Hi You will probably get better answers by asking on the tomcat users list. See tomcat.apache.org.
Tomcat publishes its health statistics using jmx and if your developers were thorough it is likely that application statistics would also be available in jmx. There is a number of expensive and not so expensive commercial tools to setup monitoring for jmx. Tivoli and AppManager comes to mind. I believe there might be support for jmx monitoring in cacti so that would be worth googling. Other than that a good test would be to monitor output of a wget request to your tomcat server which gives a good indiction of the health of your application server.
Also have a look at http://www.lambdaprobe.org/d/index.htm which is a tool to monitor multiple tomcats with.
OpenNMS can monitor jmx values (as well as snmp and doing icmp and httpd probes, etc.). http://www.opennms.org.
