Syslog messages
B
B.1
Structure of the Syslog messages
The Syslog server collects all log information of the devices and informs you about specific
events. The Syslog messages are received from the Syslog server over the configured UDP
port (default: 514) and sent according to RFC 5424 or RFC 5426.
Syslog messages log information during access to the device. Information can be status
information, such as the origin of the message or a time stamp. The Syslog protocol
prescribes a specified order and structure of the possible parameters. Syslog messages are
structured as follows in accordance with RFC 5424:
Table B- 1
Structure of the Syslog messages
Parameter
Explanation
HEADER
PRI
Within PRI, the priority of the Syslog message is coded into Severity (severity of the message)
and Facility (origin of the message).
VERSION
Version number of the Syslog specification.
TIMESTAMP
The device sends the time stamp in the format "2010-01-01T02:03:15.0003+02:00" as local time
including time zone and adjustment for daylight saving time/standard time, if necessary.
HOSTNAME
References the source computer with its name or IP address.
IPv4 address according to RFC1035: Bytes in decimal form: XXX.XXX.XXX.XXX
If there is no information, "-" is output.
APP-NAME
Device or application from which the message originates.
This parameter is not used by the device and "-" is always output.
PROCID
The process ID is used to clearly identify the individual processes, for example, during analysis
and troubleshooting.
This parameter is not used by the device and "-" is always output.
MSGID
ID for identification of the message.
This parameter is not used by the device and "-" is always output.
STRUCTURED-DATA
timeQuality
The structured data element "timeQuality" provides information on the system time.
The "tzKnown" parameter specifies whether the sender knows its time zone (value "1" = known;
value "0" = unknown).
The "isSynced" parameter specifies whether the sender is synchronized with a reliable external
time source, e.g. via NTP (value "1" = synchronized; value "0" = not synchronized).
sysUpTime
The "sysUpTime" parameter is metainformation about the message.
It specifies the time (in hundredths of a second) since the last reinitialization of the network man-
agement part of the system.
MSG
MESSAGE
Message as ASCII string (English)
