Active Performance Monitor

This chapter describes Active Performance Monitor. This application’s capabilities include

configuring Monitors that receive device performance information, Dashboard View Managers that

display that information, and Retention Policies that describe how to archive that information. The

following sections describe those capabilities in detail.

NOTE:

See the Administration Section for advice about setting up and configuring performance monitoring, and

about configuring a separate database for more responsive performance monitoring.

Active Performance Monitoring (APM) lets you retrieve data from a managed entity and evaluate it

against various criteria. This lets you determine health and availability of that equipment. With

this application, you can regularly poll critical health characteristics from multiple sources to

immediately identify problems with IT devices, networks and services. It also lets you test and

identify transactional problems with application & network services.

Advanced monitoring capacities provide domain-specific monitoring of both availability and

performance. Monitors isolate key health attributes and characteristics for IT devices, networks and

application/network services.

APM stores collected data in a central database and retains it according to a configurable policy

(see Creating or Updating a Retention Policy on page 788).

You can display the data collected from monitors by creating graphs and charts. You can also retain

it (roll it up) in historical tables. These historical tables hold summaries of the data at various fixed

intervals or periods.

Events and alarms can report on a monitor's execution. Monitors report failures as events so

operators can see when certain devices are not behaving as expected and why. Events may also

report changes in health or availability for an individual device or service.

Some major features of this capability include the following:

• Management of monitoring configurations

• A dashboard view where you can see both current and historical data,

• Management for historical data's roll-up and retention

• Using current and historical data for reporting.
