In the last post I introduced you to Riemann. I mentioned streams in that post and how they are at the heart of Riemann’s power. However I only provided a vague teaser of streams and left you having to go fish for yourself. In this post I’m going to build on our example Riemann configuration. I’ll show you how to do simple service management with streams and introduce you to Riemann’s state table: the index.

If only I had the theorems! Then I should find the proofs easily enough - Bernard Riemann For the last year I’ve been using nights and weekends to look to a variety of monitoring and logging tools. For reasons. I’ve spent a lot of hours playing with Nagios again (some years ago I wrote a book about it) as well as looking at tools like Sensu and Heka. One of the tools I am reviewing and am quite excited about is Riemann.

The Docker Book version 1.4.1 I am pleased to announce version 1.4.1 of The Docker Book is out! It has updates and fixes for the Docker 1.4.1 release. It also contains the errata and fixes you awesome folks keep sending in. How do I get the update? If you’ve bought the book you can use your existing download link to upload the updated book. If you have issues with the link then let me know and I’ll re-issue your link.

Over the course of the series I’ve talked about monitoring effectiveness, monitoring environments and check implementation, metrics, the primary tool people used in monitoring and the demographics of the survey. In this last post I am providing the anonymized source data that I based my analysis on. It’s in CSV form and comes directly from Survey Monkey. The only data I have removed is the IP address of the respondents to make it anonymous.

In the last posts I talked about monitoring environments and check implementation, metrics, the primary tool people used in monitoring and the demographics of the survey. In this post I am going to look at the questions around the effectiveness of monitoring, how people handle alerting and the use of configuration management software. As I’ve mentioned in previous posts, the survey got 1,016 responses of which 866 were complete and my analysis only includes complete responses.
