Unable to view OS Host information in the Ambari Dashboard(No data Available)

On the Ambari dashboard, the memory usage, Network Usage, CPU usage and Cluster Load information are missing.The dashboard displays the following error:

No data Available

Root Cause :
This issue occurs when there are some temporary files present in the AMS collector folder.

Solution: 

You need to stop ams service vi ambari and then remove all temp files.

mv /var/lib/ambari-metrics-collector /tmp/ambari-metrics-collector_OLD

Now you can restart ams service again and now you should be good with Ambari dashboard, the memory usage, Network Usage, CPU usage and Cluster Load information.
