8.2 System Log
This function allows a system log to be kept and viewed upon request.
Follow the steps below to configure, enable, and view the system log.
STEP 1: Click Configure System Log, as shown below (circled in Red).
STEP 2: Select desired options and click Apply/Save.
Consult the table below for detailed descriptions of each system log option.
Option Description
Log Indicates whether the system is currently recording events. The user
can enable or disable event logging. By default, it is disabled. To
enable it, select the Enable radio button and then click Apply/Save.
119
Option Description
Log
Level
Allows you to configure the event level and filter out unwanted events
below this level. The events ranging from the high est critical level
“Emergency” down to this configured level will be recorded to the log
buffer on the VR-3033 SDRAM. When the log buffer is full, the newer
event will wrap up to the top of the log buffer and overwrite the old event.
By default, the log level is “Debugging” , which is the lowest critical level.
The log levels are defined as follows:
• Emergency = system is unusable
• Alert = action must be taken immediately
• Critical = critical conditions
• Error = Error conditions
• Warning = normal but significant condition
• Notice= normal but insignificant condition
• Informational= provides information for reference
• Debugging = debug-level messages
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 the user 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, or be sent to a remote system log server, or both
simultaneously. If remote mode is selected, view system log will not be
able to display events saved in the remote system log server.
When either Remote mode or Both mode is configured, the WEB UI will
prompt the user to enter the Server IP address and Server UDP port.
STEP 3: Click View System Log. The results are displayed as follows.
