See https://docs.victoriametrics.com/victoriametrics/enterprise/
  -clusternative.vminsertConnsShutdownDuration duration
     The time needed for gradual closing of upstream vminsert connections during graceful shutdown. Bigger duration reduces spikes in CPU, RAM and disk IO load on the remaining lower-level clusters during rolling restart. Smaller duration reduces the time needed to close all the upstream vminsert connections, thus reducing the time for graceful shutdown. See https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#improving-re-routing-performance-during-restart (default 25s)
  -clusternativeListenAddr string
     TCP address to listen for data from other vminsert nodes in multi-level cluster setup. See https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#multi-level-cluster-setup . Usually :8400 should be set to match default vmstorage port for vminsert. Disabled work if empty

  -disableRerouting
     Whether to disable re-routing when some of vmstorage nodes accept incoming data at slower speed compared to other storage nodes. Disabled re-routing limits the ingestion rate by the slowest vmstorage node. On the other side, disabled re-routing minimizes the number of active time series in the cluster during rolling restarts and during spikes in series churn rate. See also -disableReroutingOnUnavailable and -dropSamplesOnOverload (default true)
  -disableReroutingOnUnavailable
     Whether to disable re-routing when some of vmstorage nodes are unavailable. Disabled re-routing stops ingestion when some storage nodes are unavailable.

  -dropSamplesOnOverload
     Whether to drop incoming samples if the destination vmstorage node is overloaded and/or unavailable. This prioritizes cluster availability over consistency, e.g. the cluster continues accepting all the ingested samples, but some of them may be dropped if vmstorage nodes are temporarily unavailable and/or overloaded. The drop of samples happens before the replication, so it's not recommended to use this flag with -replicationFactor enabled.
  -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

For example, if m{k1="v1",k2="v2"} may be sent as m{k2="v2",k1="v1"}. Enabled sorting for labels can slow down ingestion performance a bit
  -storageNode array
     Comma-separated addresses of vmstorage nodes; usage: -storageNode=vmstorage-host1,...,vmstorage-hostN . Enterprise version of VictoriaMetrics supports automatic discovery of vmstorage addresses via DNS SRV records. For example, -storageNode=srv+vmstorage.addrs . See https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#automatic-vmstorage-discovery
     Supports an array of values separated by comma or specified via multiple flags.
     Value can contain comma inside single-quoted or double-quoted string, {}, [] and () braces.
  -storageNode.discoveryInterval duration
     Interval for refreshing -storageNode list behind DNS SRV records. The minimum supported interval is 1s. See https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#automatic-vmstorage-discovery . This flag is available only in VictoriaMetrics enterprise. See https://docs.victoriametrics.com/victoriametrics/enterprise/ (default 2s)
  -storageNode.filter string
     An optional regexp filter for discovered -storageNode addresses according to https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#automatic-vmstorage-discovery. Discovered addresses matching the filter are retained, while other addresses are ignored. This flag is available only in VictoriaMetrics enterprise. See https://docs.victoriametrics.com/victoriametrics/enterprise/
  -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.
  -tlsAutocertCacheDir string
     Directory to store TLS certificates issued via Let's Encrypt. Certificates are lost on restarts if this flag isn't set. This flag is available only in Enterprise binaries. See https://docs.victoriametrics.com/victoriametrics/enterprise/
  -tlsAutocertEmail string
     Contact email for the issued Let's Encrypt TLS certificates. See also -tlsAutocertHosts and -tlsAutocertCacheDir . This flag is available only in Enterprise binaries. See https://docs.victoriametrics.com/victoriametrics/enterprise/
  -tlsAutocertHosts array
     Optional hostnames for automatic issuing of Let's Encrypt TLS certificates. These hostnames must be reachable at -httpListenAddr . The -httpListenAddr must listen tcp port 443 . The -tlsAutocertHosts overrides -tlsCertFile and -tlsKeyFile . See also -tlsAutocertEmail and -tlsAutocertCacheDir . This flag is available only in Enterprise binaries. See https://docs.victoriametrics.com/victoriametrics/enterprise/
     Supports an array of values separated by comma or specified via multiple flags.
     Value can contain comma inside single-quoted or double-quoted string, {}, [] and () braces.
  -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.
     Value 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.
     Value 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.
     Value 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.
     Value can contain comma inside single-quoted or double-quoted string, {}, [] and () braces.
  -usePromCompatibleNaming
     Whether to replace characters unsupported by Prometheus with underscores in the ingested metric names and label names. For example, foo.bar{a.b='c'} is transformed into foo_bar{a_b='c'} during data ingestion if this flag is set. See https://prometheus.io/docs/concepts/data_model/#metric-names-and-labels

  -vmstorageDialTimeout duration
     Timeout for establishing RPC connections from vminsert to vmstorage. See also -vmstorageUserTimeout (default 3s)
  -vmstorageUserTimeout duration
     Network timeout for RPC connections from vminsert to vmstorage (Linux only). Lower values speed up re-rerouting recovery when some of vmstorage nodes become unavailable because of networking issues. Read more about TCP_USER_TIMEOUT at https://blog.cloudflare.com/when-tcp-sockets-refuse-to-die/ . See also -vmstorageDialTimeout (default 3s)
