Enable Object Instance Tracking on a Node

  1. In the left navigation pane, click Tiers & Nodes.
  2. In the Tiers & Nodes panel navigate to and select the node that you want to track.
  3. Double-click or click View Dashboard.
  4. In the node dashboard, click the Memory tab.
  5. Click the Object Instance Tracking subtab.
  6. Click On to start tracking.
    After completing the heap analysis, the agent begins tracking the top 20 object types in the heap.
When you are finished tracking, click Off because tracking can slow down the Node.js process. Use OIT for only for brief periods.
Warning: Although the Node.js OIT UI displays "Class" and "Classes" throughout, the Node.js Agent tracks object types, not classes. Substitute "object" for "class" wherever you see "class" for this feature.
