[jira] [Commented] (AMBARI-20391) Ambari Metrics Grafana Datasource plugin does not work when configured with a reverse proxy with subpath

["Yusaku Sako (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMBARI-20391?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15904306#comment-15904306 ] 

Yusaku Sako commented on AMBARI-20391:
--------------------------------------

https://github.com/grafana/grafana/blob/v2.6.0/public/app/core/services/backend_srv.js#L68-L70 was adding extra subpath even though the URL already contains it.  The fix was to use the backendSrv.datasourceRequest, and not use backendSrv.get directly.

> When Grafana is set up with a reverse proxy with sub path (http://docs.grafana.org/installation/behind_proxy/), Ambari Metrics datasource plugin does not work.
> With the subpath "/grafana", Grafana is making calls with incorrect URLs to the Metrics Collector.
