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. 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.
•
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
and
Hostip
Source IP address of the log. If info-center loghost source is configured, this field
displays the IP address of the specified source interface. Otherwise, this field
displays the sysname.
This field exists only in logs in unicom format that are sent to the log host.
