Cassandra - dstat

I'm new to dstat and I'm currently using it to analyze the performance of Cassandra writes whilst an ingest is taking place.

Could someone please explain how I could read the outputs provided and the units used?

I have run dstat lrvn 10 to produce the image below.

For instance, what is the unit of io/total here. Is this a percentage or number of read/writes every 10 sec? Do the colours resemble anything?

dstat lrvn 10

Thanks Majd

io/total are the number of IOPs.

You can find this information documented in the plugin that you are using.
