The IT farm has 4 Brother DCP-7065DN printers, I wanted to monitor the status of the cartridges, and ran into problems:
  1. The plugin for Nagios check_snmp_printer is not suitable, it returns the wrong value, although it is perfect for monitoring the state of the drum.

  2. I could not find on the network what SNMP OID of the cartridge status for this printer.

I wrote to Brother support ... And unexpectedly for themselves they answered and gave me the OID for my printer. Opened my favorite VIM and wrote a bash script for Nagios. And now I share it check_snmp_brother.

We put this script in the folder with Nagios plugins, set the necessary rights, and set the flag for execution.

Configuring Nagios

define command{
command_name  check_snmp_brother
command_line  $USER1$/check_snmp_brother $ARG1$ $HOSTADDRESS$ $ARG2$ $ARG3$
}
define service{
        use                          default-service
        host_name                    PRINTER
        service_description          Toner Black
        check_command                check_snmp_brother!public!20!10
        }

The script works correctly for Brother DCP-7065DN model. If it works for other models, I will be glad if you let me know.
