■ System Logs Sends error messages to a logging process
■ Remote Logs Configures the logging of messages to a remote logging process

4.2.8.1 System Log Configuration
The system can be configured to send debug and error messages to a logging process. This logging process controls the type
of error messages that are stored in switch memory or sent to a remote syslog server.
The system allows you to enable or disable event logging, and specify which levels are logged to RAM or flash memory.
Severe error messages that are logged to flash memory are permanently stored in the switch to assist in troubleshooting
network problems. Up to 4096 log entries can be stored in the flash memory, with the oldest entries being overwritten first when
the available log memory (256 kilobytes) has been exceeded.
The System Logs page allows you to configure and limit system messages that are logged to flash or RAM memory. The default
is for event levels 0 to 3 to be logged to flash and levels 0 to 6 to be logged to RAM.
The following table lists the event levels of the Managed Switch:
Level Severity Name Description
7 Debug Debugging messages
6 Informational Informational messages only
5 Notice Normal but significant condition, such as cold start
4 Warning Warning conditions (e.g., return false, unexpected return)
3 Error Error conditions (e.g., invalid input, default used)
2 Critical Critical conditions (e.g., memory allocation, or free memory
error - resource exhausted)
1 Alert Immediate action needed
0 Emergency System unusable
