             Summary: UI Improvements For Server Side Alerts
                 Key: AMBARI-10625
                 URL: https://issues.apache.org/jira/browse/AMBARI-10625
             Project: Ambari
          Issue Type: Task
          Components: ambari-web
    Affects Versions: 2.1.0
            Reporter: Antonenko Alexander
            Assignee: Antonenko Alexander
             Fix For: 2.1.0


https://issues.apache.org/jira/browse/AMBARI-10348 adds a new type of alert known as a server-side alert. These are used to run specialized classes inside of the Ambari JVM which can produce alerts without the need to run them on an agent. We currently use this for 2 types of alerts:

- If a host goes down
- If alerts have not run within 2x their normal interval values

This new alert causes some display weirdness in the UI (see attachment). Seems like we need a new UI asset to assign as the icon for this new type of alert.

As for alert properties, there's only 1 property right now which is the classname. Similar to script alerts, we can choose not to expose this value since nobody really should be changing it anyway.

For fun, here's the JSON:

{code:title=Server Alert Definition JSON}
  "AlertDefinition" : {
    "cluster_name" : "c1",
    "component_name" : "AMBARI_SERVER",
    "description" : "This alert is triggered if the server has lost contain with an agent.",
    "enabled" : true,
    "id" : 80,
    "ignore_host" : false,
    "interval" : 1,
    "label" : "Ambari Agent Heartbeat",
    "name" : "ambari_server_agent_heartbeat",
    "scope" : "HOST",
    "service_name" : "AMBARI",
    "source" : {
      "class" : "org.apache.ambari.server.alerts.AgentHeartbeatAlertRunnable",
      "type" : "SERVER"
    }
  }
{code}
