弹性搜索作为 grafana 数据源

Question

Issue: Not able to get data flow from Elasticsearch to Grafana.

I can able to connect to ES Kibana from browser to URL with basic auth (user id & password).

When I hit save and test in Grafana Datasource, I don't see any errors. But, I don't see any data showing up in my grafana panel.

Datasource properties:

URL : http://example.com:5601 
Access: Browser
Auth: Basic Auth
Index name: same name what I used in Kibana query
Grafana Version: 7.0+
Time field name: @timestamp
Level field name: <blank>

I enabled CORS on ES.

Appreciate your help

Here is my Datasource configuration.

Answer 1

You are using Grafana Elasticsearch datasource, but your are connecting to Kibana (typical port 5601) and not to Elasticsearch. Kibana is similar to Grafana - both are "user interfaces" for Elasticsearch. Connect datasource directly to Elasticsearch.

Answer 2

The ES URL what is being configured in Grafana should return below json

{
   "name": "dev1234.dev.company.com",
   "cluster_name": "elasticsearch_es7test",
   "cluster_uuid": "V-QwB6jmSRCtMaMTTYW1qA",
