Enabling System Logging

The access point supports a logging process that can control error messages
saved to memory or sent to a server. The logged messages serve as a valuable
tool for isolating access point and network problems.
The following table lists the error message levels from the most severe
(Emergency) to least severe (Debug). The message levels that are logged
include the specified minimum level up to the Emergency level.
Error Level Description
Emergency System unusable
Alert Immediate action needed
Critical Critical conditions (e.g., memory allocation, or free memory error -
resource exhausted)
Error Error conditions (e.g., invalid input, default used)
Warning Warning conditions (e.g., return false, unexpected return)
Notice Normal but significant condition, such as cold start
Informational Informational messages only
Debug Debugging messages
The access point error log can be viewed using the Web interface. The Web
interface displays the last 128 messages logged in chronological order, from
the newest to the oldest. Since the Web interface has a limited amount of
memory for containing and displaying the event log, you should use the CLI
log command to view the complete list of logged events.
Log messages are only generated since the last reboot. Rebooting the access
point erases all previous log messages. Consider configuring the access point
to log messages to a server (see
"CLI: Setting Logging Parameters" on page 5-46).
