What driving an old jalopy taught me about monitoring

Driving old, beat-up cars is both a treat and a nightmare, especially when it comes to figuring out why they’ve stopped working (this time). In many ways, diagnosing issues with any old car feels not-at-all dissimilar to monitoring for and diagnosing failures in software.

My book, along with several other incredible books, is on sale via a Humble Bundle right now. There’s ~$600 worth of top-notch books in the bundle–all yours at a fraction of the price. Bonus: a portion of the proceeds go to support Code For America. Seems like a win for everyone.

Flux 0.7 Technical Preview - InfluxData

I know a whole lot of you are InfluxDB users, so this will be useful: the new Flux language is now in InfluxDB 1.7, but disabled by default. Turn it on and have some fun playing with the query language. Personally, I’m a huge fan of the explicit-over-implicit syntax. The Grafana datasource plugin is still in beta, though.

Heatmaps Make Ops Better

If you’re still wondering why heatmaps are awesome, this article has some great graphs to show their value and why other visualizations fall short for some data/questions.

Say it with me, now: stop aggregating percentiles.

FlameScope Pattern Recognition

You’re a fan of flame graphs, right? The author of those, Brendan Gregg, has come up with a new visualization, subsecond offset heatmaps, and a tool to help with them: FlameScope.

Measuring Performance With Server Timing

This article goes into some depth on a W3C proposal currently making its way through committee: the HTTP Server-Timing header. The header is intended to pass arbitrary metrics via the HTTP response, such as duration, cache result, or whatever you want. The examples section in the proposal gives some ideas about what’s possible. I’m really excited about this one.

I’m sure most of you use what Writely turned into, though: Google Docs. Now one of founders behind the groundbreaking-at-the-time Writely (seriously, do you remember what we did before gdocs?!) has turned their attention to the world of logging and monitoring. You should check it out.
