Working with Logs
The log messages contain the time of event, severity, source component, and any details generated
by the source component. Log messages are divided into three groups:
• Controller logs
• Wireless AP logs
• Login logs
Log Severity Levels
Log messages are classified at four levels of severity:
• Information (the activity of normal operation)
• Minor (alarm)
• Major (alarm)
• Critical (alarm)
The alarm messages (minor, major or critical log messages) are triggered by activities that meet
certain conditions that should be known and dealt with. The following are examples of events on
the SCALANCE IWLAN Controller that generate an alarm message:
• Reboot due to failure
• Software upgrade failure on the SCALANCE IWLAN Controller
• Software upgrade failure on the Wireless AP
• Detection of rogue access point activity without valid ID
• Availability configuration not identical on the primary and secondary SCALANCE IWLAN
Controller
If SNMP is enabled on the SCALANCE IWLAN Controller, alarm conditions will trigger a trap in
SNMP (Simple Network Management Protocol). An SNMP trap is an event notification sent by the
managed agent (a network device) to the management system to identify the occurrence of
conditions.
Note:
The log statements Low water mark level was reached and Incoming message dropped, because of the
rate limiting mechanism indicate that there is a burst of log messages coming to the event server and the
processing speed is slower than the incoming rate of log messages. These messages do not indicate that the
system is impaired in any way.
