In its subagent role, the Trap Multiplexer provides a MIB that SNMP managers can
access by routing requests through a SNMP agent that resides either on the same host
as the Trap Multiplexer or on a remote node. The Trap Multiplexer’s MIB, which resides
in the subtree registered to Tandem, is organized into two groups, identified by a check
mark in the following list:
iso (1)
identified-organization (3)
dod (6)
internet (1)
private (4)
enterprises (1)
tandem (169)
nonstopsystems (3)
ztmx (185)
ztmxPDUStatistics (1) √
ztmxProcess (2) √
The ztmxPDUStatistics group contains counts of the UDP and SNMP PDUs received
by the Trap Multiplexer. The ztmxProcess group objects let you review and change
configuration attributes of the Trap Multiplexer. Details about each of the objects in
these groups can be found in ztmxPDUStatistics Group on page 12-12 and
ztmxProcess Group on page 12-16.

The EMS Manual describes the Event Management Service (EMS). EMS is a
collection of processes, tools, and interfaces that provide event-message collection
and distribution in the Distributed Systems Management environment. The Trap
Multiplexer converts SNMP traps into EMS event messages, by mapping elements
of the trap PDU into EMS tokens.

The SPI Programming Manual describes the standard Subsystem Programmatic
Interface (SPI) tokens that appear in EMS events generated by the Trap
Multiplexer. It also describes how to use SPI procedures to programmatically
retrieve information from generated events. The sample application described at
the end of this section illustrates how to embed SPI procedure calls in a C
language program in order to retrieve information from events created from traps
received by the Trap Multiplexer.
