favor of alloy

vmagent can receive data via the same protocols as VictoriaMetrics Single or Cluster versions,
as well as scrape Prometheus endpoints. In other words,
it supports both [Push](https://docs.victoriametrics.com/keyconcepts/#push-model) and [Pull](https://docs.victoriametrics.com/keyconcepts/#pull-model) models.
This section of the documentation only covers forwarding data from vmagent to another destination.
For extra information about vmagent as well as quickstart guide please refer to the [vmagent documentation](https://docs.victoriametrics.com/vmagent/).
To configure vmagent to push metrics to VictoriaMetrics via Prometheus remote write protocol,
configure the `-remoteWrite.url` cmd-line flag:
```sh
/path/to/vmagent -remoteWrite.url=https://<victoriametrics_url>/api/v1/write
```
For pushing data to VictoriaMetrics cluster the `-remoteWrite.url` should point to vminsert and include
the [tenantID](https://docs.victoriametrics.com/cluster-victoriametrics/#url-format):
```sh
/path/to/vmagent -remoteWrite.url=https://<vminsert-addr>/insert/<tenant_id>/prometheus/api/v1/write
```
> Note: read more about [multitenancy](https://docs.victoriametrics.com/cluster-victoriametrics/#multitenancy)
> or [multitenancy via labels](https://docs.victoriametrics.com/cluster-victoriametrics/#multitenancy-via-labels).
Please note, `-remoteWrite.url` cmd-line flag can be specified multiple times with different values. In this case,
vmagent will [replicate](https://docs.victoriametrics.com/vmagent/#replication-and-high-availability) data to each
specified destination. In addition, it is possible to configure [metrics sharding](https://docs.victoriametrics.com/vmagent/#sharding-among-remote-storages)
across `-remoteWrite.url` destinations.
## Remote write with basic authentication
This requires setting the `-remoteWrite.basicAuth.username` and `-remoteWrite.basicAuth.password` command line flags:
```sh
/path/to/vmagent -remoteWrite.url=https://<victoriametrics_url>/api/v1/write \
-remoteWrite.basicAuth.username=<username> \
-remoteWrite.basicAuth.password=<password>
```
## Remote write with bearer Authentication
```sh
/path/to/vmagent -remoteWrite.url=https://<victoriametrics_url>/api/v1/write \
-remoteWrite.bearerToken=<token>
```
The token can be placed in a file and accessed via the `-remoteWrite.bearerTokenFile` command line argument.
The file needs to be readable by the user vmagent is running as. The token file should only contain the token as seen below:
```
<token>
```
The command to run vmagent with a token file will be the following:
```sh
/path/to/vmagent -remoteWrite.url=https://<victoriametrics_url>/api/v1/write \
-remoteWrite.bearerTokenFile=/path/to/tokenfile
```
## Ignore TLS/SSL errors
If you are using self-signed certificates you can either ignore certificates issues using
the `-remoteWrite.tlsInsecureSkipVerify`, which is a security risk, or use `-remoteWrite.tlsCAFile` to point
to a file containing the self-signed CA certificate:
```sh
/path/to/vmagent -remoteWrite.url=https://<victoriametrics_url>/api/v1/write \
-remoteWrite.tlsInsecureSkipVerify
```
