Aliaksandr Valialkin	4f8a3af061	lib/protoparser/promremotewrite: synchronously process Prometheus remote_write requests ... There is no reason in processing these requests asynchronously in the face of https://github.com/VictoriaMetrics/VictoriaMetrics/issues/896 Synchronous processing code is easier to read and understand than the previous async code	2020-11-13 12:17:25 +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.

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 ...

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.
