Quick Guide for Datadog Agent on Kubernetes for Logs

The Datadog Agent on Kubernetes collects logs, metrics, and traces from your cluster and sends them to Datadog for monitoring and analysis. This guide walks you through installing the agent using Helm, configuring pod-level metrics collection with annotations, and enabling log ingestion from your containerized applications.

Add the Datadog Helm repository

helm repo add datadog https://helm.datadoghq.com
helm repo update

Configure `datadog-values.yaml`

For pod-level metrics, add Datadog annotations to enable scraping.
