System information

9.4.5 System Log
The W3x terminals include a system log accessible both from the CLI and
WUI as a text file.
The system logging information is written to 5 files which are rotated in a
circular fashion. The files are limited to 200Kbytes each, which equals a
maximum of 1 MB total logging information. The files are not saved to flash
and will be lost when rebooting or when power is disconnected.
When persistent logging is enabled, the log files are written to flash
memory in two files alternately.
The syslog events can be saved to a local file or forwarded to a remote
syslog server.
Different levels of logging can be set depending on how much information
is desired.
Message types are specific to the logged information:
• Emergency, alert, critical and error messages report important
operation errors (e.g. a task crashed).
• Warning, notice and inform messages report important operation
information (e.g. system attack).
• Debug messages report operation details.
9.4.5.1 BSD Syslog Remote Logging
The W3x terminals are able to distribute the system log to a remote host
using the BSD Syslog message format on UDP.
In order to identify specific devices in a network, the product serial number
is also retrieved and sent as a parameter when the syslogd daemon is
initialized for remote logging.
9.4.5.2 Syslog Heartbeat
A regular heartbeat message can be sent to the syslog with a configurable
interval. The heartbeat messages will be classified as an alarm to simplify
the forwarding of this message to a remote syslog.
9.4.6 Fault Management
If an error condition occurs, the Alarm LED on the unit is lit (red) and the
corresponding cause is displayed in the WUI (on the Overview page). An
event message with severity level “Error” is also generated in the syslog.
Events that generate an alarm are such that make it impossible to send or
receive data, e.g. SIM card missing.
9.5 Interface Status and Statistics
The following subsections describe the status/statistics information that can
be displayed from the CLI and the WUI.
