In this tutorial, we will go through a working example of a Python application auto-instrumented with OpenTelemetry. To keep things simple, we will create a basic “Hello World” application using Flask, instrument it with OpenTelemetry’s Python client library to generate trace data and send it to an OpenTelemetry Collector. The Collector will then export the trace data to an external distributed tracing analytics tool of our choice.
Last week, we spent some time talking to Gergely Orosz about our thoughts on what happens when an incident is over, and you're looking back on how things went. If you haven't read it already, grab a coffee, get comfortable, and read Gergely's full post Postmortem Best Practices here. But before you do that, here's some bonus material on some of our points.
The Docker images we provide for both Icinga 2 and Icinga Web 2 already contain quite a number of modules. For example, the Icinga Web 2 image contains all the Web modules developed by us. But one of the main benefits of Icinga is extensibility, so you might want to use more than what is already included. This might be some third-party module or a custom in-house module.
People are more than happy to talk about their successes, but if you ask them about their failures, they can be much more hesitant to share. Failure is a subject that, interestingly enough, is entangled with the emotion of shame. Yet it’s integral to achieving anything novel, and the learnings that come from failure are unparalleled. So, let’s find ways to get more comfortable with failing, and figure out why people fear it.
Today, we announced that Honeycomb has raised $50M in Series C funding, in a round led by Insight Partners and joined by all existing investors from our Series B. We’re using this investment to support the growth of our customers and community, ensure the benefits of observability can be realized by all engineering teams, and expand the ways we can better serve you.
Flux is a CNCF based open source stack of tools. Flux focuses on making it possible to keep Kubernetes clusters and cloud-native applications in sync with external resources and definitions hosted in environments such as GitHub. Implementing tools like FluxCD should enable you to achieve results such as: The results above can bring obvious benefits, and many teams are adopting FluxCD as their tool of choice for GitOps.
