Citrix PVS Accelerator for XenServer

Citrix PVS Accelerator for XenServer

This template contains performance & statistics counters for monitoring PVS Accelerator metrics implemented in XenServer as a result of integration of PVS Accelerator & XenServer.

Some of the counters may require manual configuration, such as setting up installation-specific instances, correcting thresholds for the client’s environment, and so forth.

Prerequisites:

• 1. XenServer 7.5 or 7.6
• 2. PVS 7.13 or later
• 3. PVSAccelerator must be enabled on the given XenServer

Credentials: SSH Access to the Linux machine hosting XenServer 7.5 or 7.6.

Notes:

1. 1. Whatever metric you are putting on monitoring, that metric must be available in rrd2csv command output executed directly on XenServer.

If you don't find the required metric in above command output, then there must be 2 reasons. Either that metric is not enabled or that metric settings are not configured.

1. 2. To find the list of metrics which you can monitor, you need to run the below command directly on the XenServer.

xe host-data-source-list hostname=<XenServerHostname>

If you see the required metric in point above command output but not in rrd2csv command output, then it means you need to enable that metric. Here is how you can enable that metric:

xe host-data-source-record data-source=metric name host=hostname

Once the above command is successful, that metric should be seen in rrd2csv command output.

1. 3. If you don't see the required metric in point 2 commands output then that metric is not configured. You need to check with your XenServer/PVS administrator to configure the settings required for that metric.
2. 4. As Citrix Server itself is Linux based, this template will be running against the Linux agent.
