About theTree Structure of Monitorable Objects
TheEnterprise Server uses a tree structure to track monitorable objects. Because the tree of
monitoringobjects 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
PlatformEdition, just one server instance is permitted.)
Thefollowing 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
Thefollowing sections describe these sub-trees:
■“TheApplications Tree” on page 172
■“TheHTTP Service Tree” on page 173
■“TheResources Tree” on page 174
■“TheConnector Service Tree” on page 174
■“TheJMS Service Tree” on page 174
■“TheORB Tree” on page 175
■“TheThread Pool Tree” on page 175
TheApplications Tree
Thefollowing schematic shows the top and child nodes for the various components of
enterpriseapplications. The nodes at which monitoring statistics are available are marked with
anasterisk (*). For more information, refer to “EJB Container Statistics” on page 176.
