Betreff: [Nagiosplug-help] check_squid.pl cannot run in Nagios ;works from the CLI

Hi,

    I have just installed Nagios on a new system for testing purposes. 
I have downloaded a plugin and copied it into
/usr/local/nagios/libexec/check_squid.pl

The script is available from here: 
http://exchange.nagios.org/directory/Plugins/Websites%2C-Forms-and-Transactions/Squid-Web-Proxy/details
Or from tinyURL:  http://tinyurl.com/yzt8g2o

I have created a service:
define service{
        use                             remote-service         ; Name of
service template to use
        host_name                       fredprox
        service_description             SQUID
        check_command                   check_squid
        notifications_enabled           0
        }


I have created a command:
# 'check_squid' command definition
define command{
        command_name    check_squid
        command_line    $USER1$/check_squid.pl -u http://www.google.com
-p fredprox -l 8080 -e200
        }



If I run the script from the command line I have:
# ./check_squid.pl -u http://www.google.com -p fredprox -l 8080 -e200
OK - Status: 200 OK


However, using it from within Nagios causes the error:[1260361223]
EXTERNAL COMMAND: ENABLE_HOST_SVC_CHECKS;demeter
[1260361245] EXTERNAL COMMAND:
SCHEDULE_FORCED_SVC_CHECK;demeter;SQUID;1260361244

[1260361433] SERVICE NOTIFICATION:
nagiosadmin;demeter;SQUID;CRITICAL;notify-service-by-email;(null)


I have set debugging to 128, but nagios.debug is empty.

I expect that I do not have a clear understanding (or any understanding)
of the plugins, and find the documentation bewildering, to be frank :(

Perhaps, it has something to do with the $USER1$ specification in the
command, but I could not find any documentation about this and what it
was used for.

Does anyone have any advise, or even the answers?

Best regards, J.
