Domino® SNMP Agent architecture

Domino® SNMP Agent services are provided by two types of programs.

  • LNSNMP -- The Notes® SNMP agent. As an independent application, LNSNMP is insulated from most Domino® server malfunctions and, by itself, adds negligible overhead to the server.
  • Two Domino® server add-ins -- the QuerySet Handler and the Event Interceptor.

    The QuerySet Handler and the Event Interceptor depend on the Domino® server; if the server fails for any reason, these programs fail as well.

The following components comprise the Domino® SNMP Agent architecture:

  • A platform-specific master SNMP Agent -- An independent, non-IBM agent usually supplied with the operating system platform that provides SNMP services for the machine. This SNMP Agent transports the SNMP traps and Get/Set responses across the network to the management station.
  • The Domino® SNMP Agent consisting of:
    • LNSNMP -- Which receives trap notifications from the Event Interceptor and then forwards them to the management station using the platform-specific SNMP Agent. LNSNMP also handles requests for Domino-related information from the management station by passing the request to the QuerySet Handler and responding back to the management station.
    • QuerySet Handler -- Which queries server statistics information, sets the value of configurable Domino-based parameters, and returns Domino® statistics information to LNSNMP, which then forwards the information to the management station using the platform-specific master SNMP Agent.
    • Event Interceptor -- Which responds to the SNMP Trap notification for Domino® Event Handlers by instructing LNSNMP to issue a trap.
  • The Domino® MIB -- A standard Management Information Base (MIB) file for Domino® servers that can be compiled and used by a network management program such as NetView® or OpenView.

For additional information, refer to your operating system's or network management tool's documentation (such as NetView® or OpenView).
