Thank you - that's helping as I can now successfully identify text in either the header or the content, but can anyone confirm the correct syntax for specifying the URL as when I do this:
./check_http -H MyHost -u MyURL --expect=301 -s "Document Moved" -v
I get an OK, but when I add a trailing "/" to the URL, I get a Critical
Thanks all, and have a good weekend.

The trailing slash thing depends on the web server. With Apache,
mod_dir is usually the culprit here:

OK, So here's what I have:
Code: Select all
define command{
command_name check_http_url
command_line $USER1$/check_http -I $HOSTADDRESS$ -u $ARG1$
}
define host{
host_name URL1
hostgroups 000-URL1
address www.MyURL.com/
max_check_attempts 5
check_period 24x7
contact_groups admins
notification_period 24x7
}
define hostgroup{
hostgroup_name 000-URL1
alias Website Checking
}
define service{
use generic-service
host_name URL1
service_description URL1 + Text [Country of Residence] + Status [301]
check_command check_http_url!URL1 -u /blah/blah/system/ -s "Country of Residence" --expect=301
#register 0
}
returns "Name or service not known"
Any offers?
As always, thanks for your help.

Your Service's
check_command is malformed:
Code: Select all
check_command check_http_url!URL1 -u /blah/blah/system/ -s "Country of Residence" --expect=301
Drop the "URL1" since it doesn't fit into your command definition. It's just hanging out there. Also remove the
-u argument since your Command definition is already including it.
Code: Select all
check_command check_http_url!/blah/blah/system/ -s "Country of Residence" --expect=301
Also remove the preceding slash from your Host's
address definition.
www.MyURL.com should be sufficient (especially if you're including the preceding slash in your URL path).

Thank you for coming back to me.
So now I have:
Code: Select all
define host{
host_name URL1
hostgroups 000-URL1
address http://www.yada.dev.com
max_check_attempts 5
check_period 24x7
contact_groups admins
notification_period 24x7
}
define service{
use generic-service
host_name URL1
service_description MyServiceDescription
check_command check_http_url!/my/sub/folder/ -s "Country of Residence" --expect=301
#register 0
}
So, I'm testing for the presence of the text string "Country of residence" in "
www.yada.dev.com/my/sub/folder"
But its STILL showing "Name or Service not known"
Sorry to be a nuisance!

Oh pete, you're not a nuisance
Your Host definition's
address should not contain
http://. See if removing that does the trick!

No luck, I'm afraid - just to recap:
Code: Select all
define command{
command_name check_http_url
command_line $USER1$/check_http -I $HOSTADDRESS$ -u $ARG1$
}
define host{
host_name URL1
hostgroups 000-URL1
address MyURL.dev.com
max_check_attempts 5
check_period 24x7
contact_groups admins
notification_period 24x7
}
define service{
use generic-service
host_name URL1
service_description URL1 - URL1/my/folder/structure + Text [Country of Residence] + Status [301]
check_command check_http_url!URL1/my/folder/structure/ -s "Country of Residence" --expect=301
#register 0
}
Within the service, I have tried both "URL" and the name of the actual url to which it refers, but both return "Name or service not known".
Maybe Core just isn't meant to be able to monitor a URL without a server hostname to attach it to (he finished, desperately)?
And yes, I AM a nuisance! Perhaps I should ask Core to resolve complex quantum mechanics equations and explain the meaning of life while I'm at it..!

Your check_http_url command definition seems to have switched back to using
-I instead of
-H. Try changing it like so:
Code: Select all
define command{
command_name check_http_url
command_line $USER1$/check_http -H $HOSTADDRESS$ -u $ARG1$
}

NOW we're getting somewhere.
The following:
Code: Select all
define command{
command_name check_http_url
command_line $USER1$/check_http -H $HOSTADDRESS$ -u $ARG1$
}
define host{
host_name URL1
hostgroups 000-URL1
address MYURL.uat.com
max_check_attempts 5
check_period 24x7
contact_groups admins
notification_period 24x7
}
define service{
use generic-service
host_name URL1
service_description
check_command check_http_url!URL1/My/URL/name/ --expect=301
}
returns:
HTTP CRITICAL - Invalid HTTP response received from host: HTTP/1.1 400 Bad Request
which is a bit further on than I was yesterday.
Thanks for your continued patience.

Your Service's check command seems to have changed between posts. It no longer includes a preceding slash for the URL:
Code: Select all
check_command check_http_url!URL1/My/URL/name/ --expect=301
Try giving it a preceding slash like so:
Code: Select all
check_command check_http_url!/URL1/My/URL/name/ --expect=301
