ProcedureTo View Comprehensive Monitoring Data

The monitor command is useful in many situations, however, it does not offer the complete list of all monitorable objects. To work with comprehensive data for an object type, use the list --monitor and the get --monitor commands followed by the dotted name of a monitorable object.

Before You Begin

A monitorable object must be configured for monitoring before you can display information on the object. See To Enable Monitoring if needed..

  1. List the objects that are enabled for monitoring by using the list(1) command.

    For example, the following command lists all components and services that have monitoring enabled for instance server:


    asadmin list --monitor=true server.*

    Information similar to the following is displayed:


    server.web
server.jvm
server.http-service
server.applications

  2. Get data for a monitored component or service by using the get(1) command.
