Escaping broke i 3.1.1 ?

[Mathew Walker]

I think you may need to escape the backslash itself with another backslash ... vaguely recall having to do that myself in some checks when passing values that had a backslash in it.

Hello,

Sorry for double posting, but wrong subject.



Ton:

Command line:
/nagios/libexec/check_nrpe -H <X> -c CheckServiceState -a AOS\$01 ShowAll=long
OK: AOS$01: started

Here is the host def:
define host {
use                     X

host_name               X
address                 X
alias                   X


hostgroups              +CRM4

#max_check_attempts     3
#check_interval         2
#retry_interval         1

#contact_groups         +
#notifications_enabled  1

_CRM_SERVICES           AOS\$01

# Macros
_REQUESTOR

}

The service definition:
define service {
# Which _template_* to use.
# (e.g. standard-service-60)
use                             standard-service-1

# Service spesific
service_description             CRM Services

check_command                   check_nrpe_parameters!CheckServiceState!ShowAll=long $_HOSTCRM_SERVICES
hostgroup_name                  CRM4

# Per service options
first_notification_delay        10
process_perf_data               0
notifications_enabled           1
max_check_attempts      2
retry_interval          5
}

The check command definition:
define command {
        command_name check_nrpe_parameters
        command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -t 15 -c $ARG1$ -a $ARG2$
}


It worked on Nagios 3.0.6. I've tried almost any combination of escaping the dollar sign, $$, \$, \\$$,\\\$.... You name it!

Thanks for your help,

Tore

Tore,

Can you send the configuration for the host and service too? Can you
also send the check_nrpe_parameters command definition.

On the command line, what works?

Also, you said a previous version of Nagios worked with this
definition - which version of Nagios was that?
