We utilize Citrix quite a bit, so one of our core monitoring interests in rolling out SCOM was to monitor our Citrix farm.  I was pleased to find out that Citrix has a management pack.  Too bad it is complete junk.

It never found our zone data collector and wanted to tell us every time printer defaults were used.

In the end I simply uninstalled it and am now using this as an opportunity to teach myself about monitor authoring.
