Overview of Monitoring
To monitor the Enterprise Server, perform these steps:
1. Enable the monitoring of specic services and components using either the Admin Console
or the asadmin tool.
For more information on this step, refer to
“Enabling and Disabling Monitoring” on
page 191
.
2. View monitoring data for the specied services or components using either the Admin
Console or the asadmin tool.
For more information on this step, refer to
“Viewing Monitoring Data” on page 193.
About the Tree Structure of Monitorable Objects
The Enterprise Server uses a tree structure to track monitorable objects. Because the tree of
monitoring objects is dynamic, it changes as components are added, updated, or removed in the
instance. The root object in the tree is the server instance name, for example, server. (In the
Platform Edition, just one server instance is permitted.)
The following command displays the top level of the tree:
asadmin> list --user adminuser --monitor server
server.applications
server.http-service
server.connector-service
server.jms-service
server.jvm
server.orb
server.resources
server.thread-pools
The following sections describe these sub-trees:
