Integrating Prometheus with SAP's Enterprise Software for Kubernetes Monitoring: A Step-by-Step Guide

Pre-requisites

Kubernetes Cluster:

  • Have a running Kubernetes cluster. #### kubectl:
  • Installed and configured to interact with your cluster. #### Helm:
  • Installed, for easier package deployment.

Deployment

Step 1: Install Prometheus Operator

  • Open your terminal and run:
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm install prometheus prometheus-community/kube-prometheus-stack
Enter fullscreen mode Exit fullscreen mode

Step 2: Check Installation

  • Confirm that Prometheus is running.
kubectl get pods -n default
Enter fullscreen mode Exit fullscreen mode

Step 3: Configure Service Monitors

  • Create a service-monitor.yaml file and specify what you need.
apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: sap-service-monitor
spec:
  endpoints:
  - port: http-metrics
  selector:
    matchLabels:
      app: sap-service
Enter fullscreen mode Exit fullscreen mode
  • Apply the Service Monitor.
kubectl apply -f service-monitor.yaml
Enter fullscreen mode Exit fullscreen mode

Step 4: Open Prometheus Dashboard

  • Use port-forwarding to access the dashboard.
kubectl port-forward svc/prometheus-kube-prometheus-prometheus 9090:9090
Enter fullscreen mode Exit fullscreen mode
  • Open http://localhost:9090/targets. You should see your SAP service.

Usage

Step 1: Access Grafana

  • Port-forward to Grafana.
kubectl port-forward svc/prometheus-grafana 3000:80

Enter fullscreen mode Exit fullscreen mode
  • Open http://localhost:3000. Default login is admin/admin.

Step 2: Import Dashboard

  • Go to Dashboards > Import and pick a Kubernetes-focused dashboard.

Step 3: Set Alerts

  • In Prometheus, go to Alerts and set your rules.

Step 4: Test

  • Deploy a busy pod or two and watch the metrics to validate the setup.

And there you go! This guide should help you monitor Kubernetes clusters in an SAP environment with Prometheus.
