What does the total user minutes metric refer to in relation to Mist statistics?

The total user minutes metric refers to the total number of minutes for which Mist has collected statistics for each client. This metric provides insights into the duration of time that the system has ongoing statistical data for individual clients, rather than just the total minutes they were connected or the average time they spent connected. It allows network administrators to understand how long data has been gathered, which can be crucial for monitoring performance, identifying trends, and making informed decisions based on client activity over time. This approach to measuring user engagement can help optimize network resources and enhance performance analysis.
