             Summary: [Ambari metrics][grafana] grafana is not showing any datapoints if the queue name contains special characters
                 Key: AMBARI-24403
                 URL: https://issues.apache.org/jira/browse/AMBARI-24403
             Project: Ambari
          Issue Type: Bug
            Reporter: Akhil S Naik


grafana is not showing any data points if the queue name contains special characters

I have a queue named 'A&B' , in Yarn queues dashboard if I select this queue name I am getting empty data showing no data points.

The issue is reproducible

Analysis : 

In grafana UI we are sending the request to fetch the data by encoding the URI.
for which the server is interpreting it as separate parameters 

http://mygrafanaserver.com:3000/api/datasources/proxy/1/ws/v1/timeline/metrics?metricNames=yarn.QueueMetrics.Queue=root.{color:red}A&B{color}.AppsRunning._max&appId=resourcemanager&startTime=1533181180&endTime=1533202780

Which should ideally be :

http://mygrafanaserver.com:3000/api/datasources/proxy/1/ws/v1/timeline/metrics?metricNames=yarn.QueueMetrics.Queue=root.{color:red}a%26b{color}.AppsRunning._max&appId=resourcemanager
