-----------------------------------------
Summary: Create and populate Metrics section of a slider app
Key: AMBARI-5928
URL: https://issues.apache.org/jira/browse/AMBARI-5928
Project: Ambari
Issue Type: Bug
Components: client
Affects Versions: 1.6.1
Reporter: Oleg Nechiporenko
Assignee: Oleg Nechiporenko
Fix For: 1.6.1
A running slider app should show the metrics section (hidden otherwise). The
metrics section should be populated by graphs which should be laid out 4 per
row.
The way to determine the metric names for a running app is to look at the
"metrics" property in response.

Each of the key in the "metrics" property becomes a graph.
The way to get time-series information for that graph is by calling
{{api/v1/views/SLIDER/versions/1.0.0/instances/SLIDER_1/apps/app1/metrics/jvm/memNonHeapUsedM}}
- which should provide the same time-series data as all the other graphs in
Ambari.
