Rocana One free option provides up to 1TB of daily data volume for free.
Con Difficult to setup
Setup is not easy, the whole process is disjointed, with open source libraries that regularly change and out of date installation instructions.
Loggly QUICKLY overflows the 200mb daily free allowance.
Con The UI is confusing
The UI is very difficult to use, but it does offer a lot of features.
Con Timestamps are in UTC in the UI, and can't be converted
Loggly shows all timestamps in UTC, and the bookmarklet that's supposed to convert them to local time doesn't work.
Appears to be an expensive solution.
Con Doesn't run on a laptop
Well, maybe you can squeeze Rocana Ops on a laptop, but it is designed as a highly-distributed, fault-tolerant system and requires a Hadoop distro as the underlying platform.
