Security is an issue with snmp for this client, even v3 is not good enough for them :-(.

Right now just doing that, but it does not verify if the application on that port is working tho. Only the port is open.

Good point, will look into this.

Yup, monitoring port 8888, but the flaw with this is that it doesn't tell if tomcat application is doing ok, only the port 8888 that talks to tomcat is doing ok.

Seems reasonable to do this.
Many thanx for your input.  Love the nagios mailing list ;-).

I wonder if anyone has any a pointer, url, etc on Tomcat monitoring via
Nagios.

Thanx and regards,
