7. Kibana Dashboard

  • Once the filebeat starts listening, an index will be created or updated on the elastic configured and the pushed logs can be seen.
  • In order to create a dashboard, you will need to build visualizations. Kibana has two panels for this
  • One called Visualize and
  • Another called Dashboard
  • In order to create your dashboard, you will first create every individual visualization with the Visualize panel and save them.

8.Successful Installation

kubectl get all -n <namespace>
kubectl port-forward svc/kibana-kb-http 5601:5601
- All the pods should be up and running - Kibana Ui with filebeat index should be seen (after beat installation)
