Try one or more of the apps listed on page 1 of this thread then you could get a notification if one of your machines drops below a certain hash rate that you set. Then maybe you will find that you don't have to look at the website so often.
I currently get 3 notices when one of my miners drops below the hashrate I set; a push notice from the Apple app to my iphone; a text messagew to my phone from zachmonroe web site, and an email from the zachmonroe website. I understand that the minergain web site does the same thing and although I have never tried the android app, I hear it also sends out these notices as well.
....
thanks for that, i will check it
