Oracle GlassFish Server 3.0.1 Administration Guide

ProcedureTo View Comprehensive Monitoring Data

Although the monitor subcommand is useful in many situations, 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 subcommands 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 about the object. See To Enable Monitoring if needed.

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

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


    asadmin> list --monitor "*"
server.web
server.connector-service 
server.orb 
server.jms-serviceserver.jvm
server.applications
server.http-service
server.thread-pools

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