Hi @Johnsmit

This type error can be caused by an incorrect plugin path. Please verify that the plugin path on the remote machine matches the path in the config file, nrpe.cfg.

The default path for plugins is:
/usr/local/nagios/libexec/

Then compare with the path for the command directive in nrpe.cfg:
command[check_users]=/usr/local/nagios/libexec/check_users $ARG1$

We have a knowledgebase article on troubleshooting this type of error at:
https://support.nagios.com/kb/article/n ... t-620.html

Let me know this resolves the issue.
