Hello, I try to use Metricbeat with the autodiscover feature for docker, with following config Metricbeat.yml: ``` output.elasticsearch: hosts: ["elasticsearch:9200"] setup.template.name: "metricbeat" setup.template.settings: index.number_of_shards: 1 index.number_of_replicas: 0 metricbeat.modules: - module: system metricbeat.autodiscover: providers: - type: docker hints.enabled: true ``` Metricbeat is not able to parse docker event. See below what happend when I restarted kibana on docker: ``` 2019-01-14T10:35:24.441Z DEBUG [autodiscover] autodiscover/autodiscover.go:204 Got a stop event: map[stop:true host:172.20.0.3 port:5601 docker:{"container":{"id":"003a4b7b7f24a0633a486785c79aa3d1f7e2627f4f55b3694b5bc3d534fa2a89","image":"docker.elastic.co/kibana/kibana:6.5.4","labels":{"co":{"elastic":{"logs/module":"kibana","metrics/module":"kibana"}},"license":"Elastic License","org":{"label-schema":{"build-date":"20181205","license":"GPLv2","name":"kibana","schema-version":"1.0","url":"https://www.elastic.co/products/kibana","vcs-url":"https://github.com/elastic/kibana-docker","vendor":"Elastic","version":"6.5.4"}}},"name":"kibana"}} meta:{"docker":{"container":{"id":"003a4b7b7f24a0633a486785c79aa3d1f7e2627f4f55b3694b5bc3d534fa2a89","image":"docker.elastic.co/kibana/kibana:6.5.4","labels":{"co":{"elastic":{"logs/module":"kibana","metrics/module":"kibana"}},"license":"Elastic License","org":{"label-schema":{"build-date":"20181205","license":"GPLv2","name":"kibana","schema-version":"1.0","url":"https://www.elastic.co/products/kibana","vcs-url":"https://github.com/elastic/kibana-docker","vendor":"Elastic","version":"6.5.4"}}},"name":"kibana"}}} config:[0xc420bcbc80]], generated configs: [0xc420bcbc80] 2019-01-14T10:35:24.441Z DEBUG [autodiscover] autodiscover/autodiscover.go:214 Config &{{ } 0xc4205bf120} is not running 2019-01-14T10:35:24.971Z DEBUG [autodiscover] autodiscover/autodiscover.go:162 Got a start event: map[start:true host:172.20.0.3 port:5601 docker:{"container":{"id":"003a4b7b7f24a0633a486785c79aa3d1f7e2627f4f55b3694b5bc3d534fa2a89","image":"docker.elastic.co/kibana/kibana:6.5.4","labels":{"co":{"elastic":{"logs/module":"kibana","metrics/module":"kibana"}},"license":"Elastic License","org":{"label-schema":{"build-date":"20181205","license":"GPLv2","name":"kibana","schema-version":"1.0","url":"https://www.elastic.co/products/kibana","vcs-url":"https://github.com/elastic/kibana-docker","vendor":"Elastic","version":"6.5.4"}}},"name":"kibana"}} meta:{"docker":{"container":{"id":"003a4b7b7f24a0633a486785c79aa3d1f7e2627f4f55b3694b5bc3d534fa2a89","image":"docker.elastic.co/kibana/kibana:6.5.4","labels":{"co":{"elastic":{"logs/module":"kibana","metrics/module":"kibana"}},"license":"Elastic License","org":{"label-schema":{"build-date":"20181205","license":"GPLv2","name":"kibana","schema-version":"1.0","url":"https://www.elastic.co/products/kibana","vcs-url":"https://github.com/elastic/kibana-docker","vendor":"Elastic","version":"6.5.4"}}},"name":"kibana"}}} config:[0xc420b2a750]], generated configs: [0xc420b2a750] 2019-01-14T10:35:24.971Z DEBUG [autodiscover] autodiscover/autodiscover.go:235 Got a meta field in the event 2019-01-14T10:35:24.971Z DEBUG [autodiscover] autodiscover/autodiscover.go:174 Check failed for config &{{ } 0xc4205d2ba0}: 1 error: host parsing failed for kibana-status: error parsing URL: empty host, won't start runner ``` Metricbeat is not able to parse the host, however, the host field is there in the start event.

Hi @ncasaux, Your configuration looks correct, can you please share the labels you are adding to the container you want to monitor? It looks like `co.elastic.metrics/hosts` is missing, check [https://www.elastic.co/guide/en/beats/metricbeat/current/configuration-autodiscover-hints.html#\_docker\_3](https://www.elastic.co/guide/en/beats/metricbeat/current/configuration-autodiscover-hints.html#_docker_3) for an example. Best regards ---

Hi @exekias, I changed it to ``` docker run --name kibana \ -d --rm \ -p 5601:5601 \ --network=myBridgeNetwork \ --label co.elastic.metrics/module=kibana \ --label co.elastic.metrics/hosts='localhost:${data.port}' \ --label co.elastic.logs/module=kibana \ -e "ELASTICSEARCH_URL=http://elasticsearch:9200" \ -e "SERVER_BASEPATH=/kibana" \ docker.elastic.co/kibana/kibana:6.5.4 ``` and there is no more parsing error. However, as my Kibana is exposed under path `/kibana`, how can I tell Metricbeat tries to query `/kibana/` instead of `/` ? ---

Have you tried by adding the path under the `hosts` variable? If that doesn't work you would need to rely on raw settings input: [https://www.elastic.co/guide/en/beats/metricbeat/current/configuration-autodiscover-hints.html#\_literal\_co\_elastic\_logs\_raw\_literal](https://www.elastic.co/guide/en/beats/metricbeat/current/configuration-autodiscover-hints.html#_literal_co_elastic_logs_raw_literal) ---

Hello @exekias , I managed to go a bit further in my analysis, here the current status: 1- When I run Kibana like this (note that the only activated metricset is **status** ): ``` docker run --name kibana \ -d --rm \ -p 5601:5601 \ --network=myBridgeNetwork \ --label co.elastic.metrics/module=kibana \ --label co.elastic.metrics/hosts='${data.host}:${data.port}' \ --label co.elastic.metrics/metricsets=status \ --label co.elastic.logs/module=kibana \ -e "ELASTICSEARCH_URL=http://elasticsearch:9200" \ -e "SERVER_BASEPATH=/kibana" \ docker.elastic.co/kibana/kibana:6.5.4 ``` there is no problem: ``` 2019-01-18T15:30:57.373Z DEBUG [autodiscover] autodiscover/autodiscover.go:162 Got a start event: map[config:[0xc4207f9e60] start:true host:172.20.0.3 port:5601 docker:{"container":{"id":"0fdbbd78e64d9483159cfb989183da5cb4aea06abd80339cb780306379cb54f0","image":"docker.elastic.co/kibana/kibana:6.5.4","labels":{"co":{"elastic":{"logs/module":"kibana","metrics/hosts":"${data.host}:${data.port}","metrics/metricsets":"status","metrics/module":"kibana"}},"license":"Elastic License","org":{"label-schema":{"build-date":"20181205","license":"GPLv2","name":"kibana","schema-version":"1.0","url":"https://www.elastic.co/products/kibana","vcs-url":"https://github.com/elastic/kibana-docker","vendor":"Elastic","version":"6.5.4"}}},"name":"kibana"}} meta:{"docker":{"container":{"id":"0fdbbd78e64d9483159cfb989183da5cb4aea06abd80339cb780306379cb54f0","image":"docker.elastic.co/kibana/kibana:6.5.4","labels":{"co":{"elastic":{"logs/module":"kibana","metrics/hosts":"${data.host}:${data.port}","metrics/metricsets":"status","metrics/module":"kibana"}},"license":"Elastic License","org":{"label-schema":{"build-date":"20181205","license":"GPLv2","name":"kibana","schema-version":"1.0","url":"https://www.elastic.co/products/kibana","vcs-url":"https://github.com/elastic/kibana-docker","vendor":"Elastic","version":"6.5.4"}}},"name":"kibana"}}}], generated configs: [0xc4207f9e60] 2019-01-18T15:30:57.373Z DEBUG [autodiscover] autodiscover/autodiscover.go:235 Got a meta field in the event 2019-01-18T15:30:57.374Z WARN [cfgwarn] status/status.go:53 BETA: The kibana/status metricset is beta 2019-01-18T15:30:57.374Z DEBUG [autodiscover] cfgfile/list.go:62 Starting reload procedure, current runners: 0 2019-01-18T15:30:57.374Z DEBUG [autodiscover] cfgfile/list.go:80 Start list: 1, Stop list: 0 2019-01-18T15:30:57.374Z WARN [cfgwarn] status/status.go:53 BETA: The kibana/status metricset is beta 2019-01-18T15:30:57.374Z DEBUG [autodiscover] cfgfile/list.go:101 Starting runner: kibana [metricsets=1] ``` 2 -
