XMS can also log monitor values to a file. You can enable this by adding a tag inside your XMSMonitoringService service tag.

<service class="xms.monitoring.XMSMonitoringService">
	<monitorfile path="log/monitor.log" interval="1000" append="false" />
</service>

The above configuration writes the monitor values to the file: log/monitor.log every 1 second.
