Aliaksandr Valialkin	faad6f84a4	lib/storage: return back filter arg to getMetricIDsForTagFilter function ... The filter arg has been removed in the commit c7ee2fabb8 because it was preventing from caching the number of matching time series per each tf. Now the cache contains duration for tf execution, so the filter shouldn't break such caching.	2021-02-17 19:33:22 +02:00
Aliaksandr Valialkin	d4849561ef	app/vmstorage: export vm_composite_filter_success_conversions_total and vm_composite_filter_missing_conversions_total metrics	2021-02-17 19:13:38 +02:00

This could result in missing time series for such tag filters.	2021-02-14 23:38:14 +02:00
Aliaksandr Valialkin	80dc74dbc1	lib/promscrape: remove vm_promscrape_scrapes_failed_per_url_total and vm_promscrape_scrapes_skipped_by_sample_limit_per_url_total metrics ... These metrics may result in big number of time series when vmagent scrapes thousands of targets and these targets constantly changes. * It is better using `up == 0` query for determining failing targets. * It is better using the following query for determining targets with exceeded limit on the number of metrics: scrape_samples_scraped > 0 if up == 0	2021-02-12 05:26:04 +02:00
Aliaksandr Valialkin	0e26b7168a	lib/storage: return back in-order applying of tag filters, since concurrently executing tag filters can result in CPU and RAM waste in common case	2021-02-10 22:41:04 +02:00
Aliaksandr Valialkin	b51c23dc5b	lib/storage: parallelize tag filters execution a bit ... This should reduce execution time when a query contains multiple tag filters and each such filter matches big number of time series.	2021-02-10 18:12:25 +02:00
Aliaksandr Valialkin	c7ee2fabb8	lib/storage: remove filter arg from getMetricIDsForDateTagFilter function ... The `filter` arg breaks the logic for sorting tag filters by the matching metrics, which may result in non-optimal performance during time series search.	2021-02-10 18:12:20 +02:00

Aliaksandr Valialkin	d455764a6f	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.

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

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	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

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.

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.

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
