message "NRPE:unable to read output"

The group permissions for the libexec folder by default, has the set user or group ID on execution set and your folder doesn't have that.
Can you login to the AIX server as root and run the following?

Code: Select all

chmod g+rws /usr/local/nagios/libexec/

Then test to see if this works for you.

Thanks

Can you run successfully the following command on the Nagios XI box from the command line?

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H 10.147.109.30

You may need to add the "check_disk" plugin to the sudoers, i.e.

Code: Select all

nagios   ALL = NOPASSWD:/usr/local/nagios/libexec/check_disk *

Unfortunately we don't have an AIX system in house to test this.

FYI, we cannot see what the permissions are on "check_disk" from the screenshot that you provided.

You may need to add the "check_disk" plugin to the sudoers, i.e.

Code: Select all

nagios   ALL = NOPASSWD:/usr/local/nagios/libexec/check_disk *

Can you make this change on the AIX system? The permissions are root:root which may be why you are seeing this issue.

Hi Team,

we inserted the below provided line into the sudousers file, but still we are getting the same error:

nagios   ALL = NOPASSWD:/usr/local/nagios/libexec/check_disk *

Please suggest if any further action to be taken.

Just to inform that for any other server, we are not adding this line into the sudousers file but we are able to monitor it successfully.
can you please confirm on this query as well.

What is the name and IP address of the AIX server?
Does the nagios user have access to the /home folder on the AIX server?
