• Analysis: Both of the export approaches are configured.

server.
Session logging
NOTE:
The LB module supports configuring session logging only on the web interface.
Session logging overview
Session logging records users’ access information, IP address translation information, and traffic
information, and can output the records in a specific format to a log host, allowing administrators to
perform security auditing.
Session logging records an entry for a session if it reaches the specified threshold. Session logging
supports two categories of thresholds:
• Time threshold—When the lifetime of a session reaches this threshold, a log entry is output for the
session.
• Traffic threshold—The traffic threshold can be in units of the number of bytes or the number of
packets. When the traffic of a session reaches the specified number of bytes or packets, a log entry
is output for the session.
NOTE:
Session logs are output in the format of user logs. To view session logs, you also need to configure user
logging.
Table 9 Session logging configuration task list
Task Remarks
Configuring a session logging
policy
Required
Configure a session logging policy, specifying the source zone and
destination zone of the sessions and the ACL for filtering log entries.
By default, no session logging policy exists.
Setting session logging
thresholds
Required
Configure the time threshold or/and traffic threshold for session logging.
By default, both the time threshold and traffic threshold are 0, meaning that
no session logging entries should be output.
IMPORTANT:
If both the time threshold and traffic threshold are configured, a log entry is
output for the session when it reaches whichever threshold and the statistics of
the session will be cleared.
