Syslog Messages
D
D.1 Structure of the Syslog Messages
The Syslog server collects log information of the devices and informs you about specific
events. The Syslog messages are transmitted via the set UDP port (standard 514) according
to RFC 5424.
Syslog messages log information when the device is accessed. Information can be status
information such as the origin of the message or a time stamp. The Syslog protocol
prescribes a fixed sequence and structure of the possible parameters.
The Syslog message consists of the following parameters:
Parameter Explanation
HEADER
PRI
PRI contains the coded priority of the Syslog message, broken down 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 the local
time including the time zone and correction for daylight saving / standard time if needed.
HOSTNAME The station name configured in the "System" tab for the RTU.
APP-NAME Device or application from which the message originates.
"-" is output if information is missing.
PROCID The process ID serves to clearly identify the individual processes, for example during analysis
and troubleshooting.
"-" is output if information is missing.
MSGID ID to identify the message. "-" is output if information is missing.
STRUCTURED-DATA
timeQuality
The structured data element "timeQuality" provides information on system time. Example:
[timeQuality tzKnown="0" isSynced="0"]
The "tzKnown" parameter indicates whether the sender knows its time zone (value "1" = known;
value "0" = unknown).
The "isSynced" parameter indicates whether the sender is synchronized with a reliable external
time source, e.g. via NTP (value "1" = synchronized; value "0" = not synchronized).
MSG
MESSAGE
Message as ASCII string (English)
Note
Additional information
You can read more detailed information on the structure of the Syslog messages and on the
meaning of the parameters in RFC 5424.
