Have you faced a problem where the Citrix SCOM Management Pack for XenApp & XenDesktop (MPXAXD) is not discovering your applications? This issue may occur when your number of applications is greater than the number of applications currently supported by the SCOM Management Pack for XenApp & XenDesktop. That limit is around 1,500 applications.

As of version 3.11 of the SCOM Management Pack, we have made performance improvements related to data retrieval from the XenApp and XenDesktop environments. However, with release 3.12 and above, this limit is no longer present when using connectors. This blog post still gives you a solution for version 3.11 and with it you can discover more than 1,500 applications using the following method. We have tested the discovery of up to 4,500 applications in our lab environment.apptopo

The existing management pack has five discoveries for applications. Each discovery can discover approximately 300 applications. We have created a custom management pack that includes an additional 10 discoveries to be able to discover a total of 4,500 applications.

You can download the custom management pack example here. Import the downloaded custom management pack to your SCOM console. With this management pack, there will be a total of 15 discoveries.

This is everything you need to do to increase the number of applications discovered on your Citrix SCOM Management Pack for XenApp and XenDesktop.
