Vmstorage Common Flags

vmstorage stores time series data obtained from vminsert and returns the requested data to vmselect.

See the docs at https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/ .

  -bigMergeConcurrency int
     Deprecated: this flag does nothing
  -blockcache.missesBeforeCaching int
     The number of cache misses before putting the block into cache. Higher values may reduce indexdb/dataBlocks cache size at the cost of higher CPU and disk read usage (default 2)
  -cacheExpireDuration duration
     Items are removed from in-memory caches after they aren't accessed for this duration. Lower values may reduce memory usage at the cost of higher CPU usage. See also -prevCacheRemovalPercent (default 30m0s)
  -dedup.minScrapeInterval duration
     Leave only the last sample in every time series per each discrete interval equal to -dedup.minScrapeInterval > 0. See also -streamAggr.dedupInterval and https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#deduplication
  -denyQueriesOutsideRetention
     Whether to deny queries outside the configured -retentionPeriod and -futureRetention. When set, then /api/v1/query_range will return an error for queries with 'from' value outside -retentionPeriod or 'to' value beyond -futureRetention. This may be useful when multiple data sources with distinct retentions are hidden behind query-tee
  -denyQueryTracing
     Whether to disable the ability to trace queries. See https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#query-tracing
  -disablePerDayIndex
     Disable per-day index and use global index for all searches. This may improve performance and decrease disk space usage for the use cases with fixed set of timeseries scattered across a big time range (for example, when loading years of historical data). See https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#index-tuning
  -enableTCP6
     Whether to enable IPv6 for listening and dialing. By default, only IPv4 TCP and UDP are used
  -envflag.enable
     Whether to enable reading flags from environment variables in addition to the command line. Command line flag values have priority over values from environment vars. Flags are read only from the command line if this flag isn't set. See https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#environment-variables for more details
  -envflag.prefix string
     Prefix for environment variables if -envflag.enable is set
  -filestream.disableFadvise
     Whether to disable fadvise() syscall when reading large data files. The fadvise() syscall prevents from eviction of recently accessed data from OS page cache during background merges and backups. In some rare cases it is better to disable the syscall if it uses too much CPU

  -fs.disableMincore
     Whether to disable the mincore() syscall for checking mmap()ed files. By default, mincore() is used to detect whether mmap()ed file pages are resident in memory. Disabling mincore() may be needed on older ZFS filesystems (below 2.1.5), since it may trigger ZFS bug. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10327 for details.
  -fs.disableMmap
     Whether to use pread() instead of mmap() for reading data files. By default, mmap() is used for 64-bit arches and pread() is used for 32-bit arches, since they cannot read data files bigger than 2^32 bytes in memory. mmap() is usually faster for reading small data chunks than pread()
  -fs.maxConcurrency int
     The maximum number of concurrent goroutines to work with files; smaller values may help reducing Go scheduling latency on systems with small number of CPU cores; higher values may help reducing data ingestion latency on systems with high-latency storage such as NFS or Ceph (default fsutil.getDefaultConcurrency())
