How to calculate the throughput usage of AWS EBS volume
We have a hadoop cluster running on AWS EC2 instances. Configured 16T st1 volume in datanodes for HDFS usage.
We need to understand, what is the maximum throughput hitting on this st1 volumes.
Since CloudWatch is covering data on 5 mins interval, the values are being averaged out and cannot be trusted.
I came to know that 'iostat -txm 1' can be used to get the real time usage and make out current throughput. But i have failed to understand how to calculate throughput from this result.
I need to calculate the throughput using iostat ?
