Quick Guide for OTel Agent on Kubernetes for Metrics

The OpenTelemetry Collector on Kubernetes allows you to collect and export metrics, logs, and traces from your cluster to Kloudfuse for monitoring and analysis. This guide provides a sample configuration file that you can use as a starting point, with specific attention to setting the correct protocol depending on whether TLS is enabled in your environment.

Use the following sample helm-values.yaml file to configure the OpenTelemetry Collector to export logs, metrics, and traces to Kloudfuse. Ensure that you correctly set the protocol as either https or http, based on TLS being enabled or disabled.
