Information Center Configuration Chapter 1 Overview

1-2

logbuffer Log buffer

logfile <1-4> Log file

The Settings for the output directions are independent of each other, but the

information center needs to be opened before the settings take effect.

1.4 Source information format

The format of the source information is as follows

：

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

The angle brackets (<>), spaces, slashes (/), and colon (:) are required in the above

format when configuring the log prefix; where angle brackets are valid only when the

output direction is the log host.

An example of the log format to be output to the log host is shown below:

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

Another example of the log format without prefix is shown below:

Console login from con0

Each field is described in detail below:

1) Priority

The priority is calculated as follows

facility*8+severity-1。

Facility can be local0 ~ local7, default is local7. The value is 16-23

Severity ranges from 1 to 8. For more information about severity, refer to Table 1-1.

There is no character between the priority and the timestamp. The priority is valid

only when the information is sent to the log host.

The origin of facililty is worth mentioning. Facility is a unique attribute when

information is output to the log host, and has no meaning for other output directions. Its

value local0 ~ local7 comes from the log type which the early syslog protocol defined for

the UNIX log host. All types are as follows:
