• Configure threshold intervals you Add at the bottom of this screen according to the
following parameters.
• Attribute Nam
e — Appears when you click Add rather than Editing a selected threshold.
Use the pick list that appears in this screen to select the attribute for which you are
specifying threshold information. When you Edit, the name of the attribute appears as a
title within the editor screen.
• Calc
ulation Type — Select from the pick list. Specifies whether the range calculation is to
be done based on Average or Consecutive values.
• Conse
cutive Value Count — Select how many consecutive values to consider at once
for a range calculation. Typically the larger the number here, the less “flutter” in reporting
threshold crossings.
• Emit Notification — Check to emit an event if the device crosses the configured
threshold
(s).
• Apply
to Series — Check to enable on composite attributes only. Checking this applies
the threshold to individual elements within the series. When it is unchecked, the threshold
applies only to aggregate measurements (the overall value of the series), not individual
elements within the series.
For example; a Key Metric monitor for CPU utiliza
tion on a device with two CPUs actually
monitors both CPUs. When unchecked, the threshold applies to the average of both
CPUs, when checked, the threshold applies to each individual CPU.
Tip: W
hen you check this, you can also apply thresholds to regular
expressions. This is useful to monitor components within components,
for example cores within a CPU.
Click Apply to preserve your edits, or Cancel to abandon them.
The threshold interval editor pops up when you select the Add button or the Edit icon to the
right of a threshold’s row in the threshold attribute editor.
