Chapter 1 Information Center Configuration

Acting as the system information hub, information center classifies and manages

system information. Together with the debugging functionality, information center offers

a powerful support to the network administrators and developers in monitoring network

performance and diagnosing network problems.

System information has the following format:

<priority>timestamp sysname module/level/digest:content

Note:

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 debug information respectively.

Below is the format of log information to be output to a log host:

% <188>Sep 28 15:33:46:235 2005 Sysname SHELL/5/LOGIN: Console login from con0

What follows is a detailed explanation of the fields involved:

I. Priority

The priority is calculated using the following formula: facility*8+severity-1, in which

facility is local7 by default and the range of severity is 0 to 7. Table 1-2 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 only takes effect when the information has been sent to the log host.

II. Timestamp

Timestamp records the time when system information is generated to allow users

check and identify system events.

Note that there is a space between the timestamp and sysname (host name) fields.
