check_nrpe CheckCounter

hi,

at Nagios 2014 R 1.0, paging file service is failed as the following:-

COMMAND: /usr/local/nagios/libexec/check_nrpe -H 10.100.20.194 -t 120 -c CheckCounter -a 'Counter=\\\\Paging File\(_Total\)\\\\% Usage' MaxWarn=85 MaxCrit=95 ShowAll
OUTPUT: CRIT: Counter not found: \\\\Paging File\(_Total\)\\\\% Usage: Unable to connect to specified machine or machine is off line. (800007D0)

The "Test Command" feature in the CCM will not work in all cases (especially extreme escaping required with performance counters), it is there for simple testing. Also, you should have " instead of ' around the arguments

Can you run the following from the XI command line?

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H 10.100.20.194 -t 120 -c CheckCounter -a "Counter=\\Paging File(_Total)\\% Usage" MaxWarn=85 MaxCrit=95 ShowAll

[hanya.radwan]

it gives the following error from nagiosxi:

CRIT: Counter not found: \\Paging File(_Total)\\% Usage: Unable to connect to specified machine or machine is off line. (800007D0)

and when run command from nagios server, gives the following result:
[root@nms ~]# /usr/local/nagios/libexec/check_nrpe -H 10.100.20.194 -t 120 -c CheckCounter -a "Counter=\\Paging File(_Total)\\% Usage" MaxWarn=85 MaxCrit=95 ShowAll
OK: \Paging File(_Total)\% Usage: 16.1407|'\Paging File(_Total)\% Usage'=16.140747;85;95

So from the command line it is working correctly.

Can you show us the command definition as well as what you have in $ARGn$ for the service.

This should allow us to help you adjust it down to the correct settings.

define service {
service_description Page File Usage
use xiwizard_nrpe_service
hostgroup_name RBT
servicegroups ALL
check_command check_nrpe!CheckCounter!-a 'Counter=\\Paging File(_Total)\\% Usage' MaxWarn=85 MaxCrit=95 ShowAll!!!!!!
max_check_attempts 5
check_interval 5
retry_interval 1
check_period xi_timeperiod_24x7

notification_period xi_timeperiod_24x7
notification_options w,c,u,r,f,s,

contact_groups RBT

}

and this the command :$USER1$/check_nrpe -H $HOSTADDRESS$ -t 120 -c $ARG1$ $ARG2$

The only real difference I see between your commands is the use of double quotes in your cli execution, and single quotes in the command definition. While I don't feel it should make a difference, let's try running it from command line the other way as well. Please return the output of these two commands:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H 10.100.20.194 -t 120 -c CheckCounter -a "Counter=\\Paging File(_Total)\\% Usage" MaxWarn=85 MaxCrit=95 ShowAll
/usr/local/nagios/libexec/check_nrpe -H 10.100.20.194 -t 120 -c CheckCounter -a 'Counter=\\Paging File(_Total)\\% Usage' MaxWarn=85 MaxCrit=95 ShowAll

Is your machine having network issues or something? I would have expected to see an error relating to not finding the performance counter, not that your machine is offline. If the top command repeatedly fails, and the bottom one repeatedly works, let us know, but I would suggest trying them both a few times and making sure that the offline error is not specific to single quotes.

greate it is Ok after use double qutes

[sreinhardt]

Awesome! I will lock this up then.
