# netdata-server Configures netdata to monitor the host and send alerts. ## Alerts Make sure to set `netdata_from_email` and `netdata_to_email` and to configure the `msmtp_relay` role. You can override alarm settings in `files/health_override.conf` ## Incoming replication If you set `netdata_master` to `true` it will also act as a central target for other collectors. Set `netdata_apikey` to a valid UUID (you can use `uuidgen` for that) and make sure to use the same value on all collectors.
