Tomcat Application Server adding a plugin

I am working on adding a snmp plugin (SNMP4J) to the Tomcat Application Server. What area of the application server I should be looking into to get this done? In other words, any specific class or directories that I should be looking into for making any modification. If not for this snmp plugin is there any other way of having a snmp manager run on the Application Server? I would greatly appreciate your help on this.

Welcome to the JavaRanch!

I'm guessing that you want to provide SNMP agent functionality. It's been a while, but I think there's actually some SNMP support built into the JVM, so you might want to check that.

SNMP agents are free to present whatever MIBs they wish, but they won't just invent MIBs, so excluding whatever SNMP support the JVM gives you (if any), you're on your own.

There are several ways I could spin this. With Linux/Unix net-snmp, I'd probably write a small agent app as a net-snmp plugin and have that app query the Tomcat server, possibly using JMX as the java-to-java transport and then having the SNMP agent translate JMX data to MIB form. You could also query the webapps using some sort of web services or REST query facility.

Actually putting SNMP code into the webapps would probably not be as flexible.
