Table 13 describes the fields in a log message.
Table 13 Log field description
Field Description
Prefix (information type)
A log to a destination other than the log host has an identifier in front of the
timestamp:
• An identifier of percent sign (%) indicates a log with a level equal to or
higher than informational.
• An identifier of asterisk (*) indicates a debug log or a trace log.
• An identifier of caret (^) indicates a diagnostic log.
PRI (priority)
A log destined to the log host has a priority identifier in front of the timestamp.
The priority is calculated by using this formula: facility*8+level, where:
• facility is the facility name. Facility names local0 through local7
correspond to values 16 through 23. The facility name can be configured
with the info-center loghost command. It is used to identify log sources on
the log host, and to query and filter the logs from specific log sources.
• level ranges from 0 to 7. See Table 6 for more informati
on about severity
levels.
Timestamp
Records the time when the log was generated.
Logs sent to the log host and those sent to the other destinations have different
timestamp precisions, and their timestamp formats are configured with different
commands. For more information, see Table 14 and Table 15.

This field exists only in logs in unicom format that are sent to the log host.
