-------------------------------------
Summary: Heatmap memory should not include cached memory as part
of "used"
Key: AMBARI-1946
URL: https://issues.apache.org/jira/browse/AMBARI-1946
Project: Ambari
Issue Type: Bug
Components: client
Affects Versions: 1.2.2
Reporter: Jeff Sposetti
The "Memory Used %" is currently calculated using thie forumla:
(mem_total - mem_free)/mem_total
Although this is accurate, the total includes mem_cached (file system cache),
which the kernal can take back whenever it wants to.
Therefore, formula can be doing this instead:
(mem_total - mem_free - mem_cached)/mem_total
