Alert Thresholds
(An instance can also theoretically be configured with both high and low thresholds,
each with warning and alarm conditions, totaling four settings, though there is currently
no instance that needs this.)

Threshold Units

Each instance includes a Units item (shown in
system automatically sets this parameter.
The Units parameter determines the unit of measure being scanned and interpreted as
high or low. Unit values are:
•
Percent, a value, from 1 to 100, of a component's capacity.
•
Megabytes, units of 1,048,576 bytes.
•
Count, for discrete quantity, like the number of context switches per second.
•
Message, for those instances whose only action is to receive messages, like
Application Fault Monitor.
For example, the CPU Usage instance's Units parameter is defined as Percent.
Therefore, a High Threshold Alarm value of 90 means that SAM will produce an alarm
when the CPU is operating at 90% of capacity. On the other hand, the Memory
Available instance's Units parameter is set to Megabytes. Therefore, a Low Threshold
Alarm value of 4 means that the system will produce a Low Threshold Alarm alert when
only 4 MB of memory are available.
