Best tools to monitor Tomcat I have been very happy monitoring Tomcat with Hyperic HQ. Even if developing Hyperic HQ plugins has an initial cost, we got familiar with it and developed many JMX Mbeans + associated Hyperic plugins for the needs we had like Jakarta DBCP datasource , util.concurrent ExecutorService / ThreadPoolExecutor, JMS connections, CXF, EhCache and also monitoring business application code with an @Profiled annotation to declaratively monitor key business operations. We packaged all these JMX extras with Spring xml namespace based configuration, monitoring jsps and Hyperic plugins at http://code.google.com/p/xebia-france/wiki/XebiaManagementExtras .

JAMon - Documentation JAMon - Documentation For example, to collect statistics for all JSP pages in a Web Application, a developer would place a call to the start() method at the top of every JSP, and a call to the stop() method at the bottom. With a few minutes work the developer will have statistics for all application pages. The statistics will include number of page hits, average page execution times, and the number of users simultaneously accessing each page. The statistics can be displayed as an HTML table by calling the getReport() method, or using jamonadmin.jsp. JAMon requires no special administration accounts. Many monitoring tools require administrative accounts to install monitoring software, and to view statistics.
