# MaxScale 24.02 Configuring the Galera Monitor

This document describes how to configure a Galera cluster monitor.

### Configuring the Monitor

Define the monitor that monitors the servers.

```
[Galera-Monitor]
type=monitor
module=galeramon
servers=dbserv1, dbserv2, dbserv3
user=monitor_user
password=my_password
monitor_interval=2000ms
```

The mandatory parameters are the object type, the monitor module to use, the\
list of servers to monitor and the username and password to use when connecting\
to the servers. The `monitor_interval` parameter controls for how long\
the monitor waits between each monitoring loop.

This monitor module will assign one node within the Galera Cluster as the\
current primary and other nodes as replica. Only those nodes that are active\
members of the cluster are considered when making the choice of primary node. The\
primary node will be the node with the lowest value of `wsrep_local_index`.

### Monitor User

The monitor user does not require any special grants to monitor a Galera\
cluster. To create a user for the monitor, execute the following SQL.

```
CREATE USER 'monitor_user'@'%' IDENTIFIED BY 'my_password';
```
