Logging
The storage system maintains the following types of logs for tracking events that
occur on the system. See Table 8 on page 30.
Table 8 Logs
Log type Description
System log Information displayed in Unisphere to notify users about storage system user-
actionable events. These records are localized according to the default language
setting specified for the system. Note that "user-actionable events" includes
audit events. However, not all logged events show up in the GUI. Those audit log
entries that don't don't meet a certain severity threshold are logged by the
system but don't appear in the GUI.
System
alert
Information used by the Service personnel to diagnose or monitor the storage
system status or behavior. These records are recorded in English only.
Viewing and managing logs
The following logging features are available for storage systems. See Table 9 on page
30.

Logging features
Feature Description
Log roll-over When the storage system log system accumulates two million log
entries, it purges the oldest 500K entries (as determined by log
record time) to return to 1.5 million log entries. You can archive log
entries by enabling remote logging so that log entries are uploaded
to a remote network node where they can be archived or backed
up. The Logging on page 30 section provides more information.
Logging levels Logging levels are not configurable for the storage system. Log
levels can only be configured for exported log files as described in
the Logging on page 30 section.

ways:

External log management You can archive log entries by enabling remote logging so that log
entries are uploaded to a remote network node where they can be
archived or backed up. There, you can use tools such as syslog to
filter and analyze log results. The Logging on page 30 section
provides more information.
