ServiceCheck.HTTP offending port value in the Host header
« on: November 24, 2012, 10:52:33 am »

I've been struggling a bit with monitoring a particular Wordpress site, I kept getting a 301 redirect all the time from the site with ServiceCheck.HTTP, I finally figure it out after some TCPDumping of the traffic, the request from ServiceCheck.HTTP looks like this:

Code: [Select]
GET / HTTP/1.1
Connection: close
Accept: */*

The additional :80 in the Host header seems to be causing the problem, as soon as i modified the source code for the portcheck subagent in: netxms-1.2.4/src/agent/subagents/portCheck/http.cpp to exclude the port value, the Wordpress site stopped redirecting me and instead showed the HTML output of the site.

I'm not sure what the solution should be and this probably is a Wordpress specific issue, but I'd love to see an option to specify and have the possibility to override what HTTP headers are sent to the target.
