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.
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. It 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 information 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 10 and Table 11.
