Active Performance Monitor 759
- Thresholds—A collected value or a derived metric supports defined value ranges. Charts reflect
these defined ranges when plotting data. The application may generate threshold alarms
when the current value(s) falls in a different range than previous value(s). You can configure
an average over n values or n consecutive values for range assessment.
You can retain range results to support trending. For example, how often an interface has been
overused.
-
Fault handling —If the monitor fails to determine reachability, the application generates an
appropriate alarm. If the monitor fails to collect all the data as configured, the application
generates an alarm.
SNMP Performance Monitoring Example
You can actively monitor performance, as described in this section, or you can monitor event and
alarm activity. To set up a performance monitor, follow these steps:
1 Create an SNMP Monitor
2 Create a Dashboard View
3 Install a Monitor in the View
NOTE:
You can use the standard SNMP Interfaces: Performance Monitor - Bandwidth to make capacity
planning decisions, and be proactive in configuring your network.
Create an SNMP Monitor
1 Open the Active Monitoring -> Monitor manager, and create a new monitor with action ->
New
, or edit an existing SNMP monitor.
2 Select the type of monitor in the next screen. For this example, we create an SNMP
Interfaces: Performance Monitor - All
monitor. Consult the online help for more specific
instructions about other types of monitors. This monitor can be a template for other,
modified monitors.
