What type of information does a TSC log for troubleshooting?

The Tactical Session Controller (TSC) plays a critical role in managing sessions within a network, and logging specific types of information is essential for effective troubleshooting. The correct choice involves logging signaling messages and errors.

Signaling messages are vital as they carry the necessary information about the initiation, maintenance, and termination of communication sessions. These messages provide insights into the interactions between different network nodes, indicating what commands are being executed and how the system responds.

Errors logged by the TSC are equally important; they reveal issues that may have occurred during session management, such as failed connections or unexpected behavior. By analyzing both signaling messages and error logs, technicians can identify trends, diagnose issues swiftly, and implement corrective measures to enhance system performance and reliability.

In contrast, options that focus solely on user feedback, successful session details, or file download/upload activities would not provide the comprehensive visibility needed for troubleshooting purposes. User feedback can be subjective and may not point directly to technical issues; successful session details do not reflect potential problematic scenarios, and file transfers are generally separate processes outside the signaling and error management scope of TSC functions. Thus, logging signaling messages and errors is the most effective way to facilitate troubleshooting within the TSC framework.
