We have a job that has been running but none of the AWS resource metrics for the EKS, EC2, MSK and EBS show any bottlenecks. I have multiple 8 cores allocated but only ~2 cores are used. Most of the memory is not consumed. MSK does not show much use. EBS metrics look mostly idle. I assumed I'd be able to see whichever resources is a bottleneck.
Is there a good way to diagnose where the bottleneck is for a Flink job?
