Hello!
Could you add information about how to configure datasource(Prometheus) in docker container(maybe how to configure using docker-compose)? Because the example in documentation doesn't work.

Hi @freesky15. Do you have a response or error codes from when you tried to run the script?

Thanks for your feedback.
I have no errors. I've tried to run the command

docker-compose exec os1 bash -c "/usr/share/opensearch/bin/opensearch-keystore add-file plugins.query.federation.datasources.config /usr/share/opensearch/datasources.json"

in the OpenSearch container.
After that I've tried to seen the available metrics in Opensearch Dashboards in Observability but I haven't seen the metrics.
My datasources.json file:
{ "name" : "my_prometheus", "connector": "prometheus", "properties" : { "prometheus.uri" : "http://prometheus:9090" } }
