If multiple labels needs to be added, set flag for each label, for example, `--vm-extra-label label1=value1 --vm-extra-label label2=value2`.
If timeseries already have label, that must be added with `--vm-extra-label` flag, flag has priority and will override label value from timeseries.
### Rate limiting
Limiting the rate of data transfer could help to reduce pressure on disk or on destination database.
The rate limit may be set in bytes-per-second via `--vm-rate-limit` flag.
Please note, you can also use [vmagent](https://docs.victoriametrics.com/vmagent.html)
as a proxy between `vmctl` and destination with `-remoteWrite.rateLimit` flag enabled.
## How to build
It is recommended using [binary releases](https://github.com/VictoriaMetrics/VictoriaMetrics/releases) - `vmctl` is located in `vmutils-*` archives there.
