Traps 567
Traps
The Server Administrator generates events that result in Simple Network Management Protocol (SNMP)
traps or operating system event logs. Remote Access Controller (RAC) and Baseboard Management
Controller (BMC) also can generate SNMP traps in response to hardware events. This section
describes the traps, also known as alerts, generated by the Server Administrator, RAC, and BMC.
The Server Administrator generates events in response to changes in the status of sensors and other
monitored parameters. When an event with predefined characteristics occurs on your system, the
SNMP subagent sends information about the event, along with trap variables, to the
management console.
Each status change event generates a unique identifier called the trap ID and a trap description that
describes the event. The trap ID and message uniquely describe the severity and cause of the event,
and provide other relevant information such as the location of the event and the monitored item’s
previous state.
"Instrumentation Traps," found later in this section, lists all Server Administrator Instrumentation
trap IDs in numerical order and includes each trap ID’s corresponding description, severity level, and
cause. Description text in brackets (for example, <
State >) describes the event-specific information
provided by Server Administrator.
"RAC Traps," found later in this section, lists RAC trap IDs in numerical order and includes each
trap ID’s corresponding description, severity level, and cause.
"BMC Traps," found later in this section, lists BMC trap IDs and includes each trap ID’s
corresponding description and severity level.
Trap Variables
This section describes the variables that are sent to the management console to provide additional
information about a trap or alert generated by some event on your system. The trap variables
presented here apply to all Instrumentation and RAC traps. Trap variables are sent in the order listed
and are reserved for use only in traps. When a varbind is created for a trap variable, a zero is
appended to the object ID (OID) to create the OID for the varbind.
