For quite a while now, Citrix is offering EdgeSight for performance analysis and historical reporting. It started off for endpoints and XenApp (still called Presentation Server at that time) and now includes virtual desktops as well. EdgeSight is offering a huge number of reports seemingly covering all possible aspects of performance analysis.
But in my eyes, the agents are collecting a lot more pieces of information than the reports are able to display. This article is the first in a series describing the EdgeSight database schema, what is necessary for a valid query and how it is built into a report.
