There's your answer to "Why won't you host your server logs (which are usually key for troubleshooting flaming boxen)?"
Everything in life is a tradeoff. If you entrust your logs to us, you run the risk that we have an outage or failure of some sort. On the other hand, internal systems can fail as well. We hope to serve people who prefer not to carry the responsibility of maintaining their own monitoring infrastructure, and/or are interested in the features and performance we provide.
Well, yeah.
Out of curiosity, what is your target customer? People running their own dedis probably are alright to grudgingly setup a monitoring solution, and people who are just using the ~=cloud=~ probably don't care.
What's your ideal customer?
