vmselect processes incoming queries by fetching the requested data from vmstorage nodes configured via -storageNode.

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

  -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)
  -cacheDataPath string
    	Path to directory for cache files and temporary query results. By default, the cache won't be persisted, and temporary query results will be placed under /tmp/searchResults. If set, the cache will be persisted under cacheDataPath/rollupResult, and temporary query results will be placed under cacheDataPath/tmp/searchResults.
  -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)
  -clusternative.disableCompression
    	Whether to disable compression of the data sent to vmselect via -clusternativeListenAddr. This reduces CPU usage at the cost of higher network bandwidth usage
  -clusternative.maxConcurrentRequests int
    	The maximum number of concurrent vmselect requests the server can process at -clusternativeListenAddr. Default value depends on the number of available CPU cores. It shouldn't be high, since a single request usually saturates a CPU core at the underlying vmstorage nodes, and many concurrently executed requests may require high amounts of memory. See also -clusternative.maxQueueDuration (default 128 = 2*cgroup.AvailableCPUs())
  -clusternative.maxQueueDuration duration
    	The maximum time the incoming query to -clusternativeListenAddr waits for execution when -clusternative.maxConcurrentRequests limit is reached (default 10s)
  -clusternative.maxTagKeys int
    	The maximum number of tag keys returned per search at -clusternativeListenAddr (default 100000)
  -clusternative.maxTagValueSuffixesPerSearch int
    	The maximum number of tag value suffixes returned from /metrics/find at -clusternativeListenAddr (default 100000)
  -clusternative.maxTagValues int
    	The maximum number of tag values returned per search at -clusternativeListenAddr (default 100000)
  -clusternativeListenAddr string
    	TCP address to listen for requests from other vmselect nodes in multi-level cluster setup. See https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#multi-level-cluster-setup . Usually :8401 should be set to match default vmstorage port for vmselect. Disabled work if empty
  -dedup.minScrapeInterval duration
    	Leave only the last sample in every time series per each discrete interval equal to -dedup.minScrapeInterval > 0. See https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#deduplication for details
  -deleteAuthKey value
    	authKey for metrics' deletion via /prometheus/api/v1/admin/tsdb/delete_series and /graphite/tags/delSeries. It could be passed via authKey query arg. It overrides -httpAuth.*
    	Flag value can be read from the given file when using -deleteAuthKey=file:///abs/path/to/file or -deleteAuthKey=file://./relative/path/to/file.
    	Flag value can be read from the given http/https url when using -deleteAuthKey=http://host/path or -deleteAuthKey=https://host/path
  -denyQueryTracing
    	Whether to disable the ability to trace queries. See https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#query-tracing

    	Whether to enable metadata processing for metrics scraped from targets, received via VictoriaMetrics remote write, Prometheus remote write v1 or OpenTelemetry protocol. See also remoteWrite.maxMetadataPerBlock (default true)
  -enableMultitenancyViaHeaders
    	Enables multitenancy via HTTP headers. See https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#multitenancy-via-headers (default true)
  -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.disableAdviseRandomRead
    	Whether to disable FADV_RANDOM and MADV_RANDOM hints for data part files. Typical queries with selectors access data part files at random offsets, so FADV_RANDOM is enforced to reduce excessive disk readahead.Use this flag if your query read pattern benefits from sequential read (e.g. query by metric name without selectors) to prefer FADV_NORMAL. (default true)
  -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 256 = 16x CPU cores, capped at 256)
  -globalReplicationFactor int
    	How many copies of every ingested sample is available across vmstorage groups. vmselect continues returning full responses when up to globalReplicationFactor-1 vmstorage groups are temporarily unavailable.

  -healthcheck
    	Whether to check that the running process accepts connections at -httpListenAddr and exit. The exit code is non-zero if the check fails. This is useful for Docker HEALTHCHECK in images without curl or wget. Pass the same -httpListenAddr as the checked process has
  -http.connTimeout duration

    	Disable CORS for all origins (*)
  -http.disableKeepAlive
    	Whether to disable HTTP keep-alive for incoming connections at -httpListenAddr

  -http.idleConnTimeout duration
    	Timeout for incoming idle http connections (default 1m0s)
  -http.maxGracefulShutdownDuration duration
    	The maximum duration for a graceful shutdown of the HTTP server. During this period the server stops accepting new connections, but it will continue serving existing connections. The remaining in-flight requests are canceled before the deadline, so the shutdown can finish within this duration. A highly loaded server may require increased value for a graceful shutdown (default 7s)
  -http.pathPrefix string
    	An optional prefix to add to all the paths handled by http server. For example, if '-http.pathPrefix=/foo/bar' is set, then all the http requests will be handled on '/foo/bar/*' paths. This may be useful for proxied requests. See https://www.robustperception.io/using-external-urls-and-proxies-with-prometheus
  -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
  -httpAuth.password value
    	Password for HTTP server's Basic Auth. The authentication is disabled if -httpAuth.username is empty

  -maxConcurrentInserts int
    	The maximum number of concurrent insert requests. Set higher value when clients send data over slow networks. Default value depends on the number of available CPU cores. It should work fine in most cases since it minimizes resource usage. See also -insert.maxQueueDuration (default 128 = 2x CPU cores)
  -memory.allowedBytes size
    	Allowed size of system memory VictoriaMetrics caches may occupy. This option overrides -memory.allowedPercent if set to a non-zero value. Too low a value may increase the cache miss rate usually resulting in higher CPU and disk IO usage. Too high a value may evict too much data from the OS page cache resulting in higher disk IO usage.
