454 CHAPTER 40: INFORMATION CENTER
To sum up, the major task of the information center is to output the three types of
information of the modules onto the ten channels in terms of the eight severity
levels and according to the user’s settings, and then redirect the system
information from the ten channels to the six output directions.
System Information
Format
System information has the following format:
<priority>timestamp sysname module/level/digest:content
n
■ The closing set of angel brackets < >, the space, the forward slash /, and the
colon are all required in the above format.
■ Before the <priority> may have %, "#, or * followed with a space, indicating
log, alarm, or debugging information respectively.
Below is an example of the format of log information to be output to a log host:
% <188>Dec 6 10:44:55:283 2006 3Com NTP/5/NTP_LOG:- 1 - NTP service enable
("-1-" indicates that the unit number of the device is 1.)
What follows is a detailed explanation of the fields involved:
Priority
The priority is calculated using the following formula: facility*8+severity-1, in
which
■ facility (the device name) defaults to local7 with the value being 23 (the value
of local6 is 22, that of local5 is 21, and so on).
■ severity (the information level) ranges from 1 to 8. Tab le 338 details the value
and meaning associated with each severity.
Note that there is no space between the priority and timestamp fields and the
priority field appears only when the information has been sent to the log host.
Timestamp
Timestamp records the time when system information is generated to allow users
to check and identify system events.
n
There is a space between the timestamp and sysname (host name) fields.
The time stamp has the following two formats.
■ Without the universal time coordinated (UTC) time zone, the time stamp is in
the format of "Mmm dd hh:mm:ss:ms yyyy".
