ping.jsp is empty, Xymon considers this an error 🔗 link

The applications we're testing use an empty ping.jsp page.  Xymon considers
no content an error.  I tried setting httpstatus;URL;0|2..;3..|4..|5..|999
but that hasn't worked.  (Other than adding text to the ping.jsp page) can
anyone make any recommendations on how to avoid this and still test the
URL?

Perhaps the "nocont" test can do what you need.  Add "nocont;URL;." to a
host def to alert if the response is not empty.

No, it doesn't - you must have some other problem. Have a look at the Xymon demo website, specifically the "henrik.hswn.dk" webtest on the "Services" page - http://www.xymon.com/xymon-cgi/svcstatus.sh?HOST=henrik.hswn.dk&SERVICE=http

This is a simple web check of an empty webpage (you can see the "Content-length: 0" header), and the "200 OK" result the the webserver provides is enough for Xymon to flag this as "green". In hosts.cfg, it is simply

0.0.0.0	henrik.hswn.dk	# http://henrik.hswn.dk/empty.html

So either you have your test definition setup incorrectly, or your ping.jsp page does not return a valid HTTP response. Try fetching the URL with a tool like "curl", or even a plain "telnet":

$ telnet henrik.hswn.dk 80
