Monitoring with SSH without installing plugins to client

[judanssi]

On NCA Prep guide is mentioned, that: "The final reason you may consider SSH to the checking on the remote server is that you may not be able to install
applications or compile applications on the remote server."

Anyway check_by_ssh does require the plugins installed on remote server. ("In order to use SSH you need to use the check_by_ssh plugin which will enable you to perform local checks on the remote machine.")

Is there any solution to monitor clients with SSH without installing plugins to client? I couldnt find any documentation of this.

This is in reference to the fact that check_by_ssh does not require a full agent install (nrpe, etc).

The check_by_ssh plugin still requires the plugin scripts to reside on the remote system, but does not require an agent (daemonized application / service) to be installed. If you want to monitor without copying anything to the remote system, you are stuck monitoring externally accessible ports. You could also monitor through snmp, but that would require a package install on the remote host.
