With Silk Performer the following IBM WebSphere Application Servers can be monitored:
IBM WebSphere Application Server Advanced Edition 3.5
IBM WebSphere Application Server Advanced Edition 4.0
IBM WebSphere Application Server 4.x via Performance Servlet
IBM WebSphere Application Server 5.0 via Performance Servlet
Monitoring IBM WebSphere Application Servers 3.5 has been tested under NT, Win2000 and Ret Hat Linux platforms. Monitoring IBM WebSphere Application Servers 4.0 has been tested under NT and Win2000.
Typical performance measures for WebSphere Application Servers 3.5:
Runtime Module: Contains performance counters related to the Java Virtual Machine
Thread Pool: Answers questions like how many threads are currently active or how many threads were created, this includes idle and active threads.
Bean Data: Specific performance information about deployed EJBs. For example how many beans were created or the response time of method invocations.
Transaction Data: Contains everything about transactions like how many transactions are currently in progress or the average time it takes to execute one transaction.
Connection Manager:Contains performance counters for JDBC connections.
Servlet Engine: Contains performance counters giving an idea how deployed servlets and JSPs perform.
Typical performance measures for WebSphere Application Servers 4.x:
BeanModule: Specific data about deployed EJBs. For example how many beans were created.
ConnectionPoolModule:This module contains performance counters about JDBC connections like how many JDBC connetions are currently in the pool.
JvmRuntimeModule:Java Virtual Machine specific performance counters.
ServletSessionModule: This module contains performance counters about servlet sessions. For example how many sessions are active or the average session live time.
TransactionModule: This module contains performance counters giving information how many transactions are in progress or the average time it takes to execute one transaction.
WebApplicationModule: Provides information about deployed servlets and JSPs. For example the average time it takes the servlet to process requests.
