About Performance Monitoring

The Performance tab in XenCenter provides real time monitoring of performance statistics across resource pools as well as graphical trending of virtual and physical machine performance.

  • You can view up to 12 months of performance data and zoom in to take a closer look at activity spikes. To learn more, see Viewing performance data.
  • By default, graphs showing CPU, memory, network I/O and disk I/O are displayed on the tab. However, you can add more performance data and change the appearance of the graphs. To learn more, see Configuring performance graphs
  • Performance alerts can be generated when CPU, memory usage, network, storage throughput, or VM disk activity go over a specified threshold on a managed server, virtual machine, or storage repository. For more information, see Configuring performance alerts.


Full performance data is only available for virtual machines with the XenServer paravirtualized drivers (XenServer Tools) installed.
