  -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)
  -configAuthKey value
     Authorization key for accessing /config page. It must be passed via authKey query arg. It overrides -httpAuth.*

     Flag value can be read from the given http/https url when using -configAuthKey=http://host/path or -configAuthKey=https://host/path
  -csvTrimTimestamp duration
     Trim timestamps when importing csv data to this duration. Minimum practical duration is 1ms. Higher duration (i.e. 1s) may be used for reducing disk space usage for timestamp data (default 1ms)

  -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
  -dryRun

  -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

  -http.shutdownDelay duration
     Optional delay before http server shutdown. During this delay, the server returns non-OK responses from /health page, so load balancers can route new requests to other servers

  -inmemoryDataFlushInterval duration
     The interval for guaranteed saving of in-memory data to disk. The saved data survives unclean shutdowns such as OOM crash, hardware reset, SIGKILL, etc. Bigger intervals may help increase the lifetime of flash storage with limited write cycles (e.g. Raspberry PI).
