Solr metrics do not display any data

We have a SolrCloud service in Kerberos security enabled CDH 6 cluster. There a lot of collection in SolrCloud and Metric monitoring configuration is enabled, but there are NO DATA in all charts and collection name is not displaying under Collections dropdown in Collection Statistics tab.

How do we fix this situation?

Even I have the same issue, I have deployed a few charts for solr replica and solr server metrics from cloudera documentation.

I've opened a ticket to Cloudera and they have asked me to upgrade from 6.1 to 6.2 mentioning the key error as 'gc.ConcurrentMarkSweep.count' and will be fixed in 6.2.

But after the CM upgrade, I still can't see the charts showing the data, and new error started showing in the cloudera-scm agent logs.

here is the error

[20/May/2019 18:11:54 +0000] 90913 Monitor-HostMonitor throttling_logger ERROR Timed out waiting for worker process collecting filesystem usage to complete.

I found the problem. The problem is about ssl certificates, we use custom ssl certificate and agents couldn't recognize it and fired the exception. I import ssl certicate to keystore and the problem is solved.
