(Optional) Add the <ReconfigDetectionAttr> Section

You can detect metric family changes using a dedicated scalar attribute in the metric family. This method is more efficient than add the <componentReconciliation> section; it performs better and generates much less network traffic. Only the scalar attribute is polled to determine if there is a change.

If a metric family has a scalar attribute to detect a change, you can specify that scalar attribute in the <ReconfigDetectionAttr> section.

Example: Configure Change Detection in the Interface Metric Family

1. Specify the change detection tag, <ReconfigDetectionAttr> to watch the PortReconfig attribute for change:

   <ReconfigDetectionAttr>
   

    {http://im.ca.com/normalizer}NormalizedPortInfo.PortReconfig
   

   </ReconfigDetectionAttr>
