System Center Operations Manager LogoToday I encounterd what seems to be a bug in the System Center 2012 Visual Studio Authoring Extensions. I wanted to define a Performance Collection Rule that reads out the percentage of free memory from an SNMP device.

Since the device returns only the percentage of used memory I needed to use the ComputedPerfProvider provider to substract the used memory percentage from 100.

I could of course report used memory instead of free memory but I wanted the resulst to appear in the default SCOM Performance View, which only lists Free Memory:

System Center Operations Manager | Default Performance View

System Center Operations Manager LogoI am currently working on a Management Pack for SCOM and I have studies a few examples on adding processor and memory counters.

These examples all reference a Management Pack named "System.NetworkManagement.Monitoring.mp" but this Management Pack is not bundled with the System Center 2012 Visual Studio Authoring Extensions.

I am currently working on a Management Pack for System Center Operations Manager (aka SCOM). I am using the System Center 2012 Visual Studio Authoring Extensions and during build of my project I suddenly got the following error: “MSB4018: The “MergeFragments” task failed unexpectedly“:

Visual Studio | System Center 2012 Visual Studio Authoring Extensions | C:\Program Files (x86)\MSBuild\Microsoft\VSAC\Microsoft.SystemCenter.OperationsManager.targets(234,5) | error MSB4018: The "MergeFragments" task failed unexpectedly.

I searched on this error message but wasn’t able to find anything helpful. In order to get more detailed output from MSBuild I changed the MSBuild project build output verbosity. To do this go to the Tools menu in Visual Studio and select Options. Navigate to the “Build and Run” node under “Projects and Solutions” and set both options to “Diagnostic”:

Visual Studio | Tools | Options | Projects and Solutions | Build and Run | MSBuild project build output verbosity | Diagnostic
