Nagios check_raid Bug for non Dm users:

https://github.com/glensc/nagios-plugin-check_raid/issues/142

since an update, the query for DM causes an error. Workaround for md Raid users is:

-p mdstat:

define command {
 command_name    check_raid
 command_line    /usr/lib/nagios/plugins/check_raid $ARG1$
}

define service{
    use                  generic-service
    host_name            localhost
    service_description  Linux RAID
    check_command        check_raid!-p mdstat!
    normal_check_interval  120
    retry_check_interval 5
}
