The following table displays the system events/conditions that will a trigger an alert to be displayed in XenCenter System Alerts window.





 

XenCenter System Alerts

You can view a range of different types of alert in the System Alerts window, including:

• Performance alerts. Performance alerts may be generated when CPU, network I/O or disk I/O usage exceed a specified threshold on a managed server or virtual machine.
• HA (High Availability) status alerts. Alerts may be generated for changes to a pool's high availability status, such as when a pool becomes over committed.
• Software update alerts. Alerts may be generated when updates or new versions of XenServer or XenCenter are available.
• License expiry alerts. Alerts will be generated when the XenServer licenses on your managed servers are approaching their expiry dates or have expired.

For some alerts, it may be possible to resolve the issue that caused the alert to be generated by clicking on one of the Alert Actions links below the list of alerts.
