This metric is very similar to `vmagent_remotewrite_pending_data_bytes` except of accounting for bytes in-memory.	2020-07-13 21:54:54 +03:00
Roman Khavronenko	a02097e657	Extend metric vm_promscrape_targets with status label (#615) ... The change to `vm_promscrape_targets` metric suppose to improve observability for `vmagent` so it will be possible to track how many targets are up or down for every specific scrape group: ``` vm_promscrape_targets{type="static_configs", status="down"} 1 vm_promscrape_targets{type="static_configs", status="up"} 2 ```	2020-07-13 21:54:53 +03:00
Aliaksandr Valialkin	6373d377ef	app/{vminsert,vmagent}: add ability to import data in Prometheus exposition format via /api/v1/import/prometheus	2020-07-10 12:13:28 +03:00

Aliaksandr Valialkin	87f8c728bf	lib/promscrape: send Accept header similar to Prometheus when scraping targets ... This should fix scraping Spring Boot servers, which return incorrect response unless `Accept: text/plain` request header is set. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/608	2020-07-08 19:50:06 +03:00
Aliaksandr Valialkin	7335743d57	lib/storage: limit the maximum concurrency for data ingestion to GOMAXPROCS ... Previously the concurrency has been limited to GOMAXPROCS*2. This had little sense, since every call to Storage.AddRows is bound to CPU, so the maximum ingestion bandwidth is achieved when the number of concurrent calls to Storage.AddRows is limited to the number of CPUs, i.e. to GOMAXPROCS.	2020-07-08 17:34:27 +03:00
Roman Khavronenko	929ad74de6	lib/protoparser: fix metric name of unmarshal errors in promremotewrite (#607) ... The change fixes the typo in metric name `vm_protoparser_unmarshal_errors` to respect the naming standard.	2020-07-08 14:19:27 +03:00

Aliaksandr Valialkin	fe58462bef	lib/storage: reset MetricName->TSID cache after deleting time series ... This should prevent from adding new data points to deleted time series without the need to check for the deleted time series. This improves ingestion performance a bit when the `deleted time series ids` aka `dmis` set contains big number of time series. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/596 Based on the idea from @n4mine at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/604	2020-07-06 22:01:24 +03:00

Aliaksandr Valialkin	0bff96fe4b	lib/storage: prioritize data ingestion over heavy queries ... Heavy queries could result in the lack of CPU resources for processing the current data ingestion stream. Prevent this by delaying queries' execution until free resources are available for data ingestion. Expose `vm_search_delays_total` metric, which may be used in for alerting when there is no enough CPU resources for data ingestion and/or for executing heavy queries.

Aliaksandr Valialkin	ee03b4ccbd	lib/promscrape: prevent from too big deadline misses on scrape retries ... The maximum deadline miss duration is reduced to 2x scrape_interval in the worst case. By default it is limited to scrape_interval configured for the given scrape target.	2020-07-03 20:42:09 +03:00

Aliaksandr Valialkin	3a444bb7bb	lib/promrelabel: add support for keep_if_equal and drop_if_equal actions to relabel configs ... These actions may be useful for filtering out unneeded targets and/or metrics if they contain equal label values. For example, the following rule would leave the target only if __meta_kubernetes_annotation_prometheus_io_port equals __meta_kubernetes_pod_container_port_number: - action: keep_if_equal source_labels: [__meta_kubernetes_annotation_prometheus_io_port, __meta_kubernetes_pod_container_port_number]	2020-06-23 17:29:19 +03:00

Use this index during search for filters like `__name__=~"foo\\.[^.]*\\.bar\\.baz"` which end with non-empty suffix with dots, i.e. `.bar.baz` in this case. This change may "hide" historical time series during queries. The workaround is to add `[.]*` to the end of regexp label filter, i.e. "foo\\.[^.]*\\.bar\\.baz" should be substituted with "foo\\.[^.]*\\.bar\\.baz[.]*".	2020-05-27 21:48:08 +03:00
