> As a part of this ticket, create an experimental flag under which poll for
> the widget information from the stack while landing on the service summary
> page for the first time. Since this is a static information, it is required
> to be polled just once. This needs to be mapped to a model as described below
> Example API for HDFS service:
> {code}
> {
> href:
> "http://c6401.ambari.apache.org:8080/api/v1/stacks/HDP/2.2/services/HDFS/artifacts/widget_layout";,
> Artifacts: {
> artifact_name: "widget_order",
> service_name: "HDFS",
> stack_name: "HDP",
> stack_version: "2.2"
> },
> artifact_data: {
> name: "HDFS", // This is the serviceName in the ember-data model
> sections: [
> {
> name: "HDFS_SUMMARY" // This is the sectionName as described in
> the below ember-data model
> widgets: [
> {
> widget_name: “NAMENODE_HEAP”,
> widget_type: “GAUGE”,
> component_name: “NAMENODE”,
> display_name: "NameNode Heap",
> expression: [{
> template: “${jvmMemoryHeapUsed}/${jvmMemoryHeapMax}”
> }],
> properties: {
> “warning_threshold”: 0.5,
> “error_threshold”: 0.7
> }
> },
