When to use an event management policy rather than a rule

Use a policy if there is a fairly simple, routine action that you would like to apply to many events. If some complex event manipulation is required that is specific to a small subset of events, a rule written in MRL might be more appropriate.

In some cases, a rule can provide better performance than its event management policy equivalent. If an event management policy gives problematic performance, substituting an equivalent rule might rectify the performance issue.
