History File Management

I recently installed hobbit to monitor nodes in a cluster. It's a very good product - thanks to all who have worked on it!

I noticed after a while, that the hobbit home directory was growing in an apparently boundless fashion. On further investigation, I discovered that on one server, my history files had grown to several gigabytes. After a while, this growth becomes unsustainable.

Am I doing something wrong? How do others manage the growth of hobbit history and log files? I'm not referring to those in /var/log/hobbit - that's easy to handle with logrotate. I'm concerned about the directories associated with each client under the server data directory.

Thanks!
