XenCenter System Alerts

May 29, 2013

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, memory usage, network, storage throughput, or VM disk activity exceeds a specified threshold on a managed server, virtual machine, or storage repository. For information on configuring performance alerts, see Configuring performance alerts.
  • 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.

To filter the alerts displayed on the System Alerts window

You can apply filters to the alerts listed in the System Alerts window, for example, to view alerts only from specific pools or servers, or only generated during a specific time period.

  • To view alerts from specific servers: By default, alerts from all pools and servers which are connected to XenCenter are displayed on the System Alerts window. Therefore, all pool and server icons within the Filter Servers drop-down list are selected by default. To view alerts from a specific server, click Filter Servers and then deselect the pools and servers from which you do not want to see the system alerts. For example, consider a pool with two servers A and B. To view system alerts from server A, select Filter Servers and then click on server B. Clicking again on server B toggles your selection.
  • To filter the alerts by time or date: click Filter Dates and select a date range from the list, or click Custom and define your own date range by specifying the start and end date/time.
  • To filter the alerts by severities: By default, alerts of all severity levels will be displayed on the System Alerts window. To view alerts of a particular severity, click Filter Severities and then deselect other severity levels from the list.

To refresh the list of alerts

If new alerts are generated while the System Alerts window is open, you can click Refresh to update the list.

To export alerts

Alerts can be exported as a comma delimited (.csv) file for viewing and analysis in external applications.

To export system alerts from XenCenter, in the System Alerts window, click Export All and then specify the filename and location.

To dismiss system alerts

To dismiss or remove a single alert, select it and then click Dismiss.

To dismiss or remove all the current alerts, click Dismiss All.

To receive alert notifications by email

You can configure XenCenter to send email notifications when system alerts are generated for any of the servers and virtual machines in a pool, or for a standalone server and its virtual machines.

When you turn on the email notification feature, you will be sent an email notification when alerts with a priority of 3 or higher are generated. (You can assign a priority for different types of alerts through the XenServer xe command line interface (CLI); see the XenServer Administrator's Guide for details.)

To turn on email notification

  1. Select a pool or standalone server in the Resources pane, click on the General tab and then click Properties.
  2. Click on the Email Options tab in the Properties dialog box.
  3. Select the Send email alert notifications check box and then enter the delivery address details.
    Note: You should enter the details of an SMTP server which does not require authentication. Emails sent through SMTP servers which require authentication will not be delivered. For instructions on using authenticated SMTP servers to receive email notifications, see the XenServer Administrator's Guide.
  4. Click OK to save your changes and close the dialog box.
