Debugging and Monitoring Fault Tolerance Activity

All state changes and IP address transfers are logged in the event logs of each relevant Traffic Manager. If email alerting is correctly configured on your Traffic Manager system, an email message is sent to the system administrator describing the state change and any IP address transfers that resulted.

For detailed debugging, you can enable the flipper!verbose setting. This setting causes each Traffic Manager to log each connectivity test, broadcast message sent and received, and is useful when determining why the fault tolerance behavior is not working as expected.

You can also view the Cluster Diagnosis section of the Diagnose page. This page contains information about broadcast messages not received correctly, and summarizes the system status if an error has occurred.
