How do I enforce policy-as-code for OpenTelemetry using OPA and Conftest?

Enforcing policy-as-code for OpenTelemetry using Open Policy Agent (OPA) and Conftest allows organizations to validate their observability setup against predefined policies. This integration ensures compliance and best practices in monitoring applications.

Description: This document describes how to implement policy-as-code practices for OpenTelemetry configurations using Open Policy Agent and Conftest, enabling infrastructure teams to enforce monitoring standards effectively.
// Example of a Rego policy to ensure all traces have a minimum duration package opentel violation[{"msg": msg}] { trace := input.traces[_] trace.duration < 1000 # Duration in milliseconds msg := sprintf("Trace %v has a duration lower than the minimum required", [trace.id]) }
