Ericsson W21 - Manual (Page 60)

Configuration and Management
The system logging information is written to 3 files in the system and these
files are rotated in a circular fashion. The files are not saved to flash
memory and will be lost when rebooting the system or when power is
disconnected.
To view only a selection of the log events in the list, select a filter level from
the “Display” list. Available log levels are “Alarms only” and “All”. The
“Alarms only” log level corresponds to the Alarm indicator on the Ericsson
W21 unit and the information in the “ALARMS” section on the Overview
page.
Click Refresh to update the list with new information. The most recent logs
are listed at the bottom of the list.
2.10.1 Persistent Logging
If persistent logging is enabled, the log files are written to flash memory in
two alternating files meaning they will remain after a system restart or
power failure.
Note: Persistent logging should only be used for debugging purposes
since it consumes flash memory.
To enable this feature, select the “Persistent logging” check box on the
Event Log page and click
Apply to save the setting.
