Aliaksandr Valialkin	fd7dd5064a	lib/storage: code cleanup after 10f2eedee0 ... Remove the code that uses metricIDs caches for the current and the previous hour during metricIDs search, since this code became unused after implementing per-day inverted index almost a year ago.

Aliaksandr Valialkin	3ad7566a87	lib/storage: imrpove cache effectiveness for time series ids matching the given filters ... Previously the maximum cache lifetime has been limited by 10 seconds.

Aliaksandr Valialkin	00ec2b7189	lib/protoparser: use all the available CPU cores for processing ingested data from a single /api/v1/import stream ... Previously a single data ingestion stream to /api/v1/import could load only a single CPU core.	2020-09-26 04:22:06 +03:00
Aliaksandr Valialkin	533bf76a12	lib/storage: correctly use maxBlockSize in various checks ... Previously `maxBlockSize` has been multiplied by 8 in certain checks. This is unnecessary.	2020-09-24 18:13:15 +03:00

Aliaksandr Valialkin	9705ac5d7a	lib/persistentqueue: code simplification after d455764a6f	2020-09-16 21:14:01 +03:00
Aliaksandr Valialkin	eee6f1e56d	lib/persistentqueue: make the persistent queue more durable against unclean shutdown (kill -9, OOM, hard reset) ... The strategy is: - Periodical flushing of inmemory blocks to files, so they aren't lost on unclean shutdown. - Periodical syncing of metadata for persisted queues, so the metadata remains in sync with the persisted data. - Automatic adjusting of too big chunk size when opening the queue. The chunk size may be bigger than the writer offset after unclean shutdown. - Skipping of broken chunk file if it cannot be read. - Fsyncing finalized chunk files. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/687	2020-09-16 18:13:24 +03:00

Aliaksandr Valialkin	cd87ca303f	lib/protoparser: report more errors for incorrect timestamps and/or values ... Previously certain errors in timestamps and/or values could be silently skipped, which could lead to samples with zero values stored in the database.

Aliaksandr Valialkin	114cf24b43	lib/promscrape/discovery/dns: add __meta_dns_srv_record_target and __meta_dns_srv_record_port labels ... This syncs dns service discovery with Prometheus 2.21 - see https://github.com/prometheus/prometheus/releases and https://github.com/prometheus/prometheus/pull/7678 .	2020-09-11 21:35:39 +03:00
Aliaksandr Valialkin	5cf5a0e8c4	lib/protoparser/common: do not read request body when parsing timestamp query arg ... This was preventing from reading data via /api/v1/prometheus/import . Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/750	2020-09-11 14:45:21 +03:00

Aliaksandr Valialkin	8bd5aa3516	lib/protoparser: accept timestamp in milliseconds instead of seconds at /api/v1/import/prometheus ... This improves consistency with timestamps in Prometheus text exposition format	2020-09-11 14:05:24 +03:00
Aliaksandr Valialkin	58d3b82ae5	app/{vminsert,vmagent}: allow passing timestamp via timestamp query arg when ingesting data to /api/v1/import/prometheus ... See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/750	2020-09-11 13:28:31 +03:00
Nikolay Khramchikhin	af994562c8	Added endpointslices discovery to k8s api (#760) ... This is similar to https://github.com/prometheus/prometheus/pull/6838 , which will be added in Prometheus v2.21. See https://github.com/prometheus/prometheus/releases/tag/v2.21.0-rc.1 * Added endpointslices discovery to k8s api Started from 1.17 k8s version endpointslices is beta, it allows to query k8s api for endpoints more efficient. It presents at scrape_config.yaml as separate role for kubernetes_sd_config. kubernetes_sd_config: - role: endpointslices * fixed typos, changed EndpointConditions signature - with values instead of pointers	2020-09-11 12:24:50 +03:00
Aliaksandr Valialkin	f307e6f432	app/vmselect: initial implementation of Graphite Metrics API ... See https://graphite-api.readthedocs.io/en/latest/api.html#the-metrics-api	2020-09-11 00:30:20 +03:00
Aliaksandr Valialkin	f5cb213ef9	lib/storage: reuse timestamp blocks for adjancent metric blocks with identical timestamps ... This should reduce disk space usage when scraping targets containing metrics with identical names such as `node_cpu_seconds_total`, histograms, quantiles, etc. Expose `vm_timestamps_blocks_merged_total` and `vm_timestamps_bytes_saved_total` metrics for monitoring the effectiveness of timestamp blocks merging.	2020-09-09 23:59:21 +03:00
Aliaksandr Valialkin	e5c8377212	lib/httpserver: add a jitter to connection timeouts in order to protect from Thundering herd problem	2020-09-08 19:57:20 +03:00
Nikolay Khramchikhin	fb356c434b	Changed s3 configProfile flag default, (#749) ... aws sdk has complicated logic for chosing profile name and we shouldn't set it to `default` value.

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/719	2020-09-02 19:47:02 +03:00
Aliaksandr Valialkin	95ce89e7d7	lib/promscrape: use the number of parsed rows as a basis for writeRequestCtxPool leveling ... The previous basis on `cap(sw.labels)` doesn't work anymore after 7785869ccc , because `sw.labels` may be reset multiple times when processing big number of rows.	2020-09-02 18:46:55 +03:00
Aliaksandr Valialkin	bc1ca4b20b	lib/httpserver: add -http.idleConnTimeout command-line flag for tuning the timeout for incoming idle http connections	2020-09-01 15:33:31 +03:00

Aliaksandr Valialkin	5f2277624a	lib/{promscrape,leveledbytebufferpool}: rename getPoolIdAndCapacity to getPoolIDAndCapacity in order to make golint happy	2020-08-28 09:49:22 +03:00

Roman Khavronenko	34ef10fbcc	lib/flagutil: avoid int overflow for arch 386 (#710) ... Arch 386 is a 32-bit architecture and interprets int type for numbers as an explicit int32, whereas on most modern CPUs int is implicitly an int64. This makes tests to fail with `int overflow` error.	2020-08-28 09:46:35 +03:00
Aliaksandr Valialkin	9a77ae9d1c	lib/promscrape: reduce memory usage when scraping targets with big number of metrics alongside targets with small number of labels ... Previously targets with big number of metrics and/or labels could generated too big buffers, which then could be re-used when scraping targets with small number of metrics. This resulted in memory waste. Now big buffers are used only for targets with big number of metrics / labels, while small buffers are used for targets with small number of metrics / labels.	2020-08-16 22:30:34 +03:00
Aliaksandr Valialkin	3ea6444219	lib/leveledbytebufferpool: allocate byte buffers with capacity rounded to the upper boundary for the given bucket ... This should reduce the number of resizings for the returned byte buffers.	2020-08-16 22:13:38 +03:00

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.
