XenCenter Alerts

You can view different types of system alerts in XenCenter by clicking Notifications and then Alerts.

The Alerts view displays various types of alerts, for example:

  • 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.
  • License expiry alerts. Alerts will be generated when XenServer licenses on your managed servers are approaching their expiry dates or have expired.

Working with alerts

XenCenter is equipped with powerful filtering capabilities. It enables you to filter alerts displayed on the Alerts tab so you can view alerts only from specific pools or servers, or only those generated during a specific time period. For some alerts, it may be possible to quickly address the issue that caused the alert to be generated. The following table lists various options available in the Alerts view.

Filter by Severity

Filters alerts by their severity

By default, alerts of all severity levels will be displayed on the Alerts tab. To view alerts of a particular severity, click Filter by Severity and then cancel the selection on other severity levels from the list. Click Show All to view all the alerts.

Filter by Location

Filters alerts by the source from which they originate

By default, alerts from all hosts connected to XenCenter will be displayed. To stop displaying alerts from a specific host, click the drop-down list and cancel the selection on the host. Clicking again on the host toggles your selection.

Filter by Date

Filters alerts based on the time of occurrence

By default, all alerts for the current XenCenter session will be displayed. Click the drop-down list and select a date range from the list. Alternatively, click Custom to define your own date range by specifying the start and end date/time. Click Show All to view all the alerts.

Refresh

If new alerts are generated when the Alerts tab is open, they may not appear in the list. Click Refresh to view an updated the list.

Export All

Exports alerts as a comma delimited (.csv) file for viewing and analysis in external applications.

Receiving alert notifications by email

You can configure XenCenter to send email notifications when 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 XenServer xe command line interface (CLI). For more information, see Command line interface.

To turn on email notification

  1. Select a pool or standalone server in the Infrastructure view.
  2. click on the General tab and then Properties.
  3. Click on the Email Options tab in the Properties dialog box.
  4. Select the Send email alert notifications check box and then type 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 Monitor and manage.

  5. Click OK to save your changes and close the dialog box.
