15. Basic Discovery Script ‘Setup the objects Set oAPi = CreateObject (“MOM.ScriptAPI”) Set oDiscoveryData = oAPI.CreateDiscoveryData(0,SourceId, ManagedEntityId) ‘Create Discovery Instance Set oInstance = oDiscoveryData.CreateClassInstance( “$MPElement[Name=‘ClassName’]$”) oInstance.AddProperty “$MPElement[Name=‘ClassName’]/Property1$, Value1 oDiscoveryData.AddInstance oInstance ‘Return discovery data oAPI.Return oDiscoveryData

18. Running A Rule During Business Hours

20. Data Source Probe Action Condition Detection Write Action Does not take input, generates output based on external sources. Does not change object state. One input and zero or one output streams. Changes object state. Always the last module in Rules and Recoveries. One or more input streams, one output. No external sources and no state changes. One input and one output; when triggered, generates output from external sources.

22. Creating a Custom Data Source

23. Creating a Custom Unit Monitor

25. Monitor: MyMP.Monitor.MyCustomMonitor1 Date Source: Simple.Scheduler Probe: MyCustomProbe Condition Detection: My Results Filter Monitor: MyMP.Monitor.MyCustomMonitor2 Date Source: MyCustomData Source Condition Detection: Schedule Filter Monitor: MyMP.Monitor.MyCustomAlertRule Date Source: MyCustomData Source Condition Detection: Consolidator Write Action: Generate Alert DataSource: MyCustomDataSource Date Source: Simple.Scheduler Probe: MyCustomProbe Condition Detection: My Results Filter MyCustomMonitor1 has been configured with a probe so it can use on-demand detection MyCustomMonitor2 is using a custom data source that makes use of our probe. It also has a schedule filter configured MyCustomAlertRule is collecting events using our custom data source, and only alerting if certain events show up in order MyCustomDatasource is collecting events on a timer from a text log, and ignoring informational events

26. Monitor: MyMP.Monitor.MyCustomMonitor1 Date Source: Simple.Scheduler Probe: MyCustomProbe Monitor: MyMP.Monitor.MyCustomMonitor2 Condition Detection: Schedule Filter Monitor: MyMP.Monitor.MyCustomAlertRule Condition Detection: Consolidator Write Action: Generate Alert Date Source: Simple.Scheduler Probe: MyCustomProbe Condition Detection: My Results Filter Date Source: Simple.Scheduler Probe: MyCustomProbe Condition Detection: My Results Filter Condition Detection: My Results Filter For each workflow, SCOM builds an execution chain. The first step is to resolve/expand all modules to their root definitions, and place them into the chain. So, all our instances of the custom data source are replaced with the modules that make up the data source. Each chain is analyzed, and each module’s input parameters submitted to a hash function. If module IDs and hash results are the same, that indicates duplicate modules that are candidates for cookdown.

27. Cooked Down Workflow Date Source: Simple.Scheduler Probe: MyCustomProbe Condition Detection: My Results Filter Monitor: MyMP.Monitor.MyCustomMonitor1 Monitor: MyMP.Monitor.MyCustomMonitor2 Monitor: MyMP.Monitor.MyCustomAlertRule Condition Detection: Schedule Filter Condition Detection: Consolidator Write Action: Generate Alert Since the first three modules were all configured identically, they are cooked down and run once, with the output replayed to each consuming workflow
