Description
Log
Indicates whether the system is currently recording events.
You can enable or disable
event logging.
By default, it is disabled.
Log level
Allows you to configure the event level and filter out unwanted events below this
level.
The events ranging from the highest critical level “Emergency” down to this
configured level will be recorded to the log buffer on the Router’s SDRAM.
When
the log buffer is full, the newest event will wrap up to the top of the log buffer and
overwrite the oldest event.
By default, the log level is “Debugging”, which is the
lowest critical level.
The log levels are defined as follows:
Emergency is the most serious event level, whereas Debugging is the least important.
For instance, if the log level is set to Debugging, all the events from the lowest
Debugging level to the most critical level Emergency level will be recorded.
If the log
level is set to Error, only Error and the level above will be logged.
Display Level
Allows you to select the logged events and displays on the View System Log window
for events of this level and above to the highest Emergency level.
Mode
Allows you to specify whether events should be stored in the local memory, be sent to
a remote syslog server, or to both simultaneously.
If remote mode is selected, the view system log will not be able to display events
saved in the remote syslog server.
When either Remote mode or Both mode is
configured, the WEB UI will prompt the you to enter the Server IP address and Server
UDP port.
3:
Click View System Log. The results are displayed as follows.
