Input OnTime

I have a compressor input form 0 (off) to 100 (on). I want to be able to now the run-time for that compressor daily with a total monthly. We want to close monitor the temps on the space and make the adjustment to minimize the operation of the compressor.

Right now as the input on time is configure is not possible, I know very well the controllers but I am newbie on emoncsm, I already have a Raspberry with a HHD running and is getting the input from my controller. Can some one let me know what I need to do?
