Creating dashboards in Prometheus for Queueing Theory basics allows you to visualize performance metrics such as wait times, queue lengths, and service efficiency. Below are the key concepts involved in using Prometheus for this purpose, with an accompanying example of the query syntax.
# Example Prometheus Query for Queue Length
total_queue_length = sum(increase(queue_length[5m]))
This query calculates the total queue length over the past 5 minutes, which can be useful for understanding system load and behavior over time.
