156b4c2490 vendor: update github.com/VictoriaMetrics/metrics from v1.16.0 to v1.17.0 2021-03-17 23:22:40 +02:00

93a318d1bf vendor: update github.com/VictoriaMetrics/metrics from v1.15.3 to v1.16.0
This adds the following new metrics for each VictoriaMetrics app:

* process_resident_memory_anonymous_bytes - the RSS share for memory allocated by the process itself.
  This share cannot be freed by the OS, so it must be taken into account by OOM killer.

* process_resident_memory_pagecache_bytes - the RSS share for page cache memory (aka memory-mapped files).
  This share can be freed by the OS at any time, so it must be ignored by OOM killer.

265ac5f695 docs/CHANGELOG.md: do not mention reduction in query duration
There was a signficant refactoring in the code responsible for time series search,
so it can result in both speed ups and slow downs depending on used queries.

727ded9d4e lib/storage: time series search optimization according to production workload profiling
Do not pass filter metric ids to getMetricIDsForTagFilter, since it has been appeared that this slows down
the function by multiple times when it finds big number of metricIDs (tens of millions).

7f52aae20c lib/promscrape: an attempt to reduce memory usage when vmagent scrapes targets with varying number of metrics
Do not cache too big byte buffers and too big writeRequestCtx objects,
