### List of command-line flags for vminsert
Below is the output for `/path/to/vminsert -help`:
```
-clusternativeListenAddr string
TCP address to listen for data from other vminsert nodes in multi-level cluster setup. See https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#multi-level-cluster-setup . Usually :8400 must be set. Doesn't work if empty
-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)
-disableRerouting
Whether to disable re-routing when some of vmstorage nodes accept incoming data at slower speed compared to other storage nodes. By default the re-routing is enabled. 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
-enableTCP6
Whether to enable IPv6 for listening and dialing. By default only IPv4 TCP and UDP is used
-envflag.enable
Whether to enable reading flags from environment variables additionally to command line. Command line flag values have priority over values from environment vars. Flags are read only from command line if this flag isn't set
-envflag.prefix string
Prefix for environment variables if -envflag.enable is set
-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()
-graphiteListenAddr string
TCP and UDP address to listen for Graphite plaintext data. Usually :2003 must be set. Doesn't work if empty

-influxSkipSingleField
Uses '{measurement}' instead of '{measurement}{separator}{field_name}' for metic name if Influx line contains only a single field
-influxTrimTimestamp duration
Trim timestamps for Influx line protocol 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)

-maxInsertRequestSize size
The maximum size in bytes of a single Prometheus remote_write API request
Supports the following optional suffixes for size values: KB, MB, GB, KiB, MiB, GiB (default 33554432)

-replicationFactor int
Replication factor for the ingested data, i.e. how many copies to make among distinct -storageNode instances. Note that vmselect must run with -dedup.minScrapeInterval=1ms for data de-duplication when replicationFactor is greater than 1. Higher values for -dedup.minScrapeInterval at vmselect is OK (default 1)
-rpc.disableCompression
Whether to disable compression of RPC traffic. This reduces CPU usage at the cost of higher network bandwidth usage
-sortLabels
Whether to sort labels for incoming samples before writing them to storage. This may be needed for reducing memory usage at storage when the order of labels in incoming samples is random. 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

The maximum time the request waits for execution when -search.maxConcurrentRequests limit is reached; see also -search.maxQueryDuration (default 10s)
-search.maxStalenessInterval duration
The maximum interval for staleness calculations. By default it is automatically calculated from the median interval between samples. This flag could be useful for tuning Prometheus data model closer to Influx-style data model. See https://prometheus.io/docs/prometheus/latest/querying/basics/#staleness for details. See also '-search.maxLookback' flag, which has the same meaning due to historical reasons
-search.maxStatusRequestDuration duration
The maximum duration for /api/v1/status/* requests (default 5m0s)
-search.maxStepForPointsAdjustment duration
The maximum step when /api/v1/query_range handler adjusts points with timestamps closer than -search.latencyOffset to the current time. The adjustment is needed because such points may contain incomplete data (default 1m0s)
-search.minStalenessInterval duration
The minimum interval for staleness calculations. This flag could be useful for removing gaps on graphs generated from time series with irregular intervals between samples. See also '-search.maxStalenessInterval'
-search.queryStats.lastQueriesCount int
Query stats for /api/v1/status/top_queries is tracked on this number of last queries. Zero value disables query stats tracking (default 20000)
-search.queryStats.minQueryDuration duration
The minimum duration for queries to track in query stats at /api/v1/status/top_queries. Queries with lower duration are ignored in query stats
-search.resetCacheAuthKey string
Optional authKey for resetting rollup cache via /internal/resetRollupResultCache call
-search.treatDotsAsIsInRegexps
Whether to treat dots as is in regexp label filters used in queries. For example, foo{bar=~"a.b.c"} will be automatically converted to foo{bar=~"a\\.b\\.c"}, i.e. all the dots in regexp filters will be automatically escaped in order to match only dot char instead of matching any char. Dots in ".+", ".*" and ".{n}" regexps aren't escaped. This option is DEPRECATED in favor of {__graphite__="a.*.c"} syntax for selecting metrics matching the given Graphite metrics filter
-selectNode array
Addresses of vmselect nodes; usage: -selectNode=vmselect-host1:8481 -selectNode=vmselect-host2:8481
