[Nagiosplug-devel] check_http feature for web cluster

[Aurimas Mikalauskas]

Hello,

I'm missing one feature in check_http nagios plugin that would help
monitoring different virtual hosts on clustered web servers. The
situtation is simple:

I have two virtual hosts www.first-host.com <http://www.first-host.com> and
www.second-host.com <http://www.second-host.com>
both round-robin resolving to 10.0.0.1 <http://10.0.0.1>,
10.0.0.2<http://10.0.0.2>and
10.0.0.3 <http://10.0.0.3>.

I want to check each virtualhost on each cluster. If I do
./check_http -H www.first-host.com <http://www.first-host.com>

then it will likely round-robin each check to a differend cluster and
most likely at least one of them will be alive and return correct
data.

If I do "./check_http -I 10.0.0.1 <http://10.0.0.1>" then I will be able to
check only
the first virtual host.

If you added one more variable that is the virtual host (even if I use
-I 10.0.0.1 <http://10.0.0.1>) somewhere near 824 line after the "Host: ",
the plugin
would be much closer to perfetct. On the other hand, you could simply
expand the <uri> variable so it could be used as "http://virtualhost/uri".

Thank you in advance for your good work!

Respectfully,
Aurimas Mikalauskas
