Final answer:
A downside of full process tracking includes system overhead, large volumes of data, and privacy concerns.
Step-by-step explanation:
One downside of full process tracking is the potential for significant overhead. When a system tracks every operation and process in detail, it requires extensive system resources, which can lead to reduced overall system performance. Besides, such granular tracking results in a huge volume of data, which can pose challenges in terms of data storage, management, and analysis. Finally, privacy concerns arise as well, especially if personal or sensitive information is being logged. It is essential to balance the need for security and system monitoring with these potential drawbacks.
