Instance Parameters

Instance Parameters
Instances are the system performance elements that the Express5800/320Ma SAM
monitors; for example, CPU usage, free disk space, and so on. A description of the
instances and related settings follows.
The Enable alerts for selected instance setting enables warnings and alarms to be
generated when the monitored component highlighted in the Select Instance menu
exceeds its thresholds.
Figure 2-1 shows alerts enabled for the CPU Usage instance.

Figure 2-1. Enabling Alerts

If you enable alerts for an instance, you must select at least one threshold value.
Figure 2-2 shows the Scan Poll Rate, Email Alert ID, and Program Launch fields.

Figure 2-2. Scan Poll Rate, Email Alert ID, and Program to Launch

Scan Poll Rate (in seconds). The interval, in seconds, at which SAM will scan (poll)
an instance to detect a possible threshold violation. If this rate is 300, for example, SAM
scans the instance's value once every 300 seconds, until detecting a threshold
violation.
However, whether a threshold violation actually occurs also depends on whether Scan
retry is enabled or disabled.
