Nagios HTTP Checks...

[john.1209]

My question is how to optimize Nagios HTTP checks?

My Nagios instance is monitoring HTTP and displays the following error, yet the web server is operational.

HTTP CRITICAL: HTTP/1.1 500 Internal Server Error - 5640 bytes in 0.003 second response time

How to resolve? Thanks in advance.

I would probably check the logs on the web server and try to work out why it is returning error 500, you can also run check_http (found in /usr/local/nagios/libexec) from the command line to help debug the problem and see all the options available for the check.
