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
  -enableIngestionAPI
    	Whether to enable ingestion APIs on vmstorage HTTP listener. Currently enables Prometheus remote write v1 at /insert/<accountID>/prometheus and /insert/<accountID>/prometheus/api/v1/write
  -enableMetadata
    	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)
  -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
  -finalMergeDelay duration
    	Deprecated: this flag does nothing
  -flagsAuthKey value
    	Auth key for /flags endpoint. It must be passed via authKey query arg. It overrides -httpAuth.*
    	Flag value can be read from the given file when using -flagsAuthKey=file:///abs/path/to/file or -flagsAuthKey=file://./relative/path/to/file.
    	Flag value can be read from the given http/https url when using -flagsAuthKey=http://host/path or -flagsAuthKey=https://host/path
  -forceFlushAuthKey value
    	authKey, which must be passed in query string to /internal/force_flush pages. It overrides -httpAuth.*

    	Flag value can be read from the given http/https url when using -forceMergeAuthKey=http://host/path or -forceMergeAuthKey=https://host/path
  -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)
  -futureRetention value
    	Data with timestamps bigger than now+futureRetention is automatically deleted. The minimum futureRetention is 2 days. See https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#retention

    	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
    	Flag value can be read from the given file when using -httpAuth.password=file:///abs/path/to/file or -httpAuth.password=file://./relative/path/to/file.

    	Supports array of values separated by comma or specified via multiple flags.
    	Empty values are set to false.
  -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).

    	Output for the logs. Supported values: stderr, stdout (default "stderr")
  -loggerTimezone string
    	Timezone to use for timestamps in logs. Timezone must be a valid IANA Time Zone. For example: America/New_York, Europe/Berlin, Etc/GMT+3 or Local (default "UTC")
  -loggerWarnsPerSecondLimit int
    	Per-second limit on the number of WARN messages. If more than the given number of warns are emitted per second, then the remaining warns are suppressed. Zero values disable the rate limit
  -maxBackfillAge value
    	The maximum allowed age for the ingested samples with historical timestamps. Samples with timestamps older than now-maxBackfillAge are rejected during data ingestion. By default, or when set to 0, -maxBackfillAge equals to -retentionPeriod, e.g. it is unlimited within the configured retention. This can be useful for limiting ingestion of historical samples, for example, when older data has been moved to another storage tier.

    	Supports the following optional suffixes for size values: KB, MB, GB, TB, KiB, MiB, GiB, TiB (default 100000000)
  -storage.trackMetricNamesStats
    	Whether to track ingest and query requests for timeseries metric names. This feature allows to track metric names unused at query requests. See https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#track-ingested-metrics-usage (default true)
  -storage.vminsertConnsShutdownDuration duration
    	The time needed for gradual closing of vminsert connections during graceful shutdown. Bigger duration reduces spikes in CPU, RAM and disk IO load on the remaining vmstorage nodes during rolling restart. Smaller duration reduces the time needed to close all the vminsert connections, thus reducing the time for graceful shutdown. Configured value must always be lower than the graceful shutdown period configured by the orchestration platform (terminationGracePeriodSeconds for Kubernetes). See https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#improving-re-routing-performance-during-restart (default 10s)
  -storageDataPath string
    	Path to storage data (default "vmstorage-data")
  -tls array
    	Whether to enable TLS for incoming HTTP requests at the given -httpListenAddr (aka https). -tlsCertFile and -tlsKeyFile must be set if -tls is set. See also -mtls
    	Supports array of values separated by comma or specified via multiple flags.
    	Empty values are set to false.
  -tlsCertFile array
    	Path to file with TLS certificate for the corresponding -httpListenAddr if -tls is set. Prefer ECDSA certs instead of RSA certs as RSA certs are slower. The provided certificate file is automatically re-read every second, so it can be dynamically updated. See also -tlsAutocertHosts
    	Supports an array of values separated by comma or specified via multiple flags.
    	Each array item can contain comma inside single-quoted or double-quoted string, {}, [] and () braces.
  -tlsCipherSuites array
    	Optional list of TLS cipher suites for incoming requests over HTTPS if -tls is set. See the list of supported cipher suites at https://pkg.go.dev/crypto/tls#pkg-constants
    	Supports an array of values separated by comma or specified via multiple flags.
    	Each array item can contain comma inside single-quoted or double-quoted string, {}, [] and () braces.
  -tlsKeyFile array
    	Path to file with TLS key for the corresponding -httpListenAddr if -tls is set. The provided key file is automatically re-read every second, so it can be dynamically updated. See also -tlsAutocertHosts
    	Supports an array of values separated by comma or specified via multiple flags.
    	Each array item can contain comma inside single-quoted or double-quoted string, {}, [] and () braces.
  -tlsMinVersion array
    	Optional minimum TLS version to use for the corresponding -httpListenAddr if -tls is set. Supported values: TLS10, TLS11, TLS12, TLS13
    	Supports an array of values separated by comma or specified via multiple flags.
    	Each array item can contain comma inside single-quoted or double-quoted string, {}, [] and () braces.
  -version
    	Show VictoriaMetrics version
  -vminsertAddr string
    	TCP address to accept connections from vminsert services (default ":8400")
  -vmselectAddr string
    	TCP address to accept connections from vmselect services (default ":8401")
