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
values16 through 23. The facility name can be configured using 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
for more information about severity
levels.
