-------------------------------------
Summary: Create ember data model for widget
Key: AMBARI-10102
URL: https://issues.apache.org/jira/browse/AMBARI-10102
Project: Ambari
Issue Type: Task
Components: ambari-web
Affects Versions: 2.1.0
Reporter: Andrii Tkach
Assignee: Andrii Tkach
Fix For: 2.1.0
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
}
},
{
widget_name: "HDFS_BYTES_READ",
widget_type: “HEATMAP”,
display_name: "HDFS Bytes Read",
description: "",
component_name: “DATANODE”,
expression: [
{
template: "${metrics.dfs.datanode.bytes_read}"
}
]
properties: {
display_unit: "MB",
max_limit: "1024"
}
}
]
}
]
},
]
}
]
}
}
{code}
{code}
App.Widget = DS.Model.extend({
widgetName: DS.attr('string'),
defaultOrder: "" // This field is not derived from API but needs to be filled
in the mapper on the client side
widgetType: DS.attr('string'),
displayName: DS.attr('string'),
serviceName: DS.attr('string'),
componentName: DS.attr('string'),
timeCreated: DS.attr('number'),
sectionName: DS.attr('string'),
author: DS.attr('string'),
properties: DS.attr('object'),
expression: DS.attr('array')
});
{code}
