Could you please try the command on the command line you use to check the remote load?
This should be something with NRPE.
Please provide the NRPE config file as well.

[tgriep]

Could you fun this command on the Nagios server and post back the results?

Code: Select all

ll /usr/local/nagios/libexec

Could you attach to this post the service check cfg files for the services that are failing?

[rlinux57]

I have attached the nrpe.cfg of remote host alongside this post.

Kindly tell me how can i check the remote host from nagios through manual command ?

Here's one example:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H remote_host_address -c check_home-disk

[rlinux57]

It shows: usr/local/nagios/libexec/check_nrpe -H HOSTNAME -c check_uptime
-bash: /usr/local/nagios/libexec/check_nrpe: cannot execute binary file

[Box293]

Your nrpe.cfg file does not have a command definition for check_uptime

[rlinux57]

But it shows in every command:

/usr/local/nagios/libexec/check_nrpe -H HOSTNAME -c check_load -w 2 -c 3
-bash: /usr/local/nagios/libexec/check_nrpe: cannot execute binary file

Check is SElinux is enabled, and if it is, disable it.
