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