Queue Analysis Report
Queue analysis report provides a complete overview of resources utilized by a specific queue. You can generate the report for a single queue, multiple queues, and custom regex, which considers only a particular queue that matches the regex. It is relevant to users who want additional min/max, memory/vcores metrics in the analysis.
