Meta Syntax —Further refine the variable type with the pick list. For example, you can select
Counter32 (a 32-bit counter). For Counter types, the monitor computes change from
previous readings, and for Gauges it does not.
NOTE:
If a message appears saying: “Device fault: Return packet too big” in the Monitor Status Summary, then
you have selected too many SNMP attributes to poll in a single request. Please modify your monitor to
request smaller numbers of attributes
Scheduling Refresh Monitor Targets
Because monitors can address targets that are members of dynamic groups, refreshing these ensures
that group memberships are up-to-date. To do this, you can create or alter the schedule for Monitor
Target Refresh. When executed, this updates monitors with groups as targets based on current
memberships. This removes targets no longer members of a monitored group and adds new group
members. A seeded schedule refreshes these every six hours, by default.
Tip
You can also
Refresh Monitor
manually by right-clicking in the Resource Monitors table.
Top [Asset] Monitors
Dell OpenManage Network Manager uses seeded, default Active Performance Monitors (APM) to
display performance data in several categories. These portlets display the summary results of device
monitoring, for example, the devices slowest to respond to ping.
