 [Datadog](https://www.datadoghq.com/) is a hosted infrastructure monitoring platform. This chart adds the Datadog Agent to all nodes in your cluster via a DaemonSet. It also optionally depends on the [kube-state-metrics chart](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-state-metrics). For more information about monitoring Kubernetes with Datadog, please refer to the [Datadog documentation website](https://docs.datadoghq.com/agent/basic_agent_usage/kubernetes/).
