I think you can look at http:///minera/index.php/app/stats URL, that should give you each chip stat.
Thanks for your help

The only thing i get is this per blade:
{"ttyACM3":{"frequency":800,"accepted":2489,"rejected":2,"hw_errors":1,"shares":3611400,"hashrate":2701197,"last_share":1403308505,"serial":"48FC66603135"}
I think is just the total
