About Recovery Actions

The PATROL KM for Event Management recovery actions are distinct recovery actions that are unrelated to the recovery actions you can define in a KM using the PATROL Console for Windows or the PATROL Console for Unix. For the sake of discussion, the recovery actions that you define in the KM using the PATROL console are referred to as PATROL native recovery actions. The following sections explain the differences between PATROL native recovery actions and PATROL KM for Event Management recovery actions.

PATROL Native Recovery Actions

When you define PATROL native recovery actions in the PATROL console, you associate the recovery actions with alarm and border ranges. These recovery actions run when the PATROL parameter value enters the specified range. The parameter may be in an OK, WARN, or ALARM state when the recovery action runs, depending on how you configure the parameter.

PATROL KM for Event Management Recovery Actions

Unlike PATROL native recovery actions, the PATROL KM for Event Management Recovery actions run only when a parameter changes status. For example, when a parameter goes from an OK state to a WARN or ALARM state, or even when a parameter goes from an ALARM to an OK state.

If you don't want the parameter to alarm until recovery actions have been attempted, you must use PATROL native recovery actions, rather than PATROL KM for Event Management recovery actions. However, you can use both types. For example, you could define PATROL native recovery actions and specify that the parameter enters a WARN or ALARM state only after all recovery actions fail. Then you could create a PATROL KM for Event Management recovery action that runs only if the PATROL native recovery actions fail.
