These days, server monitoring is no longer a luxury, it is an absolute necessity. With XenApp, Citrix provides a few tools. Some built in and others for an additional licensing cost. Below is a table sent to me by David Paoleschi comparing the various options between them. The new Resource Manager included in XenApp 5.0 is now a pretty full featured reporting system in its own right. Edgesight still gives administrators the detailed information necessary for post analysis and post mortems related to Application crashes and hangs.
