Configuring Performance Alerts

May 9, 2024

Contributed by:

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 storage repository (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). You can have performance alerts emailed to you. You can also enable an SNMP trap to be sent to your SNMP manager, also known as a network management system (NMS). For more information, see XenCenter Alerts.

You can configure performance alerts for servers, VMs, or SRs. To configure performance alerts:

Select the server, VM, or SR in the Resources pane. Select the General tab and then click Properties.

Select the Alerts tab. The following table summarizes which alerts are available for servers, VMs, or SRs:

Alert name	Server	VM	SR	Description
Generate CPU usage alerts	X	X		Set the CPU usage and time threshold that trigger the alert.
Generate control domain CPU usage alerts	X			Set the control domain CPU usage and time threshold that trigger the alert.
Generate memory usage alerts	X			Set the memory usage and time threshold that trigger the alert.
Generate control domain memory usage alerts	X			Set the control domain memory usage and time threshold that trigger the alert.
Generate control domain free memory alerts	X			Set the control domain free memory and time threshold that trigger the alert.
Generate disk usage alerts		X		Set the disk usage and time threshold trigger the alert.
Generate storage throughput alerts			X	Set the storage throughput and time threshold that trigger the alert. Note: Physical Block Devices (PBD) represent the interface between a specific XenServer server 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 server connected to the PBD. Unlike other XenServer server alerts, this alert must be configured on the SR.
Generate network usage alerts	X	X		Set the network usage and time threshold that trigger the alert.

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.

Click OK to save your changes.
