572 Traps
Understanding Trap Severity
Traps often contain information about values recorded by probes or sensors. Probes and sensors monitor
critical components for values such as amperage, voltage, and temperature. When an event occurs on
your system, the Server Administrator sends information about one of the following event types to the
system management console:
• Information/Informational — An event that describes the successful operation of a unit, such as a
power supply turning on or a sensor reading returning to normal.
•
Warning — An event that is not necessarily significant, but may indicate a possible future problem,
such as crossing a warning threshold.
•
Critical/Error — A significant event that indicates actual or imminent loss of data or loss of function,
such as crossing a failure threshold or a hardware failure.
Instrumentation Traps
This section describes the traps that are generated by the Instrumentation service of the Server
Administrator. All of the traps documented in this section belong to the MIB enterprise identified by
OID 1.3.6.1.4.1.674.10892.1 and are sent with all of the trap variables documented in the section, "Trap
Variables." The trap variables are sent in the order in which they are listed. The messages in the
Description fields below show the format of the message that is sent in the alertMessage varbind. If a
message in a Description field has multiple lines, the message contains newline (0Ah) characters that are
part of the value in the alertMessage varbind.
