The audit log file is a text file in the syslog format. The audit log file has two types of formats: RFC3164-compliant and RFC5424-compliant. Select either one of them when setting for transferring audit log files to syslog servers or exporting audit log files.
An audit log file consists of the following fields: Audit log header, Audit log information (Basic Information), and Audit log information (Detailed Information), whose formats are respectively described in the following topics.
If an audit log file is to be transferred to the syslog server, syslog header information is included before the audit log header, which is described in this chapter. For details about the format of audit log files when audit log files are transferred to the syslog server, see Format of audit log files when audit log files are transferred to the syslog server.
