Is there a reason you made this a metric on it's own? Can we just include this in the metadata of "app_walkthroughSelectTemplate"?

[roger-zhangg]

This is a metadata. We need to define metadata in order to use them in metrics.

[seshubaws]

I mean, can we not say inside of the "app_walkthroughSelectTemplate" metric

"metadata": [
                {
                    "type": "template",
                    "required": true
                },

and have the value of "template": "s3_resizing" / "rest_api_hello_world" or something like that?

For all of these metrics, can we add a metadata with "section: app_playground"? We want to add this metadata to the already existing metrics as well (when we implement them in the new code we write) so that we can easily compile all the metrics related to app playground in one dashboard.

[roger-zhangg]

Do you mean add a metadata to existing metrcis to indicate it's emitted by our fucntion? So the metadata name will be section and value could be empty or app_playground ?
