check_xenvm.sh

the plugin works perfectly when used on local machine. In order to use it with check_by_ssh you need to do following modifications:

On the monitored host:
in /etc/sudoers add:

Defaults:nagios !requirettl
nagios ALL=(ALL) NOPASSWD: /check_xen *

edit the script:

in the line RUNNING=$(sudo /usr/sbin/xm list | awk '!/[DN]/ {print $1 }' | awk '$1=$1' OFS=", " RS= )
remove sudo:
RUNNING=$( /usr/sbin/xm list | awk '!/[DN]/ {print $1 }' | awk '$1=$1' OFS=", " RS= )

On the Nagios host:
add command:
define command{
command_name ssh_xen
command_line $USER1$/check_by_ssh -H $HOSTADDRESS$ -C 'sudo /check_xen -w $ARG1$ -c $ARG2$'
}
