How do I view the "Extended metrics" for a Node.js App in Application Insights

I have installed the applicationinsights-native-metrics package mentioned here: https://learn.microsoft.com/en-us/azure/azure-monitor/app/nodejs

I assume my app is generating metrics mentioned in the article but I can't quite figure out how to view them in Application Insights. Any pointers would be greatly appreciated.

    The trick was to use a version of applicationinsights package, specifically 2.9.5. Using a 3.x.x version did not communicate the metrics correctly to the Metrics Explorer in Monitoring > Metrics.

    Thanks for posting your question in the Microsoft Q&A forum.

    Follow these steps:

    In the Azure portal, navigate to your Application Insights resource. under the Investigate section, select Metrics Explorer. in the Metrics Explorer, click on the Add metric button. This will open a panel on the right side. in the panel, expand the Node.js Extended Metrics namespace to see the available extended metrics. You should see metrics like % CPU Time in GC, Event Loop Ticks, Heap Used, and Non-Heap Used. Select the metrics you want to view by clicking on the checkbox next to each metric name
