Alarm states

The class IltAlarmObjectStateSAXInfo is the XML serialization class that allows you to read and write alarm states in the XML format.

The following table describes the XML elements that can be used.

XML elements in the Alarm state system

XML Element	Attributes	Possible Values	Description
`<alarms>`			Delimits alarm state definition
	`notReporting`	`true` or `false`	This is an optional attribute. It defines whether the managed object is currently not reporting its alarm state.
	`lossOfConnectivity`	`true` or `false`	This is an optional attribute. It defines whether the managed object is currently without connectivity.
`<new>`			Structural element that lets you specify new alarms for an object
	`severity`	`Raw.Critical` , `Raw.Major` , `Raw.Minor` , `Raw.Warning` or `Raw.Unknown` `Impact.CriticalHigh` , `Impact.CriticalLow` , `Impact.MajorHigh, Impact.MajorLow` , `Impact.MinorHigh` , `Impact.MinorLow, Impact.WarningHigh, Impact.WarningLow` or `Impact.Unknown`	This attribute is mandatory. It defines the severity of the new alarm to be set.
	`operation`	`set` , `add` , `remove`	This attribute is optional. It specifies whether the alarm should be set, added to or removed from the object state. The default value is `set` indicating that the alarm will be set in the object state. This attribute is used within an `<updateState>` element.
`<ack>`			Structural element that lets you specify acknowledged alarms for an object
	`severity`	`Raw.Critical` , `Raw.Major` , `Raw.Minor` , `Raw.Warning` or `Raw.Unknown` `Impact.CriticalHigh` , `Impact.CriticalLow` , `Impact.MajorHigh, Impact.MajorLow` , `Impact.MinorHigh` , `Impact.MinorLow, Impact.WarningHigh, Impact.WarningLow` or `Impact.Unknown`	This attribute is mandatory. It defines the severity of the acknowledged alarm to be set.
	`operation`	`set` , `add` , `remove`	This attribute is optional. It specifies whether the alarm should be set, added to or removed from the object state. The default value is `set` indicating that the alarm will be set in the object state. This attribute is used within an `<updateState>` element.

How to add a network element and a link with alarms defined in XML

<addObject id="NE2">
  <class>ilog.tgo.model.IltNetworkElement</class>
  <attribute name="name">NE2</attribute>
  <attribute name="type">Mainframe</attribute>
  <attribute name="position" javaClass="ilog.cpl.graphic.IlpPoint">
    <x>229</x>  <y>126</y>
  </attribute>
  <attribute name="objectState"
    javaClass="ilog.tgo.model.IltBellcoreObjectState">
    <state>EnabledActive</state>
    <alarms>
      <new severity="Raw.Critical">5</new>
      <ack severity="Impact.WarningLow">2</ack>
    </alarms>
  </attribute>
</addObject>

<addObject id="Link2">
  <class>ilog.tgo.model.IltLink</class>
  <link>  <from>PolyGroup</from>    <to>NE3</to>  </link>
  <attribute name="name">Link2</attribute>
  <attribute name="media">Fiber</attribute>
  <attribute name="objectState" javaClass="ilog.tgo.model.IltSONETObjectState">
    <state>Active</state>
    <alarms notReporting="true" />
  </attribute>
</addObject>

How to set alarms to an existing object using XML

The following example shows how to set alarms to an object that already exists in the data source. You can achieve this by using the XML tag <updateObject> to modify the attribute objectState :

<updateObject id="NE1">
  <attribute name="objectState" javaClass="ilog.tgo.model.IltOSIObjectState">
    <state>
      <operational>Disabled</operational>
      <usage>Idle</usage>
      <administrative>Unlocked</administrative>
    </state>
    <alarms>
      <new severity="Raw.Critical">2</new>
      <new severity="Raw.Warning">1</new>
      <ack severity="Raw.Minor">3</ack>
    </alarms>
  </attribute>
</updateObject>

How to update alarms incrementally using XML

<updateObject id="NE1">
  <updateState>
    <alarms>
      <new severity="Raw.Critical" operation="remove">1</new>
      <new severity="Raw.Warning" operation="add">1</new>
      <ack severity="Raw.Critical" operation="add">1</ack>
      <ack severity="Raw.Minor" operation="remove">3</ack>
    </alarms>
  </updateState>
</updateObject>
