As far as I understand there is no "hashrate accepted by the wallet". This is not a pool where you get lots of accepted shares so you can monitor only the hashrate seen in the miner itself. When you start to get accpeted blocks in the wallet you can calculate the effective hashrate based on the current difficulty but this will be very inaccurate because of variance unless you have a huge farm.
Ok thank! but they are very interesting to see work of your GPU on your wallet to check your rig work great
