I tried but didnt work ...i made the ssh key exchange to remote servers ... when i call them i get unkown .. it looks like a permission issue

[fsodah]

I used the following document you made it available for me https://assets.nagios.com/downloads/nag ... ng_SSH.pdf Your feedback appreciated.

Why i keep getting ";Current Users;UNKNOWN;HARD;5;Remote command execution failed: bash: /usr/local/nagios/libexec/check_users: No such file or directory"

Do I need to install any thing on the remote host, since our policy not to install any extra packages, if its a must ... what would be the best to apply the plugins on remote host using redhat7.x

From nagios i can run the command remotely, it gave me the right response

Code: Select all

[nagios@nagios ~]$ /usr/local/nagios/libexec/check_by_ssh -H 10.1.x.x -C uptime
 20:53:36 up 86 days,  3:28,  1 user,  load average: 0.00, 0.00, 0.00

Yes, the check_by_ssh command runs a program or command on the remote system. So if your check_by_ssh command calls /usr/local/nagios/libexec/check_users, then that plugin will need to be installed on the remote system. You could also use an agent like NCPA, but if you have a policy against extra packages that could be a problem.

The standard Nagios plugins have to be compiled. I don't know how that works with your policy. But if that's a preferred method, you can download the standard plugins here,
https://www.nagios.org/downloads/nagios-plugins/

Once the plugins are compiled and installed on the remote system, then you can use the check_by_ssh command to call /usr/local/nagios/libexec/check_cpu, and other plugins.

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Try running yum clean all and then installing the NRPE agent.

[fsodah]

with NRPE didnt work I made up my mind and installed NCPA ... it works

Excellent! Does this put you in a good spot to start monitoring your environment? Should I close this thread?
