Aliaksandr Valialkin	9f94c295ab	all: use os.{Read|Write}File instead of ioutil.{Read|Write}File ... The ioutil.{Read|Write}File is deprecated since Go1.16 - see https://tip.golang.org/doc/go1.16#ioutil VictoriaMetrics needs at least Go1.18, so it is safe to remove ioutil usage from source code. This is a follow-up for 02ca2342ab	2022-08-21 23:52:35 +03:00
Roman Khavronenko	d59d829cdb	lib/storage: bump max merge concurrency for small parts to 15 (#2997) ... * lib/storage: bump max merge concurrency for small parts to 15 The change is based on the feedback from users on github. Thier examples show, that limit of 8 sometimes become a bottleneck. Users report that without limit concurrency can climb up to 15-20 merges at once.

Roman Khavronenko	1ee1e986da	lib/storage: limit max mergeConcurrency value for systems with high number of CPUs (#2673) ... Workers count for merges affects the max part size during merges. Such behaviour protects storage from running out of disk space for scenario when all workers are merging parts with the max size. This works very well for most cases. But for systems where high number of CPUs is allocated for vmstorage components this could significantly impact the max part size and result in more unmerged parts than expected. While checking multiple production highly loaded setups it was discovered that `max_over_time(vm_active_merges{type="storage/big}[1h]}"` rarely exceeds 2, and `max_over_time(vm_active_merges{type="storage/small}[1h]}"` rarely exceeds 4. The change in this commit limits the max value for concurrency accordingly. Signed-off-by: hagen1778 <roman@victoriametrics.com>	2022-06-07 14:55:09 +03:00

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).

Do not store in memory the response from the last scrape per each target if -promscrape.noStaleMarkers option is enabled. This should reduce memory usage when the scraped targets return large responses.	2021-10-22 13:10:29 +03:00

Aliaksandr Valialkin	06b0982d6b	lib/promscrape: always initialize http client for stream parsing mode ... Stream parsing mode can be automatically enabled when scraping targets with big response bodies exceeding the -promscrape.minResponseSizeForStreamParse , so it must be always initialized.	2021-10-16 13:18:23 +03:00
Aliaksandr Valialkin	32793adbd9	lib/promscrape: store the last scraped response in compressed form if its size exceeds -promscrape.minResponseSizeForStreamParse ... This should reduce memory usage when scraping targets with big response bodies.	2021-10-16 13:00:30 +03:00
Aliaksandr Valialkin	9866dd95c1	lib/promscrape: store the full response in stream parsing mode in scrapeWork.lastScrape byte slice ... This allows sending staleness marks and properly calculate scrape_series_added metric in stream parsing mode at the cost of the increased memory usage, since now the potentially big response is kept in the lastScrape byte slice per each scrapeWork. In practice the memory usage increase shouldn't be big, since the response size is usually much smaller than the parsed metrics from this response after the relabeling, which usually adds a big pile of target-specific labels per each metric.	2021-10-15 15:39:23 +03:00

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

Aliaksandr Valialkin	d6bd956930	lib/promrelabel: add keep_metrics and drop_metrics actions to relabeling rules ... These actions simlify metrics filtering. For example, - action: keep_metrics regex: 'foo|bar|baz' would leave only metrics with `foo`, `bar` and `baz` names, while the rest of metrics will be deleted. The commit also makes possible to split long regexps into multiple lines. For example, the following config is equivalent to the config above: - action: keep_metrics regex: - foo - bar - baz	2021-09-09 16:18:21 +03:00

Aliaksandr Valialkin	d5622b32e2	lib/promscrape: reduce memory and CPU usage when Prometheus staleness tracking is enabled for metrics from deleted / disappeared scrape targets ... 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	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
