My guess is that you don't have full API access, or if it doesn't display hashrates... no API access. Make sure that either this is in the miner arguments:
--api-listen --api-allow W:127.0.0.1
or that these two lines are in the config file:
"api-listen" : true,
"api-allow" : "W:127.0.0.1"
(you may need to put a comma at the end of the second line depending on where in the config file you place it.)
I didn't intend for it to notify the user and log this continuously, just an oversight on my part because I got used to always having full API access enabled. If someone chooses to give read-only access (for some reason?) then it should provide info without nagging them, it will just be limited on making changes to the miner (GPU, Pool, etc), although even with read-only access it will still be able to start, stop, and restart the miner. This is fixed in 1.1.4, which should be available this weekend.
