# MONITORING

# 📊 Monitoring Stack Setup with Prometheus, Loki, and Grafana on Kubernetes

This guide walks through the process of deploying a full monitoring stack (Prometheus, Loki, and Grafana) into a Kubernetes cluster using Helm.

***

## 🧾 Prerequisites

* A running Kubernetes cluster
* `kubectl` and `helm` installed and configured
* Cluster access with sufficient privileges

***

## 🛠️ Step 1: Prepare Namespace and Repositories

Create a namespace for the monitoring stack and add the required Helm repositories:

```bash theme={null}
kubectl create namespace monitoring

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

***

## 🔍 Step 2: Explore Loki Chart and Customize Values

Search for Loki in the Helm repo:

```bash theme={null}
helm search repo loki
```

Export default values for customization:

```bash theme={null}
helm show values grafana/loki-stack > loki.yaml
```

> **NOTE**: In `loki.yaml`, modify the `grafana` section:
>
> ```yaml theme={null}
> grafana:
>   enabled: true
>   image:
>     tag: latest
> ```
>
> This enables Grafana and optionally pulls the latest image tag.

***

## 🚀 Step 3: Deploy Loki Stack with Helm

Install or upgrade the Loki stack using the customized values:

```bash theme={null}
helm upgrade --install --values loki.yaml loki grafana/loki-stack -n monitoring --create-namespace
```

Loki UI will be available at the following internal URL:

```bash theme={null}
http://loki.monitoring.svc.cluster.local:3100
```

***

## 📈 Step 4: Install Prometheus

```bash theme={null}
helm install prometheus prometheus-community/prometheus -n monitoring
```

Prometheus UI will be available at the following internal URL:

```bash theme={null}
http://prometheus-server.monitoring.svc.cluster.local
```

***

## 📊 Step 5: Install Grafana

```bash theme={null}
helm install grafana grafana/grafana -n monitoring
```

Retrieve Grafana admin password:

```bash theme={null}
kubectl get secret --namespace monitoring grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo
```

Expose Grafana locally via port-forward:

```bash theme={null}
kubectl port-forward service/grafana --namespace monitoring 3000:80
```

Alternatively, expose via NodePort (not recommended for production):

```bash theme={null}
kubectl patch svc grafana -n monitoring -p '{"spec": {"type": "NodePort"}}'
```

Access Grafana at `http://<NodeIP>:<NodePort>`

***

## 📉 Recommended Grafana Dashboards

You can import the following dashboards from Grafana Labs using their Dashboard IDs:

| Dashboard Name                 | Dashboard ID |
| ------------------------------ | ------------ |
| Kubernetes Addons (Prometheus) | 19105        |
| Kubernetes Cluster (Global)    | 15757        |
| Kubernetes Namespaces View     | 15758        |
| Kubernetes Nodes View          | 15759        |
| Kubernetes Pods View           | 15760        |
| NVIDIA DCGM Exporter Dashboard | 12239        |
| Kubernetes Nodes               | 8171         |
| Kubernetes Pod Metrics         | 747          |
| Kubernetes App Metrics         | 1471         |
