https://issues.apache.org/jira/browse/AMBARI-18511

My Ambari version is Apache Ambari Version2.4.0.1

[#2]

Is there a workaround?

[#3 · Accepted solution]

@Huahua Wei Please login into the Grafana as admin, then go to Datasources and test connection. If that fails, instead of Ambari metrics collector hostname, try adding IP and see if you face the same issue.

Tested,got

HTTP Error Internal Server Error

Then changed to ip address. connection is ok now

And it is normal now
