SunOne EJB Pools Test
This test reports statistics pertaining to the EJB pools for stateful session beans and entity beans. Use the Click here hyperlink in the test configuration page to configure the EJB groups that need to be monitored by the eG Enterprise. By default, the eG Enterprise system will monitor only those EJBs that are part of a group.
Target of the test : Any Sun Java System application server with one or more entity beans or stateful session beans
Agent deploying the test : An internal agent
Outputs of the test : One set of results for every EJB group configured or every EJB (as thee cae be).
Parameter | Description |
---|---|
Test period |
How often should the test be executed. |
Host |
The host for which the test is to be configured. |
Port |
The port number on which the Sun Java System application server is running. |
User |
A valid user name for the Sun Java System server to be monitored. |
Password |
Password for the Sun Java System server to be monitored. |
Admin Port |
The port number on which the “asadmin” tool runs. |
Server |
Name of the Sun Java System server to be monitored. |
AppServerDir |
The directory in which Sun Java System application server is installed. |
AutoDiscovery |
By default, the eG Enterprise allows administrators to configure EJB groups using the eG administrative interface, and reports metrics pertaining to every group so created. Accordingly, by default, AutoDiscovery is set to No. If you want EJBs to be discovered and monitored automatically, then select the Yes option against AutoDiscovery. When this is done, the eG agent automatically discovers all the EJBs on the Sun Java System application server, and reports one set of measures for every EJB hosted on the server. |
