The easy and dirty way is to query the manager application and grab the current session, running threads and other vars you are interested in. Be warned the manager application is not so easy to parse. The correct path instead is to use JMX. JMX can be used to monitor all aspect of tomcat, like threads, sessions, etc. etc. If you use a jdk >= 1.5 then start adding -Dcom.sun.management.jmxremote to your JAVA_OPTIONS and then look at http://java.sun.com/j2se/1.5.0/docs/guide/management/agent.html and http://java.sun.com/jmx for details. There is already a nagios probe to get data via jmx http://www.nagiosexchange.org/cgi-bin/page.cgi?g=2338.html;d=1 I personally use the lambda probe application to monitor my tomcat farm from nagios. It is way too easy to parse.
