Management Pack on Remko's Blog

Set alert parameters with Visual Studio Authoring Extensions

In a SCOM Management Pack Custom Properties can be used for Alert Description and Notification as described in this blog by Kevin Holman.

In my case I wanted to add the Display Name and the Performance Counter Value in a Performance Threshold Monitor. In XML it would look this this:

xml Download

 <alertsettings alertmessage="Memory.Usage.AlertMessage">
 <alertonstate>Error</alertonstate>
 <autoresolve>true</autoresolve>
 <alertpriority>Normal</alertpriority>
 <alertseverity>MatchMonitorHealth</alertseverity>
 <alertparameters>
 <alertparameter1>$Target/Host/Property[Type="System!System.Entity"]/DisplayName$</alertparameter1>
 <alertparameter2>$Data/Context/Value$</alertparameter2>
 </alertparameters>
 </alertsettings>

But how to add these parameters when using the System Center 2012 Visual Studio Authoring Extensions?

non-existent schema type 'Snmp!System.SnmpVarBindsSchema' error in SCOM

Today 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:

Where to find System.NetworkManagement.Monitoring.mp?

I 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.
