Hello, thank you for your time, the answer you give me does not help me since in those examples a port 2375 is used but as I said I need to make the query for an available ssh port 22 but I cannot perform a correct execution

I am testing with check_by_ssh where I program it like this

Create in Configuration > Commands > Checks a check called Docker_Check_SSH:

$USER1$/check_by_ssh -l $ARG3$ -i $ARG1$ -H $HOSTADDRESS$ -C $ARG2$ -E

ARG3 : user
ARG1 : rsa key path
ARG2 : command

where i use the check_docker.sh plugin downloaded from nagios

The final command would be something like this:
/bin/sh -c '/usr/lib64/nagios/plugins/check_by_ssh -l user -i /var/spool/useer/.ssh/id_rsa -H [remote-host-ip] -C "/home/user/ check_docker.sh -n python -s" -E'

and it gives me an answer:

UNKNOWN - check_by_ssh: Remote command '/home/ansible/user/check_docker.sh -n python -s' returned status 255
