When things go sideways: Troubleshooting the OpenTelemetry Operator
Blog post from New Relic
The OpenTelemetry Operator is designed to streamline the management of OpenTelemetry in Kubernetes environments by automating the deployment and configuration of Collectors and facilitating zero-code instrumentation for applications. It aids in automatically injecting and configuring instrumentation into Kubernetes pods, enabling telemetry data collection without altering source code. The Operator supports various deployment patterns and leverages the Open Agent Management Protocol for consistent observability settings across different vendors. Before installation, a Kubernetes cluster with a cert-manager is required, and the Operator can be installed using kubectl or Helm. The blog provides detailed guidance on installation, deployment, and troubleshooting common issues related to Collector deployment and auto-instrumentation. It emphasizes the importance of correctly configuring endpoints and checking for proper deployment order and annotations to ensure successful telemetry data processing.
