I have a link that looks like this http://hostnae:8080/login.jsp (I edited
the actual link on purpose) and I need to monitor that it is sending data
correctly when looking at it. I used the check_http command like this.
status:/var/www# /opt/nagios/libexec/check_http -H 10.3.8.41 -u
http://hostnae:8080/login.jsp
HTTP CRITICAL: HTTP/1.1 500 Internal Server Error
However I know that when I go to that in a browser it pops up fine. Anyone
know of a solution to this? Is there a special plugin or command I can do
for a .jsp file? I looked for a plugin and I could only find "webinject"
which doesn't seem to work with Nagios.
You might want to try something like the attached Python script. It uses
the lynx browser to get the page and search for a magic phrase. It's
just a sketch but should give you an overview of another feasible
approach to do HTTP checking.
