Just install the plugins on the remote machine, and use check_by_ssh.

NRPE is another option, but I don't know that its security model is a
strict as you want.

Keep in mind that check_by_ssh is not built for performamnce.

Also, for the simplest cases, 'ssh <command to execute> does the same as
check_by_ssh, with one less layer of overhead.

But to check a number of services on one invocation, check_by_ssh can be
used to drop multiple services into the collector for a passive check
that uses only one SSH connection per checked host.
