FIGURE 2 Above event trigger with buffer zone
Below event trigger
The Below event trigger generates an event when a data value becomes less than the low threshold
boundary.
When a buffer is defined, the event will be triggered only when the value goes below the lower
threshold. A second event will not be generated until the value crosses the buffer region set above the
lower threshold.
Audit and RASLog messages
Fabric Watch generates an Audit message along with a RASLog message when the current threshold
exceeds the high threshold limit configured for the following thresholds:
• SCSI reservation
• Class 3 discards (C3TXT0)
• Switch memory usage
• Switch flash usage
• Switch CPU usage
Time bases
Time bases specify the time interval between two samples to be compared. You can set the time base
to day (samples are compared once a day), hour (samples are compared once an hour), minute
(samples are compared every minute). This configurable field affects the comparison of sensor-based
data with user-defined threshold values.
Time base set to none
If you set a time base to none, Fabric Watch compares a data value against a threshold boundary level.
When the absolute value of the measuring counter exceeds the threshold boundary, an event is
triggered.
