cfstats - check Read Count per minute

[Marcus Both]

Hi, 
I am checking how many "Read Count" are made per minute as follows way:

$ ./nodetool -h 127.0.0.1 cfstats
Keyspace: KSTEST
        Read Count: 412303
(...)
sleep 60
$ ./nodetool -h 127.0.0.1 cfstats
Keyspace: KSTEST
        Read Count: 462555
(...)

$ echo "462555 - 412303"| bc
50252

And then I can see how many Read are made per minute, 50.252!
Is there another way to check this?

Tks.
