This watch uses an alarm type of AutomaticReset, which means that it may be triggered repeatedly, provided that the last time it was triggered was longer than the
interval set as the alarm reset period in this case 10000 milliseconds.
The severity level provided, Warning, has no effect on the triggering of the watch, but will be passed on through the notifications.
9.4 Configuring Log Watches
Use Log watches to monitor the occurrence of specific messages andor strings in the server log. Watches of this type are triggered as a result of a log message containing
the specified data being issued.
An example configuration for a log watch is shown in Example 9–2
.

9.5 Configuring Instrumentation Watches
You use Instrumentation watches to monitor the events from the WLDF Instrumentation component. Watches of this type are triggered as a result of the event
being posted.
Example 9–3 shows an example configuration for an Instrumentation watch.
