This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
I am interested in adopting a tool to measure application performance, mainly in web applications on iPlanet, and in the future JBoss. It would be nice to see where the bottlenecks are in the applications. Can anyone recommend or suggest a tool for this?
Many thanks Steve [ July 01, 2005: Message edited by: Steve McCann ]
My open source JAMon tool (Java Application Monitor), is easy to use and versatile. It is also fast enough to use in production systems which is where we want to know performance metrics the most.
It works like a stopwatch - a start and stop method. You pass a String to the start method. This string can represent anything such as a page hit, time to execute a query, or time to call an ejb. This string will show up in the JAMon report along with associated statistics such as hits, time (avg/total/min/max), and concurrency stats among others. For example: start("homePage.jsp"), start("getConnection()").
JAMon has a servlet filter which offers a no-code solution to measure performance of all of your web pages and that should work in iPlanet.
Select 'Live Demo' from the http://www.fdsapi.com link below, to see a live version of jamon that times pagehits (via the servlet filter) as well as all jdbc calls. [ July 04, 2005: Message edited by: steve souza ]
You could also look at InfraRED a tool we have built.
Here is a list of salient features. # Fully non-intrusive. No coding required by developers. # Layer-wise performance statistics summary (Web, Session, JDBC etc). # API level detailed performance statistics. # Call tree views (like in other profiler tools). # JDBC API and SQL statistics. # Last invocation statistics. # Correlation of statistics across layers. # Support for centralised gathering and presentation of performance data for one or more applications in a cluster. # Remote or local collection of performance metrics. # User-friendly web GUI. # Simplified ant-based integration with application. # Support for multiple application servers * Weblogic * Jboss * Tomcat
# Useful for applications with or without use of EJBs. # Export summary of performance statistics into Excel spreadsheets. # Very low overhead, Can be used in production environments. # Ability to save and reload snapshots.
