Java Multithreading and Parallel Programming Masterclass - Monitoring the Performance of a ThreadPool

This lecture introduces four essential methods for monitoring the thread pool executor: get pool size, get active count, get task count, and get completed task count. These methods help assess the performance and efficiency of the thread pool by providing metrics on the number of threads, active tasks, submitted tasks, and completed tasks. Understanding these metrics is crucial for optimizing thread pool usage and ensuring tasks are not rejected due to capacity issues. The lecture emphasizes the importance of monitoring these metrics to adjust the thread pool settings appropriately.

What are the potential consequences of having an underutilized thread pool?
