Metricbeat data flow problem with Kibana

Elastic Stack Beats
,
1

Hi!
I recently deployed Elasticsearch with Kibana on Azure Kubernetes environment. After that I deployed Metricbeat and it seems fine, all pods are running without problem.

But I can not see any data flow to Kibana from Metricbeat. When I open the page below, MetricBeat's status seen Offline, after that if I click "Monitor with Metricbeat", I tried lots of different configs(localhost:9200 also) but none one them worked.

"ElasticSearch Home Page" --> "Monitor the stack" --> "Setup Monitoring with Metricbeat"

Metricbeat deployed from here ----> https://github.com/elastic/beats/blob/master/deploy/kubernetes/metricbeat-kubernetes.yaml

Pods and services are like below;

How can I solve this issue?
Thanks!

In your metricbeat-daemonset-modules ConfigMap, there are two modules defined: system and kubernetes. Similarly you will need to define the elasticsearch module. Remember to set xpack.enabled: true in this module's configuration!

Hi Shaunak,
I'm new at ES and Kubernetes so I'm not sure how to do it.
Whole "metricbeat-daemonset-modules" file is below(output of kubectl edit configmap metricbeat-daemonset-modules)

To where should I paste "xpack.enabled: true"?

Hi Again,
Regarding to my env (pods and services) above, what should I put for "HOST" and "PORT" variables on metricbeat.yaml?
