More recent resolution:

2. echo "[network]" | sudo tee wsl.conf (Create wsl.conf file and add the first line).

Application Observability in Kubernetes with Datadog APM and Logging - A simple and actionable example

At Buffer, since we primarily use Datadog for Kubernetes and application monitoring, it's only fitting to complete the circle with Datadog APM and Logging. I had a chance to create a small example for the team and would very much love to share with the community.
