Description

There is a type of alert known as a "SERVER" alert which is a Java class that runs inside of the Ambari Server. We use these alerts to check for specific issues with the Ambari Server itself.
However, nothing should prevent a cluster's services from being able to define one of these. Consider the following case where we want a new server-side alert to run for the ZooKeeper Service which checks something specific that none of the agent-side alerts are appropriate for:

{
  "ZOOKEEPER": {
    "service": [
      {
        "name": "Foo",
        "label": "Foo ZK Alert",
        "description": "Foo",
        "interval": 5,
        "scope": "SERVICE",
        "enabled": true,
        "source": {
          "type": "SERVER",
          "class": "org.apache.ambari.server.alerts.ZKFooChecker"
        }
      }
    ],
  ...
