EMS Trap Subagent

Configuration

Before using the EMS Trap Subagent, you need to create an event filter and might
need to configure trap connections. This subsection describes these operations.

Event Filter

The EMS Trap Subagent uses an event filter known as a routing distributor filter to
determine where to route trap messages. The filter contains a destination statement
that identifies the SNMP agent as the routing destination. The filter can also contain
specifications for selecting events to convert into traps. Refer to the EMS Manual for
information on how to encode and install routing distributor filters.
Example 9-2 shows the source code for an event filter that selects and passes all
events generated by HP subsystems. This example filter also provides, as part of the
routing destination statement, a DEFINE name (=_SNMP_AGENT) to identify the
SNMP agent. The DEFINE name, which circumvents hard coding of an agent process
name, is resolved at run time, as in
The lines shown in bold type contain the event-selection specifications.
Note. See the Operator Messages Manual for the names, numbers, and descriptions of
supported subsystems.
