Generates a defined alarm event only
if IBM® Systems Director does not receive
a specified event within a specified time range. This
event action is useful for monitoring for a loss of function, much
like a heartbeat monitor.
- Requirements
- None
- Result
- An event triggers an event automation plan that contains
this event action. The action is invoked and it starts a timer. If
another event of the same type is received before the timer expires,
nothing further happens. However, if the timer does expire, an
alarm event is generated by this action.
- Example
- You can use this action to make sure that something happens repeatedly
or within a given amount of time. After the timer expires and the
alarm event is sent, the monitoring process of this event action stops.
For example, you can monitor Common Agent to go offline
on a system. If Common Agent does
not return online within a given amount of time, you can power off
that system.
Note: You also can stop the monitoring process
by setting the timer value to 0. This
capability is
useful if you want to stop the process without deleting the event
action or the
event automation plan.
Tip: You can use event-data-substitution variables
in the following fields: Timed alarm ID, Program file name, and Working directory.
