---------------------------------------------
[~swagle] Here is a small patch which fixes the issues. However, please feel
free to guide me if you believe that swap_total needs to be included somewhere
else as well or it was deliberately left out.
Here is the API call output after the patch
http://c6403.ambari.apache.org:6188/ws/v1/timeline/metrics?metricNames=swap_total
{noformat}
{
"metrics": [
{
"timestamp": 1452757699114,
"metricname": "swap_total",
"appid": "HOST",
"starttime": 1452757699114,
"metrics": {
"1452757699114": 5767152
}
}
]
}
{noformat}
Snapshot from Ambari Metrics Widgets attached as well. Will be raising a review
board request as well for the same.

> swap_total metric is defined in metrics.json for several services, but it
> appears that the value for this metric is never extracted from the host, thus
> it is not available for consumption by collector and is not returned by API
> calls.
