Editing a threshold policy
11
7. (Fabric OS only) Enter a percentage for the low boundary in the Low Boundary field.
When the counter value goes below the low boundary an event is raised.
8. (Fabric OS only) Enter a percentage for the buffer in the Buffer Size field.
Counters may fluctuate around the upper or lower boundary of a range threshold, and as a
result cause numerous events in a short period of time. To reduce the number of events,
configure a buffer (a range of values just below the upper boundary and just above the lower
boundary) in which a counter does not register an event if it returns to a “normal” value. An
event only registers if the counter returns to a “normal” value beyond the buffer.
9. Click the right arrow button to move the threshold to the Selected Thresholds table.
If an error is detected, a message displays informing you to enter a valid value. Click OK to
close this message. Fix any errors and repeat step 9.
10. Repeat steps 5 through 9 for each measure that you want to add to the policy.
11. Click OK on the New Threshold Policy dialog box.
The threshold policy displays in the Available Threshold Policies table with an added icon ( ).
To assign a threshold policy to a fabric or device, refer to “Assigning a threshold policy” on
page 313.
