I have an envoy, metricbeat and elasticsearch container in my kubernetes cluster. I want to use the envoyproxy module of metricbeat to collect stats and send it to elasticsearch. Configured the module according this page: https://www.elastic.co/guide/en/beats/metricbeat/current/metricbeat-module-envoyproxy.html
The endpoint is available from metricbeat pod (tried with curl command from the pod, gave a valid response), but it seems that the module cannot pick up and transmit the data (the documents only contain the default fields, but not the envoyproxy). There is no error log entry, checked all the pods.
Also, I have tried with prometheus module, used the /stats/prometheus path, in this case the data has been collected, but the metricbeat index template does not contain the proper mappings for this case.
Does anyone has a tip, how to configure properly the envoyproxy module?
Documentation tells rather nothing...
(I am using ELK 7.3.1 and envoy 1.11.0 versions)
