Is your Operations Manager console slow when editing groups? If so here’s a tip to get you back in the fast lane

Is your System Center Operations Manager 2007 admin console slow when editing groups?  If so, you ought to take a close look at the membership rules, especially if you are using complex regular expression substring searches like below…



Searches like this will result in a very heavy SQL load that can effectively hang the console until the calculation is complete.  It is far better to rewrite the membership rule to combine the search into a single regular expression such as this one below (?i: at the beginning of the expression is a directive to do a case-insensitive search):



To give you some idea of the performance improvement, this very change allowed a query that took approximately 10 minutes to complete to finish in approximately 1 second.

It is worth noting that OpsMgr regularly performs group membership calculation and any improvement in this area is going to result in general performance improvements within OpsMgr.

Hope this helps,

    To find the groups that possible have a performance impact,  I created a script to retrieve the Discovery Configuration to see if a lot of membership rules and expressions are defined:…/scom-find-those-heavy-group-discoveries.html

    Hi 😉 I made a video about this some time ago

    What i did not know was the case sensitive character….

    I found this solution because every month the list of the servers was change.

    I would say I definitely have issues in this area.  is there a way to show the calculation queries of each group as a list or report?  Or perhaps a way to show what queries are taking the most time?


  4. @Jonathan – Interesting point about the speed of regexp vs. a bunch of WHERE and OR clauses… you did well pointing it out as it might not be obvious to most. I do find that GroupCalc makes systems very busy, also in terms of Config Churn as those Groups keep changing… something to be aware about.

    @cornasdf – this should be visible on the SQL side, not on the OpsMgr side… likely SQL profiler, or even SQL2005/2008 might have some canned reports in that area….
