In the first screenshot, is that being run as the Nagios user? Or as root? The portion where we can see what user it is is cropped out.

[RIDS_I2MP]

Nagios user is give sudo root permissions. So the commands are executed as root user.

sudo su - root

Above mentioned is the command executed before other commands shown in the snapshot.

Hi Team,

Please let us know if any further input on this issue. As stated earlier in my response, we ran the command using Nagios user but Nagios user is having the root access.

Can you run the same command as a nagios user? Run the following commands on the remote machine and show the output?

Code: Select all

su nagios
/usr/local/nagios/libexec/check_disk -w 15% -c 10% -p  /home

This might have to do with permissions on the client machine.

On the client machine, can you run the following and post the output?

Code: Select all

ls -l /usr/local/nagios/libexec/

Can you post the output of this command as well?

Hi Team,

Please find the output of the commands in the attached snapshot.

It seems like nagios user doesn't have sufficient permissions. Can you log in as root on the remote machine, run the following commands and show the output?

Code: Select all

ls -lad /usr/local/nagios
ls -lad /usr/local/nagios/libexec
ls -la /usr/local/nagios/libexec/check_disk
