I've seen a few different "monitor servers from your phone" (web)apps over the years, and having tried them I don't really see the appeal. Phones have tiny screens and crippled input; you can't see much and you can barely navigate. I do see value in alerting, so maybe this is a good supplement to that? But it seems like if I get say an SMS alert "server634 at 98% memory" I'd be better off getting to a laptop because I can investigate far easier from there, let alone fix things. (Happy to hear from anyone using these, though; it does seem like I might be missing a better workflow)
