Hi; I attended to an Oracle IAS event and they presented their Enterprise Manager 10g, and they showed some great monitoring capabilities. Here I quote some of them from their document "http://www.oracle.com/technology/products/oem/pdf/wp_aslm_10g.pdf":
"The tracing functionality provides an on-demand tool that lets administrators examine in detail all invocation paths of a transaction, and isolate the exact tier and location of a problem. All invocation paths of a transaction are traced and hierarchically broken down by servlet/JSP, EJB, JDBC/SQL times. Further drill-downs into each component identify response time breakouts by invocation path. Click-to-SQL drill-downs allow administrators to navigate down from a transaction view and examine the underlying SQL statements." (Page 6) "URL processing time and load activity graphs provide administrators with information on the impact of server activity on response times." (Page 7) "Enterprise Manager provides correlation of CPU utilization, memory, and I/O usage of all Web application components to help administrators determine where resources are constrained." (Page 8) Well, my question is if there is any way to do such (or any) monitoring with Tomcat 5.5.17. If not, is there any monitoring tool that you guys use to monitor and troubleshoot Tomcat? Maybe just tomcat/java commands that shows status/monitoring info. Actually we only graph URL response times and load keep an eye on the logs. Any info is welcome. Thanks a lot.
