URL Provided in Alert based on DataPoint

Assuming you leverage and consume custom alert messaging, you can define the KB article at the datasource template level. Taking your CPU utilization example, go to your CPU datasource LogicModule, and add the URL to the custom alert messaging for the desired datapoint triggering alerts. 

If the KB is different for different subset of resources, then the alert messaging should be updated to reference a custom property that would be assigned to or inherited by the resource. Example ##CPU_KB_URL##, then you would assign/inherit the cpu_kb_url property to your different subsets of resources. 

This does mean you will have to maintain these properties in LM.
