Since this is an application in production, i cannot add in any instrumentation to enable JConsole or JMX information. What i have currently to work with is the Tomcat status at page http://:8009/status/status and that has information like : jk-8009 Max threads: 400 Min spare threads: 375 Max spare

What is the best w
