On the same sort of ssh track... Is it possible to configure ssh or check_by_ssh to use a ssh tunnel ? I have a number of heavy loaded computers (executing climate models) where re-establishing ssh connections every 30 seconds is causing a load problem.
I guess the goal would be to have a check-plugin were it looks for a tunnel and then leaves the tunnel open after the check has finished. Is there a existing check which does something like this ??
