D Monitoring Printers
Implementing Remote Management Software (RMS)
Remote printer management includes the following tasks:
• Monitoring the status of network printers
• Responding to alarms
• Gathering statistics on printer operations
The three elements of network printer monitoring and management are:
• Agent/manager model
• MIB, the management information database
• SNMP, the protocol used to get management information
Agent/Manager Model
The elements of a monitoring system, MIB and SNMP, are implemented in an
agent/manager model:
• The manager is a console, workstation, or server on working hubs or
routers which has a global knowledge of NIC and printers. OpenView is a
management console.
• Agents are utilities that reside on devices, such as a NIC, that respond
through SNMP to management requests for information. The information
is stored in a MIB (Management Information Base).
MIB
A MIB is a Management Information Base that contains information a device
makes available to SNMP. The MIB describes information about actual
objects to be managed, controlled, and viewed. There are many different
MIBs defined.
Standards of Network Printer MIBs
The Printer MIB contained in the NIC is based on the following standards:
• System and Interfaces Group MIB (RFC 1213 of March 1991)
• Host Resource MIB (RFC 1514 of September 1993)
• Printer MIB (RFC 1759 of March 1995)
