Dstat usage

[vj_linux]

Im using dstat -tcglmrsy -D sdi --vm --disk-util --disk-tps --output file, i tried a few combinations but could not find how to get the read/write per second on the disk throughput.
I wanted details such as from iostat output:
07-03 12:56:45 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn
07-03 12:56:45 sdi 1454.00 1488384.00 0.00 1488384 0

I want to combine this data with other data from dstat , can you please tell me how? Any help is appreciated!!
