WebLogic Data Collection
Figure 1-2 shows how the PATROL Console interacts with the PATROL
Agent on a WebLogic administration server. Performance data is
maintained by BEA WebLogic using JMX Mbeans. This data is then
collected by a Java-based PATROL collector and returned to PATROL via
a PATROL Script Language (PSL) pipe. Profiling data on J2EE objects
(like EJBs, SQL, or servlets) uses the JVMPI interface to communicate
with applications running on the server.
