|Generic Printer: Input Unit State|
|Distribution||official part of Check_MK|
The printer has to support the generic PRINTER-MIB.
By default the check outputs
CRITICAL when either the printer reports 0%
units remaining or reports a critical error state. A
WARNING state is raised when a non-critical error is provided.
According the PRINTER-MIB it's possible that a printer couldn't determine how much is remaining in a supply, so the printer says "at least one remaining".
Name of the printer (if set) otherwise the description, type or index of the printer
One service is created for each unit with a unique name.
