check_by_ssh issue

[Nasri, Mahan]

Hi.


I use Nagios to monitor our remote setups (linux), servers, switches, etc. I'm having issues using the check_by_ssh command to check the remote setups' disk usage. Do i have to install the nagios plugin on each setup to execute the check_disk command on the remote host? Or is there another way?


This is the command_line i use:

/usr/local/nagios/libexec/check_by_ssh -H '$HOSTADDRESS$' -C "df -h /"


It works but i can't set any warnings (it will always indicate OK even if memory is full):

Thank you
