About Logging

 

 

 

Table 19-3

Remote Syslog Message Header Format

 

 

 

 

 

 

 

Field

 

Description

 

 

 

 

 

 

 

pri_num

 

Priority value of the message; a combination of the facility value and the

 

 

 

 

severity value of the message. Priority value = (facility value* 8) + severity

 

 

 

 

value. The facility code valid options are:

 

 

 

 

LOCAL0 (Code = 16)

 

 

 

 

LOCAL1 (Code = 17)

 

 

 

 

LOCAL2 (Code = 18)

 

 

 

 

LOCAL3 (Code = 19)

 

 

 

 

LOCAL4 (Code = 20)

 

 

 

 

LOCAL5 (Code = 21)

 

 

 

 

LOCAL6 (Code = 22; default)

 

 

 

 

LOCAL7 (Code = 23)

 

 

 

 

Severity value—See Table 19-1for severity values.

 

 

 

 

 

 

 

time

 

Date of the message generation, according to the local clock of the

 

 

 

 

originating ACS, in the format YYYY Mmm DD hh:mm:ss. Possible values

 

 

 

 

are:

 

 

 

 

YYYY = Numeric representation of the year.

 

 

 

 

Mmm = Representation of the month—Jan, Feb, Mar, Apr, May, Jun, Jul,

 

 

 

 

Aug, Sep, Oct, Nov, Dec.

 

 

 

 

DD = Numeric representation of the day of the month. For single-digit

 

 

 

 

days (1 to 9), a space precedes the number.

 

 

 

 

hh = The hour of the day—00 to 23.

 

 

 

 

mm = The minute of the hour—00 to 59.

 

 

 

 

ss = The second of the minute—00 to 59.

 

 

 

 

Some device send messages that specify a time zone in the format -/+hhmm,

 

 

 

 

where - and + identifies the directional offset from the ACS server’s time

 

 

 

 

zone, hh is the number of offset hours, and mm is the number of minutes of

 

 

 

 

the offset hour.

 

 

 

 

For example, +02:00 indicates that the message occurred at the time indicated

 

 

 

 

by the time stamp, and on an ACS node that is two hours ahead of the ACS

 

 

 

 

server’s time zone.

 

 

 

 

 

 

xx:xx:xx:xx/host_name

IP address of the originating ACS, or the hostname.

 

 

 

 

 

 

 

cat_name

 

Logging category name preceded by the CSCOacs string.

 

 

 

 

 

 

 

msg_id

 

Unique message ID; 1 to 4294967295. The message ID increases by 1 with

 

 

 

 

each new message. Message IDs restart at 1 each time the application is

 

 

 

 

restarted.

 

 

 

 

 

 

 

total_seg

 

Total number of segments in a log message. Long messages are divided into

 

 

 

 

more than one segment.

 

 

 

 

 

 

 

seg_num

 

Segment sequence number within a message. Use this number to determine

 

 

 

 

what segment of the message you are viewing.
