For each container, the tcp_queue_length integration returns the read/write buffer’s fill percentage of the busiest TCP connection. For example, if a container has three TCP connections, for which their read buffers (that is, receive queues) are 40%, 25%, and 80% full (respectively), the metric tcp_queue.read_buffer_max_usage_pct returns the maximum, 0.8 (80%).
