+# 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.
