696 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" on page 690. 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.
Voltage sensor value
(in Volts):
<Reading>
Specifies the voltage sensor value in volts, for
example:
Voltage sensor value: 1.693
