Note:

XenCenter 2023.x.x is currently in preview and is not supported for production use. Note that any future references to production support apply only when XenCenter 2023.x.x and XenServer 8 go from preview status to general availability.

You can use XenCenter 2023.x.x to manage your XenServer 8 and Citrix Hypervisor 8.2 CU1 non-production environments. However, to manage your Citrix Hypervisor 8.2 CU1 production environment, use XenCenter 8.2.7. For more information, see the XenCenter 8.2.7 documentation.

You can install XenCenter 8.2.7 and XenCenter 2023.x.x on the same system. Installing XenCenter 2023.x.x does not overwrite your XenCenter 8.2.7 installation.

Performance alerts can be generated when CPU, memory usage, network, storage throughput, or VM disk activity exceeds a specified threshold on a server, VM, or SR. By default, the alert repeat interval is set to 60 minutes, and it can be modified if necessary.

Performance alerts appear in the Alerts view (accessed by clicking the Notifications button on the left hand pane). In addition, you can have performance alerts emailed to you along with other alerts: see XenCenter Alerts.

To configure performance alerts:

  1. Select the server, VM, or storage repository in the Resources pane. Select the General tab and then click Properties.
  2. Select the Alerts tab and then:
    • To request CPU performance alerts for a server or virtual machine, select the Generate CPU usage alerts check box. Set the CPU usage and time threshold that trigger the alert.
    • To request network performance alerts for a server or virtual machine, select the Generate network usage alerts check box. Set the network usage and time threshold that trigger the alert.
    • To request memory performance alerts for a server, select the Generate memory usage alerts check box. Set the memory usage and time threshold that trigger the alert.
    • To request disk usage performance alerts for a virtual machine, select the Generate disk usage alerts check box. Set the disk usage and time threshold trigger the alert.

    • To request storage throughput alerts for a storage repository, select the Generate storage throughput alerts check box. Set the storage throughput and time threshold that trigger the alert.

      Note:

      This option generates alerts when the total read/write storage throughput activity on a Physical Block Device (PBD) exceeds the specified limit. PBD represents the interface between a specific XenServer host and an attached SR. When the total read/write SR throughput activity on a PBD exceeds the threshold you have specified, alerts are generated on the host connected to the PBD. Unlike other host alerts, this alert must be configured on the relevant SR.

    • To change the alert repeat interval, enter the number of minutes in the Alert repeat interval box. After an alert threshold is reached and an alert generated, another alert is not generated until after the alert repeat interval has elapsed.
  3. Click OK to save your changes.
