Subject [jira] [Commented] (AMBARI-7808) Service pluggability: metrics graphs to show in Ambari Web's service pages should be declared in the stack definition

Yusaku Sako commented on AMBARI-7808:
-------------------------------------

[~jaoki]
This JIRA is not intended for generically migrating all hard-coded configs in Ambari Web to
the stack definition (though we should have a separate JIRA for that).
The scope of this particular JIRA should be to move service metrics graph metadata that is
hard-coded in Ambari Web to the stack definition.  I.e., we should remove service_graph_config.js
created in AMBARI-7601 and make it part of the stack definition.
In addition, I think we should think about how we could represent service graphs in the stack
definition so that we can remove App.ChartServiceMetrics* classes in Ambari Web (see ambari-web/app/views/main/service/info/metrics/<service-name>).
 This way, we can easily define new graphs for new/existing services by editing the stack
definition and not Ambari Web code.

> Currently, which metrics graphs to display in Ambari Web's service pages is hardcoded
in ambari-web code.
> We should make it such that 1) the graphs to display are declared in the stack definition
for each service and 2) ambari-web code needs to load this information and display appropriate
graphs under the service page.
