Data Sources

Updated: November 1, 2013

Applies To: System Center 2012 - Operations Manager, System Center 2012 R2 Operations Manager, System Center 2012 SP1 - Operations Manager

Monitors and rules in Operations Manager each start with a data source which defines where it will get the data to evaluate or collect. The first decision to make when you are defining a rule or monitor is the data source that it will use. The most straightforward method to answer this question is to determine where the information is that you want to collect or that indicates the condition you want to detect.

For example, an application may create an event in the Windows Event Log when a particular error occurs. You could create a rule that watches for this particular event and generates an alert when it detects one. If detection of the event is not possible through an event, a log, or a performance counter, then you may need to run a script on a periodic basis to retrieve the required information.

The same set of data sources is available for both monitors and rules as shown in the table below.
