4.2.4 Introduction to Syslog
The syslog function is a sub-function provided by the information center. This section
describes the format of the log sent to log hosts. Port 514 is used for the output to log
hosts.
The format of log information is specified in the BSD syslog protocol (RFC 3164) with
extension to the header, shown as follows:
<priority> timestamp sysname module/level/digest:content
Where, “< >”, space, “/” and “:” are valid and mandatory.
For example:
<189> Jun 7 05:22:03 2003 XE IFNET/6/UPDOWN:Line protocol on interface
Ethernet0/0, changed state to UP
The following is the description on fields in the log information.
I. Severity
The severity level is computed using this formula: facility x 8 + severity - 1. For
Comware, facility defaults to 23, severity defaults to a value in the range 1 to 8, as
shown in Table 4-8 .
No characters are allowed between severity and timestamp.
II. Timestamp
The time field of the log information sent to a log host is expressed in date notation.
The timestamp is in the format of Mmm dd hh:mm:ss yyyy.
Mmm is the abbreviated form of the month: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep,
Oct, Nov, or Dec.
dd is the abbreviated form of the day. If it is less than 10, one space must be inserted
before the number, for example, “ 7”.
“hh:mm:ss is the time of day, where hh is an hour value in 24-hour notation (00 to 23),
and mm and ss are minute and second values from 00 to 59.
“yyyy” is the year.
The timestamp and host names are separated by a space.
III. Host name
The host is named using its host name, which is XE by default.
You can use the sysname command to modify it.
The host name and the module name are separated by a space.
