Retain availability data to enabled alarms. If you define thresholds, you should
retain availability data.
Retain availability data stores the Boolean values of whether availability data was in the range
your defined metrics.
Retain calculated data complements Retain polled data . If checked, it stores the calculated

Monitor Entities
Click Add or Add Group to select, in a subsequent screen, entities this monitor will poll. In the
SNMP Interfaces screen, you can also filter target interfaces with
Add Filter / Edit Filter. This
opens a standard OpenManage Network Manager filter screen where you can configure how to
target the interfaces within a selected group or device
. See Chapter 28, Filters for details.
Click
Remove to delete a selected entity from the list. The targets for monitors can be members of
groups. To ensure the membership of these groups is current, you can create or edit a scheduled
refresh of the target groups as described in Scheduling Refresh Monitor Targets on page 799.
NOTE:
When you select equipment with large numbers of Monitor Entities, for example a device with 1,000
interfaces, even loading the list from which to select may take a long time.
Monitor-Specific Configuration
The type of attribute polled depends on the type of monitor selected. The lowest portion of the
screen reflects the monitor type you have selected. For SNMP monitors, you can
Browse to open
the OpenManage Network Manager MIB browser, and select attributes that way, or you can
Add to
open an editor with SNMP attribute parameters that you can fill in. See SNMP Attributes
(Interfaces or Scalars) on page 793 for details.
