SCOM: Understanding Optimized Collection

Share on Social Media

This posting is a follow on in my SCOM basics series.

Lets start with what is Optimized Collection?

Optimization for a collection rule only collects a value if it differs from the previous sample by a specified tolerance. This is used to reduce network traffic and the amount of data stored in the Operations Manager database.

When viewing performance data you need to bear in mind that if the collection rule has optimization enabled then you may see gaps in your graphs if the value has not changed significantly for some time. The below image is an example of how this might look:

Note: Optimization should be used for performance counters that are expected to only change gradually. For counters that are expected to vary significantly from one value to the next, optimized collection should be disabled.
