Roman Khavronenko	69d1893f4c	Consul SD - update services on the watcher's start (#2202) ... * lib/discovery/consul: update services on the watcher's start Previously, watcher's start was only initing goroutines for discovery but not waiting for the first iteration to end. It means first Consul discovery wasn't returning discovered targets until the next iteration. The change makes the watcher's start blocking until we get first discovery iteration done and all registries updated.

This should reduce the number of useless entries in the next per-day index, which shouldn't be created there, when the corresponding time series are stopped to be pushed during the current day. - Make the pre-population more smooth in time by using the hash of MetricID instead of MetricID itself when calculating the need for for the given MetricID pre-population. - Sync the logic for pre-population of the next day inverted index with the logic of pre-populating tsid cache after indexdb rotation. This should improve code maintainability.

Roman Khavronenko	cf1a8bce6b	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 00:30:08 +02:00

Aliaksandr Valialkin	46bd2c4d6d	lib/blockcache: increase the lifetime for rarely accessed blocks from 2 minutes to 5 minutes ... This should improve data ingestion speed if time series samples are ingested with interval bigger than 2 minutes. The actual interval could exceed 2 minutes if the original interval between samples doesn't exceed 2 minutes in the case of slow inserts. Slow inserts may appear in the following cases: * Big number of new time series are pushed to VictoriaMetrics, so they couldn't be registered in 2 minutes. * MetricName->tsid cache reset on indexdb rotation or due to unclean shutdown. In this case VictoriaMetrics needs to load MetricName->tsid entries for all the incoming series from IndexDB. IndexDB uses the block cache for increasing lookup performance. If the cache has no the needed block, then IndexDB reads and unpacks the block from disk. This requires an extra disk read IO and CPU. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1401 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2007 This also should increase performance for periodically executed queries with intervals from 2 minutes to 5 minutes. See the previous similar commit - 43103be011 It is possible that the timeout can be increased further.

Aliaksandr Valialkin	f4989edd96	lib/bytesutil: split Resize() into ResizeNoCopy() and ResizeWithCopy() functions ... Previously bytesutil.Resize() was copying the original byte slice contents to a newly allocated slice. This wasted CPU cycles and memory bandwidth in some places, where the original slice contents wasn't needed after slize resizing. Switch such places to bytesutil.ResizeNoCopy(). Rename the original bytesutil.Resize() function to bytesutil.ResizeWithCopy() for the sake of improved readability. Additionally, allocate new slice with `make()` instead of `append()`. This guarantees that the capacity of the allocated slice exactly matches the requested size. The `append()` could return a slice with bigger capacity as an optimization for further `append()` calls. This could result in excess memory usage when the returned byte slice was cached (for instance, in lib/blockcache).

Aliaksandr Valialkin	f3e89754a9	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. The main idea is to perform the calculations on scrape_series_added and series_limit only if the set of metrics exposed by the target has been changed. Scrape targets rarely change the set of exposed metrics, so this optimization should reduce CPU usage in general case.	2021-09-12 12:53:14 +03:00

Store the scraped response body instead of storing the parsed and relabeld metrics. This should reduce memory usage, since the response body takes less memory than the parsed and relabeled metrics. This is especially true for Kubernetes service discovery, which adds many long labels for all the scraped metrics. This should also reduce CPU usage, since the marshaling of the parsed and relabeld metrics has been substituted by response body copying.

Aliaksandr Valialkin	8aa9bba9bd	lib/{mergeset,storage}: switch from sync.Pool to chan-based pool for inmemoryPart objects ... This should reduce memory usage on systems with big number of CPU cores, since every inmemoryPart object occupies at least 64KB of memory and sync.Pool maintains a separate pool inmemoryPart objects per each CPU core. Though the new scheme for the pool worsens per-cpu cache locality, this should be amortized by big sizes of inmemoryPart objects.	2021-07-06 16:28:41 +03:00

Previously the switch from `split` to `whole` mode had been performed too early, e.g. when the current cache size became bigger than 1/4 of the allowed cache size. Now it is performed when the current cache size becomes bigger than 1/2 of the allowed cache size. This change can reduce memory usage for data ingestion path when big number of active time series are ingested.	2021-07-05 15:16:11 +03:00

Aliaksandr Valialkin	aa9b56a046	lib/{mergeset,storage}: reduce the number of fsync calls on data ingestion path on systems with many cpu cores ... VictoriaMetrics maintains a buffer per CPU core for the ingested data. These buffers are flushed to disk every second. These buffers are flushed to disk in parallel starting from the commit 56b6b893ce . This resulted in increased write disk IO usage on systems with many cpu cores as described at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338#issuecomment-863046999 . This commit merges the per-CPU buffers into bigger in-memory buffers before flushing them to disk. This should reduce the rate of fsync syscalls and, consequently, the write disk IO on systems with many CPU cores. This should help https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338 See also https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1244	2021-06-17 13:52:08 +03:00

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 .

Aliaksandr Valialkin	ce9e163e94	lib/httpserver: stop the process on panics in request handlers ... Panics may leave the process in inconsistent state. That's why it is better to stop the process after the panic instead of recovering from the panic. Unfortunately, the standard net/http.Server recovers panics in request handlers. See https://github.com/golang/go/issues/16542 . That's lib/httpserver must stop the process on itself after the panic.	2021-05-03 11:59:40 +03:00
