[hobbit] RE: multiple http test

[Klomp, H.]

What I did to monitor a host with multiple web servers (where all the web servers have there own IP address) is to put a subpage with all the hostnames and doing a http check for these hosts.

An other possibility is to test multiple webpages at one http test and have that test display the different hosts. In the bb-hosts file you have a line like
0.0.0.0 server  #  http://servicedesk http://ictdesk http://solve
Which will display at the http test as

 http://solve/ - OK

With cont tests, if the http query is unable to be made, then the http test
will be red & the cont test will be clear. So your description of the
situation is the way that Hobbit works.

I also have servers that run 10+ apache instances, and it is difficult to
monitor all http URLs. What I did was create a monitoring device for each
apache instance. So I keep server level tests with the server device & all
apache tests with the apache device entries.
