a: Simply use the check_http plugin and supply the port as 8080. I assume
that's what your tomcat instance listens on.
b: Use either check_snmp or use check_disk plugins to accomplish these.
c: Not sure if you can do this. I certainly don't know of any Nagios plugins
that will do this for you. Maybe tomcat exposes this information via JMX or
something similar, but I'm not too up on that. Either way you're going to be
writing your own plugin to monitor it.

For how to use each of the mentioned plugins, simply run them with the -h
switch and go from there. Most are extremely self explanitory.

Rob.


Please let me know whether all these scenarios supported by nagios or not ?
