What I want now is to customize my email alerts with a detailed messages. I need to send alerts for my tomcat logs along with the stack trace.

I have configured Nagios 3.4.4 on CentOS 6.3 Final. I have also configured Postfix with SMTP email server. I have verified from console that I am able to send email notifications and recieved them on designated address.

Nagios is configured to send notify-host-by-email and notify-service-by-email.

I have a Nagios server which monitors many servers. From time to time we encounter an error which cannot be resolved at the time and we are leaving it for the time being. When it happens, we keep getting email notifications regarding the failing service. So if we're not dealing with the problem in the next day - we receive about 500 email notifications regarding it.
