# Part 6: Observability stack setup to monitor

*   ## **How to monitor EKS cluster, Kubernetes components, and workloads using Prometheus and Grafana via HELM (on the master machine)**
    
*   ### Install Helm Chart
    

```bash
curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
chmod 700 get_helm.sh
./get_helm.sh
```

*   **Add Helm Stable Charts for Your Local Client**
    

```bash
helm repo add stable https://charts.helm.sh/stable
```

*   **Add Prometheus Helm Repository**
    

```bash
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
```

*   ### Create Prometheus Namespace
    

```bash
kubectl create namespace prometheus
kubectl get ns
```

*   Install Prometheus using Helm
    

```bash
helm install stable prometheus-community/kube-prometheus-stack -n prometheus
```

*   Verify Prometheus installation
    

```bash
kubectl get pods -n prometheus
```

*   **Check the services file (svc) of the Prometheus**
    

```plaintext
kubectl get svc -n prometheus
```

*   **Expose Prometheus and Grafana to the external world through Node Port**
    

> ***\[Note\] change it from Cluster IP to NodePort after changing make sure you save the file and open the assigned nodeport to the service.***

```bash
kubectl edit svc/stable-kube-prometheus-sta-prometheus -n prometheus
```

**Verify service**

```bash
kubectl get svc -n prometheus
```

*   **Now, let’s change the SVC file of Grafana and expose it to the outer world**
    

```bash
kubectl edit svc stable-grafana -n prometheus
```

*   **Check the Grafana service**
    

```bash
kubectl get svc -n prometheus
```

*   **Access the Grafana with** `<public-ip-of-master>:32108` **and Prometheus with** `<public-ip-of-master>:31521`
    

> Note - First port-forward through the below command:

```plaintext
kubectl port-forward svc/stable-grafana 32108:80 -n prometheus --address 0.0.0.0 &

kubectl port-forward svc/stable-kube-prometheus-sta-prometheus 31521:9090 -n prometheus --address 0.0.0.0 &
```

*   **Prometheus:**

*   **Get a password for Grafana**
    

> \[Note\] Username: admin

```plaintext
kubectl get secret --namespace prometheus stable-grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo
```

*   **Now, view the Dashboard in Grafana**
