Review request for Ambari, Andrii Tkach, Dmytro Sen, Jaimin Jetly, Sumit
Mohanty, Sid Wagle, and Yusaku Sako.
Bugs: AMBARI-15892
https://issues.apache.org/jira/browse/AMBARI-15892
Repository: ambari
Description
-------
Issue
In the "NameNode HostLoad" graph, the negative values are seen for the computed
metric "Memory Utilization" which goes by the formula :
( mem_total - (mem_free + mem_cache) ) *100 / mem_total
Bug
AMBARI-15448 changed the way memory metrics are being reported to AMS. This
lead to a double subtraction of mem_cached, thereby leading to a negative value
intermittently.
Fix
Change the widget to :
( mem_total - mem_free ) *100 / mem_total
