Configuring Performance Alerts

Oct 09, 2015

You can configure XenCenter to generate alerts when CPU, network I/O or disk I/O usage go over a specified threshold on a managed server or virtual machine. By default, the alert repeat interval is 60 minutes, but you can configure this as well.

Performance alerts will appear in the System Alerts window (accessed by clicking on System Alerts at the top right corner of the XenCenter window). In addition, you can have performance alerts emailed to you along with other serious system alerts: see XenCenter system alerts.

To configure performance alerts:

  1. Select the server or virtual machine in the Resources pane, click on the General tab and then click Properties.
  2. Click on the Alerts tab and then:
    • To request CPU performance alerts for a server or virtual machine, select the Generate CPU usage alerts check box, then set the CPU usage and time threshold that will trigger the alert.
    • To request network performance alerts for a server or virtual machine, select the Generate network usage alerts check box, then set the network I/O usage and time threshold that will trigger the alert.
    • To request disk usage performance alerts for a virtual machine, select the Generate disk usage alerts check box, then set the disk I/O usage and time threshold that will trigger the alert.
    • To change the alert repeat interval, enter the number of minutes in the Alert repeat interval box. Once an alert threshold has been reached and an alert generated, another alert will not be generated until after the alert repeat interval has elapsed.
  3. Click OK to save your changes and close the dialog box.
