+# Monitoring Managed Cloud with Prometheus and Grafana
+
+This tutorial will guide you through the process of setting up Prometheus and Grafana to monitor Qdrant databases running in Qdrant Managed Cloud.
+
+## Prerequisites
+
+This tutorial assumes that you already have a Kubernetes cluster running where you want to deploy your monitoring stack, and a Qdrant database created in Qdrant Managed Cloud. You should also have `kubectl` and `helm` configured to interact with your cluster.
+
+## Step 1: Install Prometheus and Grafana
+
+If you haven't installed Prometheus and Grafana yet, you can use the [kube-prometheus-stack](https://artifacthub.io/packages/helm/prometheus-community/kube-prometheus-stack) Helm chart to deploy them in your Kubernetes cluster.
+
+A minimal example of installing the stack:
+  
+```bash
+helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
+
+helm install prometheus prometheus-community/kube-prometheus-stack --namespace monitoring --create-namespace
+```
+
+This command will install Prometheus, Grafana, and all necessary components into a new `monitoring` namespace.
+
+## Step 2: Configure Prometheus to Scrape Qdrant Metrics
+
+To monitor Qdrant, you need to configure Prometheus to scrape metrics from the Qdrant database. You can do this by creating a `ScrapeConfig` resource in your Kubernetes cluster. The API key to authenticate at your Qdrant database should be stored in a Kubernetes Secret. A read-only API key is sufficient for monitoring purposes.
+
+```yaml
+apiVersion: v1
+kind: Secret
+metadata:
+  name: qdrant-cluster-api-key
+  namespace: monitoring
+  labels:
+    app: qdrant-cluster
+stringData:
+  apiKey: "a-read-only-api-key"
+---
+apiVersion: monitoring.coreos.com/v1alpha1
+kind: ScrapeConfig
+metadata:
+  name: qdrant-cluster
+  namespace: monitoring
+  labels:
+    app: qdrant-cluster
+    release: prometheus
+spec:
+  metricsPath: /sys_metrics
+  scrapeInterval: 30s
+  scheme: HTTPS
+  authorization:
+    type: Bearer
+    credentials:
+      name: qdrant-cluster-api-key
+      key: apiKey    
+  staticConfigs:
+    - labels:
+        job: prometheus
+      targets:
+        - your-cluster.europe-west3-0.gcp.cloud.qdrant.io:443
+```
+
+## Step 3: Access Grafana
+
+Once Prometheus is configured to scrape metrics from Qdrant, you can access Grafana to visualize the metrics.
+
+Get the Grafana 'admin' user password by running:
+
+```bash
+kubectl --namespace monitoring get secrets prometheus-grafana -o jsonpath="{.data.admin-password}" | base64 -d ; echo
+```
+
+Access the Grafana dashboard by port-forwarding:
+
+```bash
+export POD_NAME=$(kubectl --namespace monitoring get pod -l "app.kubernetes.io/name=grafana,app.kubernetes.io/instance=prometheus" -oname)
+kubectl --namespace monitoring port-forward $POD_NAME 3000
+```
+
+Now you can open your web browser and go to `http://localhost:3000`. Log in with the username `admin` and the password you retrieved earlier.
+
+## Step 4: Import Qdrant Dashboard
+
+Qdrant Cloud offers an example Grafana Dashboard on the [Qdrant GitHub repository](https://github.com/qdrant/qdrant-cloud-grafana-dashboard). This comes with built in views and graphs to get you started with monitoring your Qdrant Clusters.
+
+To import the dashboard:
+
+1. In Grafana, go to "Dashboards" and click on "New" -> "Import".
+2. Copy and paste the dashboard JSON from the Qdrant GitHub repository.
+3. Click "Load" and then "Import".
