Aliaksandr Valialkin	5e71fab8a6	lib/storage: reduce the maximum number of concurrent merge workers to GOMAXPROCS/2 ... Previously the limit has been raised to GOMAXPROCS, but it has been appeared that this increases query latencies since more CPUs are busy with merges. While at it, substitute `*MergeConcurrencyLimitCh` channels with simple integer limits.	2020-07-31 17:46:56 +03:00
Aliaksandr Valialkin	e7959094f6	lib/storage: remove prioritizing of merging small parts over merging big parts, since it doesn't work as expected ... The prioritizing could lead to big merge starvation, which could end up in too big number of parts that must be merged into big parts. Multiple big merges may be initiated after the migration from v1.39.0 or v1.39.1. It is OK - these merges should be finished soon, which should return CPU and disk IO usage to normal levels. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/648 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/618	2020-07-30 19:57:27 +03:00
Aliaksandr Valialkin	922d9aadf2	lib/storage: properly update vm_slow_row_inserts_total metric when importing multiple data points per time series at once ...

Aliaksandr Valialkin	e4303d3d21	lib/storage: prevent possible race condition when all the goroutines exit Storage.AddRows, before goroutines other goroutines are blocked on searchTSIDsCond inside Storage.searchTSIDs ... This condition may occur after the following sequence of events: 1) A goroutine enters the loop body when len(addRowsConcurrencyCh) == cap(addRowsConcurrencyCh) inside Storage.searchTSIDs. 2) All the goroutines return from Storage.AddRows. 3) The goroutine from step 1 blocks on searchTSIDsCond.Wait() inside the loop body. The goroutine remains blocked until the next call to Storage.AddRows, which calls searchTSIDsCond.Signal(). This may take indefinite time.	2020-07-22 21:52:34 +03:00
Aliaksandr Valialkin	31ae5911a8	app/vmagent: add -remoteWrite.decimalPlaces command-line flag, which may be used for reducing disk space usage on the remote storage	2020-07-21 21:55:32 +03:00

Aliaksandr Valialkin	e1107fec10	lib/storage: reset MetricName->TSID cache after marking metricIDs as deleted ... This is a follow-up commit after 12b16077c4 , which didn't reset the `tsidCache` in all the required places. This could result in indefinite errors like: missing metricName by metricID ...; this could be the case after unclean shutdown; deleting the metricID, so it could be re-created next time Fix this by resetting the cache inside deleteMetricIDs function.	2020-07-14 14:06:32 +03:00
Aliaksandr Valialkin	cde18d1f43	lib/protoparser: properly update vm_protoparser_rows_read_total{type="promscrape"} metric	2020-07-14 12:16:35 +03:00
Seva Poliakov	457e61900d	add vm_protoparser_rows_read_total metrics to promscrape (#624) ... * add vm_protoparser_rows_read_total metrics to promscrape move vm_protoparser_rows_read_total for promscrape to better place move vm_protoparser_rows_read_total for promscrape to better place * remove possibility of infinity loop at prometheus parser	2020-07-14 12:16:34 +03:00
Roman Khavronenko	7e347972c4	lib/flagutil: specify additional description for all Array type flags (#620) ... Array type flag is now defined as `value` type in flag description when printed. This change adds additional description to every Array type flag so it would be clear what exact type is used: ``` -remoteWrite.urlRelabelConfig array Optional path to relabel config for the corresponding -remoteWrite.url Supports array of values separated by comma or specified via multiple flags. ```	2020-07-13 21:56:37 +03:00
Roman Khavronenko	19dd121968	lib/persistentqueue: add vm_persistentqueue_bytes_pending metric (#619) ... Metric `vm_persistentqueue_bytes_pending` is a gauge that shows current amount of bytes in persistentqueue flushed on disk as a difference between write and read offsets. This metric is very similar to `vmagent_remotewrite_pending_data_bytes` except of accounting for bytes in-memory.	2020-07-13 21:54:09 +03:00
Roman Khavronenko	829ec4f9cf	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 21:52:03 +03:00

Aliaksandr Valialkin	3e1d7d8489	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 19:48:22 +03:00
Aliaksandr Valialkin	cb92113632	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 17:32:18 +03:00
Roman Khavronenko	e7557e0252	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 14:18:41 +03:00

Aliaksandr Valialkin	12b16077c4	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 22:01:08 +03:00

Aliaksandr Valialkin	6daa5f7500	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. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/291	2020-07-05 19:42:05 +03:00
Aliaksandr Valialkin	ff6a0955eb	lib/promscrape: use HostClient.DoDeadline instead of HostClient.Do in order to guarantee strict deadline across multiple scrape attempts	2020-07-03 21:33:22 +03:00
Aliaksandr Valialkin	8b133e40d5	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 20:41:36 +03:00

Aliaksandr Valialkin	d186472081	lib/storage: improve search speed for time series matching Graphite whildcards such as foo.*.bar.baz ... Add index for reverse Graphite-like metric names with dots. 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 21:45:52 +03:00

Aliaksandr Valialkin	4c02e496f7	lib/fs: do not postpone directory removal on NFS error ... Continue trying to remove NFS directory on temporary errors for up to a minute. The previous async removal process breaks in the following case during VictoriaMetrics start - VictoriaMetrics opens index, finds incomplete merge transactions and starts replaying them. - The transaction instructs removing old directories for parts, which were already merged into bigger part. - VictoriaMetrics removes these directories, but their removal is delayed due to NFS errors. - VictoriaMetrics scans partition directory after all the incomplete merge transactions are finished and finds directories, which should be removed, but weren't still removed due to NFS errors. - VictoriaMetrics panics when it finds unexpected empty directory.
