recommended that this always be selected.
•EVENT. An informational message (e.g., subsystem initializing, subsystem terminating) about a
significant occurrence in the system that is usually not an error. It is recommended that this
always be selected.
•REQUEST. A message which reports the beginning and ending of processing of a client request in
a server. It is recommended that this type not be selected except for short periods as an aid to
isolating a problem.
•SECURITY. A message reporting security related events (e.g., authorization failures). It is
recommended that this always be selected.
•DEBUG. A lower-level error message. For troubleshooting, these messages are important record
types because they provide more detailed information about the root cause of an error. It is
recommended that this always be selected.
•TRACE. A message for tracing any type of entry/exit processing flows. It is recommended that
this type not be selected except for short periods as an aid to isolating a problem.
•STATUS. A message reporting the interim progress of a long-running task.
•ACCOUNTING. A message which logs accounting information.
It is recommended that at least the Alarm, Event, Security and Status record types be selected for
all servers while they are running normally. Core Servers and Movers should als o log Debug
messages, and additional record types for debugging purposes should be selected for servers
experiencing problems. If system performance is being degraded by excessive logging, first turn
off Trace, Debug and Request record types for all servers. Other record types can be turned off
as necessary. However, the HPSS administrator may lose useful debugging information when
problems occur.
To facilitate diagnosis of data transfer problems, it is recommended that Debug logging always
be turned on for all Movers.
Record Types for SSM. Record types that are to be sent to SSM for display. If a box is select ed for a
record type, that type will be sent to the SSM for display in the Alarms and Events window (Section
5.2.2.3: on page 151). The allowed types are a subset of the allowed Record Types to Log described
above:
•SSM ALARM
•SSM EVENT
•SSM STATUS
It is recommended that Alarm and Event record types be sent to SSM.

Configuration window for that server (Section 5.1.1.1: Log Policy on page 95), or from the Loggi ng
Policies window (Section 9.2.2: Logging Policies Window on page 296).
