Cool :-) Btw, If you care about monitoring that much, you should consider using something more powerful. Something that can give you more info than just up/down, but also average request duration, amount of errors in last 1/5/15 minutes, number of requests and that sort of stuff.

That's because my clients don't connect directly to the tomcat server, they have load-balancer/proxy stuff in the middle. I can do a local client polling every 1sec but that's too invasive, I'm happy with the timestamp Tomcat thinks it's up. :) --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
