Re: How to monitor Tomcat Server.
Nagios is overkill for one app, or even a small network. I'd suggest other OSS projects like monit or zenoss (full network monitoring). I configured Nagios for a small hosting group and loved what it could do, but no one on the planet would say it is easy to set up if you've never done it before. I've used monit for years. Easy configuration. EXTREMELY EASY. Great documentation. It will email you status messages and restart the service/process if desired. It has a web interface. It has a VERY small footprint and uses almost no memory. I've used it to monitor a buggy Tomcat application before and I am using it now for a Resin app server ATM. I am configuring it today for a new Tomcat installation. Zenoss is a full network monitoring system which may be overkill, but check it out if you wish.

How about Nagios [1]. It can check allsort of things. And you can set it up to send email/sms notifications.

Re: How to monitor Tomcat Server.
Hi Neil, Thanks for response. It seems this is also one type of tool. Here again we have some problem ie we should monitor this tool too right ? So instead installing new tool to monitor tomcat server , is there any feature that apache group provides to inform tomcat server status ? Any help in this regard ? Thanks Praveen.

Re: How to monitor Tomcat Server.
I'd still recommend Nagios to do the monitoring, far cheaper than hiring someone to do the checking 24*7. Also you'll get an instant notification of when things go bad, rather then in 2 hours time when someone checks it. You could setup 2 instances of nagios.. get them to monitor each other and then also mirror everything that will be monitored onto each of them. You;ll get two alerts if things go bad, but that's better than none. A faq on nagios monitoring tomcat.. http://nagios.org/faqs/viewfaq.php?faq_id=310 On 5/24/07, Mark H.
