and stream_parse options via relabeling ... This allows managing these options on a per-target basis. Typical use case: to manage these options for pods via Kubernetes annotations.	2021-09-09 18:49:39 +03:00
Aliaksandr Valialkin	468f941f7e	lib/promscrape: add the actual job name to the labels of promscrape_series_limit_rows_dropped_total metric	2021-09-09 17:37:37 +03:00
Aliaksandr Valialkin	086b5d0cf1	lib/promscrape: add scrape_ prefix to job and target labels exported by promscrape_series_limit_rows_dropped_total metric ... This is needed in order to prevent from possible clash with the corresponding (job, target) labels for the job, which scrapes this metric.	2021-09-09 17:29:21 +03:00
Aliaksandr Valialkin	f77dde837a	lib/promscrape: add the ability to limit the number of unique series per each scrape target ... The number of series per target can be limited with the following options: * Global limit with `-promscrape.maxSeriesPerTarget` command-line option. * Per-target limit with `max_series: N` option in `scrape_config` section. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1561	2021-09-01 16:03:59 +03:00
Aliaksandr Valialkin	5c63d69454	lib/promscrape/discovery/kubernetes: return back support role: endpointslices, since it is used by VictoriaMetrics operator ... This is a follow up commit after 31b42b30b6	2021-08-29 12:37:03 +03:00
Aliaksandr Valialkin	31b42b30b6	lib/promscrape/discovery/kubernetes: rename role: endpointslices to role: endpointslice to be consistent with Prometheus ... See 2ec6c7dbb8/discovery/kubernetes/kubernetes.go (L99)	2021-08-29 11:23:08 +03:00
Aliaksandr Valialkin	2e001db4de	lib/promscrape/discovery/kubernetes: use v1 API instead of v1beta1 API for role: ingress and role: endpointslices ... This should fix service discovery for these roles in Kubernetes v1.22 and newer versions. See https://kubernetes.io/docs/reference/using-api/deprecation-guide/#ingress-v122 The corresponding change in Prometheus - https://github.com/prometheus/prometheus/pull/9205	2021-08-29 11:16:59 +03:00
Aliaksandr Valialkin	10f960fa0c	lib/promscrape: add ability to load scrape configs from multiple files ... See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1559	2021-08-26 08:51:16 +03:00
Aliaksandr Valialkin	c27ee35c5c	lib/promscrape: expose promscrape_discovery_http_errors_total metric for tracking errors per each http_sd config	2021-08-25 13:05:49 +03:00
Aliaksandr Valialkin	d5622b32e2	lib/promscrape: reduce memory and CPU usage when Prometheus staleness tracking is enabled for metrics from deleted / disappeared scrape targets ... 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. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1526	2021-08-21 21:17:26 +03:00
Aliaksandr Valialkin	f46a73dcdd	lib/promscrape: use scrapeTimestamp when storing stale markers for failed scrape ... This will make timestamps for stale markers more consistent for timestamps for other samples	2021-08-19 14:18:05 +03:00
Aliaksandr Valialkin	c09446a9aa	lib/promscrape: send stale markers for the previously scraped metrics on failed scrapes like Prometheus does	2021-08-18 21:59:03 +03:00
Aliaksandr Valialkin	cdc372bb98	app/vmselect: add -search.noStaleMarkers command-line flag for disabling stale markers handling in queries ... This option allows reducing CPU usage a bit when VictoriaMetrics is used for collecting and processing non-Prometheus data. For example, InfluxDB line protocol, Graphite, OpenTSDB, CSV, etc.	2021-08-18 13:59:02 +03:00
Aliaksandr Valialkin	226143f31b	lib/promscrape: add ability to disable sending Prometheus staleness markers with -promscrape.disableStaleMarkers command-line flag ... This option can be useful when vmagent consumes too much additional memory for staleness markers functionality and when staleness markers aren't needed.	2021-08-18 13:43:21 +03:00
Aliaksandr Valialkin	03c959f1df	lib/promscrape: stop scrapers for the removed targets before starting scrapers for the added targets ...

Aliaksandr Valialkin	f010d773d6	lib/promscrape/discovery/kubernetes: synchronously load Kubernetes objects on first access ... Remove async registration of apiWatchers, since it breaks discovering `role: endpoints` and `role: endpointslices` targets, which depend on pod and service objects. There is no need in reloading `endpoints` and `endpointslices` targets if the referenced `pod` or `service` objects change, since in this case the corresponding `endpoints` and `endpointslices` objects should also change because they contain ResourceVersion of the referenced `pod` or `service` objects, which is modified on object update.

Aliaksandr Valialkin	499594f421	lib/promscrape: allow overriding external_labels as Prometheus does ... Prometheus docs at https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config say: > In communication with external systems, they are always applied only > when a time series does not have a given label yet and are ignored otherwise. Though this may result in consistency chaos when scrape targets override `external_labels`, let's stick with Prometheus behavior for the sake of backwards compatibility. There is last resort in vmagent with `-remoteWrite.label`, which consistently sets the configured labels to all the metrics before sending them to remote storage.
