Troubleshooting Terracotta clusters with the TMC includes passive monitoring through viewing events and statistical trends using the monitoring panels as well as proactively investigating logs and thread dumps. For information about viewing events and monitoring system trends, see Using the Monitoring Tab. For more information about examining logs and generating thread dumps, see Viewing Server Logs and Generating Thread Dumps.

If a cluster crosses certain resource thresholds, it might enter a mode of limited functionality to prevent a crash. For more information about this behavior, see Understanding Special TSA Modes.
