Here’s some notes I made on SCOM when I was talking about it to some colleagues. I am sure there is plenty more I could have said but this might serve as a good starting point for someone trying to understand the concepts.
Classes have the same properties of the base class plus their own. The values of the properties can of course be different.
Workflows targeted at a parent class also target the child (but not the other way round).
If a workflow is targeted at a class it will run on every agent that has an object of that class on it.
Hosting Relationship – i.e Windows Computer hosts Logical Disk (1 to Many) – most relevant.
The hosting class is knows as the parent class.
The hosted class is known as the child class.
Containment Relationship – i.e when an object is a member of a group (Many to Many)
Reference Relationship – i.e. if a databases references another database
Unit – Basic monitor
Rollup – Each target has Availability, Configuration, Performance and Security
Dependency – Used to rollup health across Hosting or Containment relationship
Rules can do various things including collect data, create an alert etc
Agents should be distributed amongst management servers.
Overrides used to change the properties of a rule/monitor for a particular class, group or object. i.e disable a monitor, change the alerting threshold.
Run As Configuration – Some workflows have their own Profiles associated with them. The Profile can be populated with specific accounts otherwise the default action account is used.
Performance Counters – Create performance based collection rules to collect additional counters.
Notifications – Done through combination of channel and subscriber.
Can target only specific monitors/alerts for specific groups/people.
Data Warehouse – No datawarehouse server as such but it is a separate database.
Dashboards get data from DW performance views get data from main database.
Retention settings can be changed with a tool called dwdatarp.exe or in SQL directly.
Additional components to look at:
Service Level Tracking
Global Service Monitor (GSM)
Web Application Transaction Monitoring
Monitoring Network Devices
