Database Software

There was a previous post about a nifty tool based on collectl and as the author of collectl, I thought I'd just post a general note to ask if anyone has any questions about using collectl. It has a zillion switches and options and when coupled with colmux can do a pretty decent job of monitoring clusters, allowing you to get a 'top-like', sorted view of almost any linux metric. Then when you toss in 'colplot' for web-based plotting, things get even more interesting. Unfortunately all this flexibility comes at the cost of complexity. I like to think that most of the simple things are pretty easy to do, and most people only do the simple things, but the more complex ones can be pretty slick but are still tricky or even unknown.
