You can refer to the entire code on this application in our Fission GitHub samples repo

You can find the code to this example here. For any issues or clarification, you can reach out to the author.

As a developer, you already know that you simply cannot start coding without setting up the environment. So, let's look into the pre requisites that are required to send traces to Datadog using OpenTelemetry and Fission. The entire source code for this application can be found in this OpenTelemetry Datadog Sample Repo.

We used Lightstep’s Prometheus Kubernetes OpenTelemetry Collector to get these Metrics into Lightstep. This Helm chart is inspired by kube-prometheus-stack, but with one crucial difference -- no Prometheus! We’re able to use recent enhancements to the OpenTelemetry Operator for Kubernetes such as support for Service Monitors in order to scrape Prometheus metrics from pods, system components, and more.
