How to monitor complex websites?

[Oliver Marshall]

Call me silly, but, for monitoring each server, can't you just assign
each server its own IP (if each hasn't already got one), and then
monitor the response on those IPs? 

We have a four server cluster (windows based) that operates using RRDNS,
and each has it's own IP (clearly), and on each we have the NSClient and
test various things locally, as well as pinging the IP's and checking
the individual http ports on each.

check_http version 1.89 (which comes with nagios-plugins 1.4.3) can set
a 
User-Agent-String:

 -A, --useragent=STRING
   String to be sent in http header as "User Agent"

But there's a problem with agent-names like "Mozilla/4.0 (compatible;
MSIE 
6.0; Windows NT 5.1; .NET CLR 1.1.4322)" - nagios didn't like the
semicolon 
';'. It seems, that everything after it is ignored (like a comment).
One solution for this can be to define a own macro (e.g. $USER3$) with
the 
escaped semicolon and then use this macro within the agent name, this
should 
help.

e.g.:
in resource.cfg:
$USER3$="\;"

in commands.cfg:
command_line    $USER1$/check_http -H $HOSTADDRESS$ -A "Mozilla/4.0 
(compatible$USER3$ MSIE 6.0$USER3$ Windows NT 5.1$USER3$ .NET CLR
1.1.4322)"

But probably you should make your own plugin if you need special cookie 
support.

bye, Rene
