2 BEA WebLogic Managed Server

Oracle Enterprise Manager can be used to manage BEA WebLogic Managed Servers. You can use the All Metrics page for an BEA WebLogic target to view the metrics that have been collected for that target by the Oracle Management Agent.

2.1 Active Applications

This category of metrics provides information about the active applications. The following table lists the metrics and associated descriptions.

Note:

For all target versions, the collection frequency for each metric is every 15 minutes.

Table 2-1 Active Applications Metrics

Metric Description

Current Client Processing Time

Amount of time taken to execute the servlet during the last interval

Active Invocations

Number of active invocations

Active Sessions

Number of active sessions of the application

Active Response Time

Average execution time of the application. The average response time of an application is calculated by dividing the number of active requests generated between two consecutive time intervals (that is, the time when the agent collects the data from the server), by the time taken for processing these requests.

Total Time

Time taken to execute all invocations of the servlet from the time of its creation


2.2 Active JDBC Connections

Should be true if you want EJBC to keep its generated source files, and false if you want EJBC to delete them after compiling

Persistence Enabled

Sets the persistenceEnabled attribute of the ConfigurationMBean object

URI

Returns a URI pointing to the application component, usually on the Administration Server


2.8 EJB Component Runtime Metric

This category of metrics is a top level interface for all runtime information collected for an EJB module. The following table lists the metrics and associated descriptions.
