May 2018 Newsletter
May was a busy month for us! We have a new version for the server components, 117 PRs opened across all our repositories and 63 closed issues.
Jaeger Project Updates
We have a new release this month: v1.5.0. It ships with the ability to adjust static sampling probabilities per operation, better metric names and a new CLI option to limit the number of traces stored by the in-memory storage, as well as a health-check endpoint for our standalone binary, by first-time contributor Eundoo Song (@eundoosong). Thanks!
Thanks to hard work by Benjamin Krämer (@Falco20019) and Christian Weiss (@cwe1ss), Jaeger now has an official client for C# and .NET that has full feature parity with the Java client.
And just as the month was closing, Jaeger has been selected as the default tracing backend for Istio as of v0.8.0 when installing via Helm. Check it out by passing --set tracing.enabled=true!

Beyond OpenTracing • Allison Richardet
A cluster is a busy place, and lots can happen. Microservices, containers, polygot persistence, schedulers, and so on have enabled organizations to rapidly deploy a variety of applications. We can get up and running quickly, but then progress halts if we can’t understand our system. In order to keep moving forward, we need to enforce structure in the right places, while not constraining the benefits of microservices. Just as event sourcing can help us structure communication among services, an evolvable grammar can structure our measurements to enable powerful insights and analytics. This grammar can help us increase cardinality in our logging and allow more tools to provide insight into what is going on. In this talk, we will walk through how to use logging, OpenTracing, and grammar to improve event collection for later analysis.

CloudNativeCon+KubeCon EU 2018 • How We Used Jaeger and Prometheus to Deliver Lightning-Fast User Queries by Bryan Boreham
This talk comes from practical experience of running a cloud-based SAAS under Kubernetes for the last two years. Prometheus is good for the big picture view of how things are running, while Jaeger acts like a microscope on the internal workings of your system.
You will learn about:
* Setting up Jaeger and Prometheus in your Kubernetes cluster
* Inspecting Jaeger and Prometheus output for tell-tale signs of trouble
* Instrumenting your code (with examples in Go) for more detail
* Applying the information gained to optimise your code and tune your system
