Attributes available depend on the type of monitor you are creating. Notice that you can also
check to make crossing this threshold emit a notification (an alarm that would appear on the
Alarm panel). You can also configure the type of calculation, and so on. You can even alter
existing thresholds by selecting one then clicking Edit to the right of the selected threshold.
10
Click Apply for each threshold interval you configure, then Apply for the entire threshold
configuration.
NOTE:
If a threshold’s counter is an SNMP Counter32 (a 32-bit counter) monitoring can exceed its capacity with a
fully utilized gigabit interface in a relatively short period of time. The defaults configured in this monitor
account for this, but if you know that this is an issue, you can probably configure the monitor to account for
it too.
After taking a look at Thresholds no more configuration is required. Notice, however, that you
can also configure Calculated Metrics , Inventory Mappings and Conditions on other screens
in this editor to calculate additional values based on the monitored attributes, to map them,
and to make conditional properties based on monitored behavior.
Tip
Calculated Metrics
is particularly valuable if you want to monitor a composite like ifIn ifOutErrors
or want to calculate a parameter like errors per minute when you have a 5-minute monitoring interval.

Click Save and the monitor is now active.
Notice that the Availability icon appears at the top of a Monitor Status Summary snap panel
in the Expanded Resource Monitor next to a time/date stamp of its last polling. Right-click
the monitor and select Refresh Monitor to manually initiate polling.
Values displayed in the Overall Availability column of the Monitor Manager do not
automatically refresh and may be out of date. The Reference Tree snap panel maps the
monitor’s relationship to its target(s) attribute(s) and other elements. The Details snap panel
summarizes the monitor’s configuration.

For information about having the monitor’s results appear in the a Dashboard portlet, see
Dashboard Views on page 277.
