NRPE:Command 'check_uptime' not defined

[gsivaa]

Hi Folks,

I am using nagios recently.. when i try to configure the nagios for the Linux client machines, i got up with the error message on the nagios window:
[*NRPE: Command 'check_uptime' not defined]

In the Nagios Monitoring server under the path /usr/local/nagios/etc/services.cfg

Code: Select all

define service{
use                          local-service
host_name               testserver
service_description   uptime
check_command       check_nrpe!check_uptime
notification_interval  30
notification_period    30
 

And under the /usr/local/nagios/etc/objects/command.cfg

Code: Select all

#check_uptime command definition
define command {
command_name     check_uptime
command_line        $USER$/check_uptime  -H $HOSTADDRESS$
}

The "check_uptime" command must be defined on the client (remote machine that you want to monitor). For example, in the nrpe.cfg you may have something like this:

Code: Select all

command[check_uptime]=/usr/local/nagios/libexec/check_uptime

Then you call it by running the following command on the Nagios server:

Code: Select all

./check_nrpe -H <client ip> -c check_uptime

Hi

I have already input in the file /usr/local/nagios/etc/nrpe.cfg

Code: Select all

command[check_uptime]=/usr/local/nagios/libexec/check_uptime -w 3 -c 5

and restarted the xinetd service

then when I check in the nagios servers , i got the error message like below:

Code: Select all

./check_nrpe -H <client_ipaddr> -c check_uptime
NRPE: Command 'check_uptime' not defined

Does NRPE run under xinetd on the client or as a "standalone" daemon?

What is the output of the following commands, run on the remote box?

Code: Select all

ps axuw | grep nrpe
netstat -at | grep nrpe
/usr/local/nagios/libexec/check_uptime -w 3 -c 5
find / -name nrpe
uname -a
cat /etc/*release

After making changes, did you run service xinetd restart? This will help make sure your configurations are saving.

Hi,

Yes i have restarted the service and the same error message is occurring on all the servers i have configured...

[rkennedy]

What is the output from this?

Code: Select all

netstat -nap | grep 5666
