ONFIGURATION
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 ten channels to the six output destinations.
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>, there may be a %, “#, or * followed with a space,
indicating log, alarm, or debugging information respectively.
■
This format is the standard format of system information. After the system
information is sent to the log host, the displayed format depends on the tools
you use to view the logs.
Below is an example of the format of log information to be output to a log host:
% <188>Sep 28 15:33:46:235 2005 MyDevice SHELL/5/LOGIN: Console login from aux0
What follows is a detailed explanation of the fields involved:
Priority
The priority is calculated using the following formula: facility*8+severity, in which
facility represents the logging facility name and can be configured when you set
the log host parameters. The facility ranges from local0 to local7 (16 to 23 in
decimal integers) and defaults to local7. The facility is mainly used to mark
different log sources on the log host, query and filter the logs of the
corresponding log source. Severity ranges from 0 to 7. Table 76 details the value
and meaning associated with each severity.
Note that there is no space between the priority and timestamp fields and that the
priority takes effect 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.
