Just write a local plugin around the sysadmin’s SSH command. 5. 5 A script that calls load_checker and parrots its output and exit code. sh"' #get the exit code CODE=$? 5 doesn’t have any conditional logic. Its only job is to execute the remote script, and parrot back its output and exit code to the local terminal. But because it does exit with the proper code and passes back a single line of text, it’s good enough for Nagios. It’s a plugin that calls another plugin via Secure Shell (SSH), but Nagios doesn’t know about this, or care, as long as an exit code and some text are returned.

Hosts and Services As mentioned earlier, Nagios makes few assumptions about what and how you want to monitor. It allows you to define everything. Definitions are the bread and butter of how Nagios works. Every element Nagios operates with is user-defined. For example, Nagios knows that in the event a plugin returns a critical state, it should send a notification, but Nagios doesn’t know what it means to send one. You define the literal command syntax Nagios uses to notify contacts, and you may do this on a contact-by-contact basis, a service-by-service basis, or both.

An interesting thing about executing scripts remotely with SSH is that not only does SSH capture and pass back the output from the remote script, but also its exit code.
