See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2825 and https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2831 Signed-off-by: hagen1778 <roman@victoriametrics.com>	2022-07-06 10:47:51 +02:00
Aliaksandr Valialkin	78f9a8aafd	lib/storage: put the (date, metricID) entry in dateMetricIDCache just after the corresponding series is registered in the per-day inverted index ... Previously the time series could be put into dateMetricIDCache without registering in the per-day inverted index if GetOrCreateTSIDByName finds TSID entry in the global index. This could lead to missing series in query results. The issue has been introduced in the commit 55e7afae3a, which has been included in VictoriaMetrics v1.78.0	2022-07-05 14:56:55 +03:00

Aliaksandr Valialkin	7d5d33fd71	lib/storage: return marshaled metric names from SearchMetricNames ... Previously SearchMetricNames was returning unmarshaled metric names. This wasn't great for vmstorage, which should spend additional CPU time for marshaling the metric names before sending them to vmselect. While at it, remove possible duplicate metric names, which could occur when multiple samples for new time series are ingested via concurrent requests. Also sort the metric names before returning them to the client. This simplifies debugging of the returned metric names across repeated requests to /api/v1/series	2022-06-28 18:16:32 +03:00

Aliaksandr Valialkin	94b81165d0	all: limit the maximum memory usage for regexp cache, which stores parsed regular expressions in MetricsQL queries ... Previously the cache could store 10K unique regexps. When every regexp is huge (e.g. hundreds of kilobytes), then the total cache size could grow to multiples of gigabytes. Now the cache size is limited by the total length of all cached regexps. So huge regexps won't result in high memory usage for the cache.	2022-06-24 17:58:47 +03:00
hagen1778	e40d015e9a	vmselect: make vm_partial_results_total consistent ... Metrics `vm_partial_results_total` and `vm_requests_total` serving the similar purpose, but contain inconsistent set of labels. This change updates `vm_partial_results_total` labels to be consistent with `vm_requests_total`. The change breaks backward compatibility with assumption that `vm_partial_results_total` wasn't widely used, since it is not documented and absent in the alerts and dashboards.

Aliaksandr Valialkin	a1629bd3be	lib/netutil.ConnPool: skip dialing remote address if the previous dial attempt was unsuccessful ... If the previous dial attempt was unsuccessful, then all the new dial attempts are skipped until the background goroutine determines that the given address can be successfully dialed. This reduces query latency when some of vmstorage nodes are unavailable and dialing them is slow. This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/711 This commit is based on ideas from the https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2756 The main differences are: - The check for healthy/unhealthy storage nodes is moved one level lower from app/vmselect/netstorage to lib/netutil.ConnPool. This makes possible re-using this feature everywhere lib/netutil.ConnPool is used. - The check doesn't take into account handshake errors for already established connections. Handshake errors usually mean improperly configured VictoriaMetrics cluster, so they shouldn't be ignored.	2022-06-20 17:33:54 +03:00

The same limit is applied for the ingested data, so no reason to allow to request data in future far than that. The change is also needed for corner cases like https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2669 where too high `end` value triggers inefficient global index search.

Roman Khavronenko	87e4e76537	vmalert: support /rules path for Grafana's ngalert requests (#2593) ... Unexpectedly, Grafana makes an extra request to `/rules` handler in addition to `/api/v1/rules` calls in alerts UI. This happens only for Grafana versions older than 8.5.*. Apparently, this is related to support of other monitoring systems. Prometheus responds with `text/html` content for UI page `/rules` to such requests. Actually, returning just a blank page with SC=200 works as well. Returning actual response of `/api/v1/rules` results in error in Grafana since it expects a `yaml` (?) in response.

Roman Khavronenko	d107f86fbc	lib/index: reduce read/write load after indexDB rotation (#2177) ... * lib/index: reduce read/write load after indexDB rotation IndexDB in VM is responsible for storing TSID - ID's used for identifying time series. The index is stored on disk and used by both ingestion and read path. IndexDB is stored separately to data parts and is global for all stored data. It can't be deleted partially as VM deletes data parts. Instead, indexDB is rotated once in `retention` interval. The rotation procedure means that `current` indexDB becomes `previous`, and new freshly created indexDB struct becomes `current`. So in any time, VM holds indexDB for current and previous retention periods. When time series is ingested or queried, VM checks if its TSID is present in `current` indexDB. If it is missing, it checks the `previous` indexDB. If TSID was found, it gets copied to the `current` indexDB. In this way `current` indexDB stores only series which were active during the retention period. To improve indexDB lookups, VM uses a cache layer called `tsidCache`. Both write and read path consult `tsidCache` and on miss the relad lookup happens. When rotation happens, VM resets the `tsidCache`. This is needed for ingestion path to trigger `current` indexDB re-population. Since index re-population requires additional resources, every index rotation event may cause some extra load on CPU and disk. While it may be unnoticeable for most of the cases, for systems with very high number of unique series each rotation may lead to performance degradation for some period of time. This PR makes an attempt to smooth out resource usage after the rotation. The changes are following: 1. `tsidCache` is no longer reset after the rotation; 2. Instead, each entry in `tsidCache` gains a notion of indexDB to which they belong; 3. On ingestion path after the rotation we check if requested TSID was found in `tsidCache`. Then we have 3 branches: 3.1 Fast path. It was found, and belongs to the `current` indexDB. Return TSID. 3.2 Slow path. It wasn't found, so we generate it from scratch, add to `current` indexDB, add it to `tsidCache`. 3.3 Smooth path. It was found but does not belong to the `current` indexDB. In this case, we add it to the `current` indexDB with some probability. The probability is based on time passed since the last rotation with some threshold. The more time has passed since rotation the higher is chance to re-populate `current` indexDB. The default re-population interval in this PR is set to `1h`, during which entries from `previous` index supposed to slowly re-populate `current` index. The new metric `vm_timeseries_repopulated_total` was added to identify how many TSIDs were moved from `previous` indexDB to the `current` indexDB. This metric supposed to grow only during the first `1h` after the last rotation. https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1401 Signed-off-by: hagen1778 <roman@victoriametrics.com> * wip * wip Co-authored-by: Aliaksandr Valialkin <valyala@victoriametrics.com>	2022-02-12 00:34:44 +02:00

Aliaksandr Valialkin	09670479cd	lib/promscrape: reduce CPU usage for common case when calculating scrape_series_added metric ... Also reduce CPU usage when applying `series_limit` to scrape targets with constant set of metrics.

This makes consitent the list of deleted metricIDs when it is used from both the current indexDB and the previous indexDB (aka extDB). This should fix the issue, which could lead to storing new samples under deleted metricIDs after indexDB rotation. See more details at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1347#issuecomment-861232136 . Thanks to @tangqipengleoo for the initial analysis and the pull request - https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 . This commit resolves the issue in more generic way compared to https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 .

For those docs which are copied from internal packages `sort` is added via makefile command. For the rest it is added manually since they're updated manually as well. The rest of changes is connected with markdown formatting. For example, changing headers in some files (`##` => `#`) makes navigation on .github.io to look better. This especially useful for `changelog` docs. Table of contents for `vmctl` is dropped, since we already have it autogenerated on .github.io. No link changes expected.
