# System monitoring

OneSpan Authentication Server can be configured to monitor certain system events as they are written to the audit file. Filters must be defined to specify which events to monitor (see [Filters](/sec/docs/oas-cfgut-csh-system-monitoring-3-28#filters)). One or more targets must be specified to which messages are sent when the monitored event occurs (see [Targets](/sec/docs/oas-cfgut-csh-system-monitoring-3-28#targets)).

Click Enable System Monitoring to enable system monitoring on your OneSpan Authentication Server instance. Then use the Monitoring > Filters tab and the Monitoring > Targets tab to define your SNMP filters and targets.

## Filters

You must have at least one target configured, before you can add a filter (see [Targets](/sec/docs/oas-cfgut-csh-system-monitoring-3-28#targets)).

In the Monitoring > Filters tab, click Add to create a new filter via the Filter Details dialog.

Click New to create a new filter condition. Adding filter conditions will further narrow the audit messages that are monitored.

Click OK to insert the new filter.

## Targets

A target defines where notifications will be sent to when a monitored event occurs. At least one target must be defined before you can add filters (see [Filters](/sec/docs/oas-cfgut-csh-system-monitoring-3-28#filters)). You can define as many targets as you like.
