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.

• A platform-specific master SNMP Agent -- An independent 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.
