Which of the following concepts does not relate to the functionality of network monitoring tools?

Data compression is not directly related to the core functionality of network monitoring tools. Network monitoring typically focuses on analyzing, detecting, and reporting on network traffic, performance, and security events.

Traffic analysis involves examining network data flow to understand bandwidth usage, detect bottlenecks, and identify unusual patterns. Intrusion detection relates to identifying potentially malicious activities within the network through various techniques, such as analyzing traffic patterns for signs of attacks. Log consolidation involves aggregating logs from different sources for easier analysis and monitoring.

In contrast, data compression primarily deals with reducing the size of data for efficient storage or transmission, rather than analyzing or monitoring traffic, making it irrelevant in the context of network monitoring tools.
