Heatmaps and more heatmaps

I’ve talked with a few Cloud Analytics users who weren’t sure how to interpret the latency heatmaps. While we certainly aren’t the first to use heatmaps in performance analysis, they’re not yet common and they can use some explanation the first time you see them. I posted a simple example a few weeks ago, but video’s worth a thousand words so I’ve made a screencast covering a different example and explaining the heatmap basics:

Thanks to Deirdré for posting the video.

Finally, here are a few completely unrelated but interesting examples of heatmaps:

The stock market return heatmap particularly emphasizes how much information you can pack into a heatmap (nearly 4000 data points, all individually represented) in a way that readers can still make sense of.

Presenting at OSCON Data 2011

Brendan‘s and my proposal for OSCON Data 2011 has been accepted! The talk is called “Design and Implementation of a Real-Time Cloud Analytics Platform“. We’ll dive into the implementation of Cloud Analytics with particular focus on the design considerations that allow it to work in real-time on a large production cloud.

We’ll also cover some real-world case studies of people using CA to understand application behavior. If you’ve used no.de‘s Analytics to look at your application, we’d love to hear from you! Leave a comment, tweet @dapsays, or email dap at joyent.
