I use Splunk, and am a big fan of everything except the cost. It works well, but it gets very expensive, very quickly when you grow beyond the 500MB/day free limit. I'm basically only collecting very limited usage log type information, because of that limit.

It's not just the size limit that's a problem in Splunk, the user accounting is only in the paid version - the free version is completely open for anybody to browse and it's up to you to secure it.

Granular access controls are nice under certain scenarios, but adding a basic ACL isn't hard. "Can use Splunk" and "Can't use Splunk" is enough control for me at the moment, fortunately.
