Nagios Plugin Bug

# check command
define command {
    command_name    check_remote_disk
    command_line    $USER1$/check_by_ssh -p $ARG1$ -l nagios -i /usr/local/rep/nagios/auth/keys/nagios-utility-key -H $HOSTADDRESS$ -C 'check_disk -w $ARG2$ -c $ARG3$ -p $ARG4$'
}

# service definition
# contact groups are defined, I just have not included that here
define service {
    service_description             Partition Root
    check_command                   check_remote_disk!22!20%!10%!/
}

# status information in nagios from the above
DISK CRITICAL - free space: / 319 MB (3% inode=67%):

# local command being run on the server
$ /usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /
# return status is 2, status output follows
DISK CRITICAL - free space: / 318 MB (3% inode=67%);| /=9248MB;8063;9071;0;10079

# so this is clearly an issue with check_by_ssh

# further evidence
# 'check_remote_dummy' command definition
define command {
    command_name    check_remote_dummy
    command_line    $USER1$/check_by_ssh -p $ARG1$ -l nagios -i /usr/local/rep/nagios/auth/keys/nagios-utility-key -H $HOSTADDRESS$ -C 'check_dummy $ARG2$ $ARG3$'
}

# Define a service to always fail, this should help diagnose the check_by_ssh bug
define service {
    use                             fam-service
    service_description             Always Critical Test

# the above always shows up as ok even though it should only be in a critical state
