Log Message Format Description

Format of Log Message

The SYSLOG protocol uses UDP port 514 to transmit log messages. Any UDP packet on port 514 is considered a log message. The output format of a log message is shown in Figure 3-1.

Remarks

<Int_16>

Leading character.

This character is added to the information to be sent to the syslog server, not the information saved on a local device.

TimeStamp

Time to send logs.

Five timestamp formats are available:

  • boot: indicates that the timestamp is expressed in the format of relative time, a period of time since system start. The format is xxxxxx.yyyyyy. xxxxxx is the higher order 32 bits of the milliseconds elapsed since the start of the system; yyyyyy is the lower order 32 bits of the milliseconds elapsed since the start of the system.

  • date: indicates the current date and time. It is expressed in mm dd yyyy hh:mm:ss format.

  • short-date: indicates the short date. This timestamp differs from date is that the year is not displayed.

  • format-date: indicates that the timestamp is expressed in YYYY-MM-DD hh:mm:ss format.

  • none: indicates that no timestamp is contained in information.

Logs use the date format.

TimeZone

Local zone.

 Indicates local time zone information. This information is consistent with the Time Zone field of the display clock command output.

HostName

It is the source interface address for sending messages to the log host. The IPv4 address is empty, if the source interface is not configured.

IPv4 address and HostName are separated by a space.

Information type.

The information types are as follows:

  • l: log.

  • S: security log.

DDD

Log sequence number.

By default, the information center can output logs to the console, log buffer, SNMP agent, and log file. In the logbuffer, the value depends on the log buffer size. For example, the log buffer can store a maximum of 100 logs. The log sequence number ranges from 0 to 99.
