Grafana Agent Metrics Kubernetes Quickstart
In this guide you’ll learn how to deploy the Grafana Agent into a Kubernetes cluster and configure it to scrape the
cadvisor endpoints on your cluster Nodes. You’ll also configure the Agent to ship these scraped metrics to Grafana Cloud using its
Note: The instructions in this quickstart guide mirror those from the Grafana Cloud Kubernetes Integration. To get started with Grafana Agent and the Kubernetes Integration, please click on the lightning bolt in the left-hand navigation panel of your hosted Grafana instance and follow the instructions for installing the Kubernetes Integration. The Kubernetes Integration provides preconfigured Kubernetes manifests for rolling out an Agent Deployment into your cluster to scrape metrics from
kubeletendpoints, as well as prebuilt dashboards to visualize these metrics.
Kubernetes is an open-source container orchestration system that automates software container deployment, scaling, and management. By default, Kubernetes exposes several Prometheus-compatible metrics endpoints on both Nodes and the Control Plane.
You’ll collect Node
kubelet metrics using the Grafana Agent, a lightweight telemetry collector based on Prometheus that only performs its scraping and
remote_write functions. The Agent can also collect metrics, logs, and traces for storage in Grafana Cloud and Grafana Enterprise, as well as OSS deployments of Loki (logs), and Tempo (traces), Prometheus (metrics), and Cortex (metrics).
Note: The Agent Operator (beta) can also help you get up and running with Grafana Agent and Kubernetes.
Before you begin, you should have the following available:
- A Kubernetes cluster with role-based access control (RBAC) enabled.
- A Grafana Cloud account. To create an account, please see Grafana Cloud and click on Start for free.
kubectlcommand-line tool installed on your local machine, configured to connect to your cluster. You can read more about installing
kubectlin the official documentation.
Step 1: Deploy Grafana Agent resources
In this step you’ll install the Grafana Agent and its required resources into your cluster.
Run the following command from your shell to install the Grafana Agent into the
default Namespace of your Kubernetes cluster:
MANIFEST_URL=https://raw.githubusercontent.com/grafana/agent/main/production/kubernetes/agent-bare.yaml NAMESPACE=default /bin/sh -c "$(curl -fsSL https://raw.githubusercontent.com/grafana/agent/release/production/kubernetes/install-bare.sh)" | kubectl apply -f -
This installs a single replica Grafana Agent Deployment into your cluster and configures RBAC permissions for the Agent. If you would like to deploy the Agent into a different Namespace, change the
NAMESPACE=default variable, ensuring that this Namespace already exists.
In the next step, you’ll configure the Agent.
Step 2: Configure Grafana Agent
Paste the following script into your shell and run it to configure the Grafana Agent:
cat <<'EOF' | kind: ConfigMap metadata: name: grafana-agent apiVersion: v1 data: agent.yaml: | server: http_listen_port: 12345 prometheus: wal_directory: /tmp/grafana-agent-wal global: scrape_interval: 15s external_labels: cluster: YOUR_CLUSTER_NAME configs: - name: integrations remote_write: - url: YOUR_REMOTE_WRITE_URL basic_auth: username: YOUR_REMOTE_WRITE_USERNAME password: YOUR_REMOTE_WRITE_PASSWORD scrape_configs: - job_name: integrations/kubernetes/cadvisor bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token kubernetes_sd_configs: - role: node metric_relabel_configs: - action: drop regex: container_([a-z_]+); source_labels: - __name__ - image - action: drop regex: container_(network_tcp_usage_total|network_udp_usage_total|tasks_state|cpu_load_average_10s) source_labels: - __name__ relabel_configs: - replacement: kubernetes.default.svc:443 target_label: __address__ - regex: (.+) replacement: /api/v1/nodes/$1/proxy/metrics/cadvisor source_labels: - __meta_kubernetes_node_name target_label: __metrics_path__ scheme: https tls_config: ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt insecure_skip_verify: false server_name: kubernetes - job_name: integrations/kubernetes/kubelet bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token kubernetes_sd_configs: - role: node relabel_configs: - replacement: kubernetes.default.svc:443 target_label: __address__ - regex: (.+) replacement: /api/v1/nodes/$1/proxy/metrics source_labels: - __meta_kubernetes_node_name target_label: __metrics_path__ scheme: https tls_config: ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt insecure_skip_verify: false server_name: kubernetes EOF (export NAMESPACE=default && kubectl apply -n $NAMESPACE -f -)
If you deployed the Agent into a non-default Namespace in the previous step, replace
NAMESPACE=default in this command with the new Namespace. Be sure to also replace the capitalized variables beginning in
This ConfigMap configures the Agent to scrape
kubelet endpoints in your cluster and ship scraped metrics to Grafana Cloud.
To learn more about configuring the Agent, please see Configure Grafana Agentfrom the Agent docs. After deploying the
ConfigMap, the Grafana Agent should start.
Step 3: Restart the Grafana Agent
After modifying the Agent’s configuration, you will need to restart the Agent Pod to pick up configuration changes. Use
kubectl rollout to restart the Agent:
kubectl rollout restart deployment/grafana-agent
You’ve now deployed the Agent into your cluster, have configured it to scrape the
cadvisor endpoints, and are shippping these scraped metrics to Grafana Cloud using its
From here, you can deploy additional Agents to collect logs and traces in your Kubernetes clusters.
