just curious is the label key here resource.subscription_id? I understand the value is test-subscription, but not sure whats the resource part. Thanks!

This is more like a property but we thought it was a bit too "complex" to talk about metadata, labels, resources, properties... so we joined all of them into "labels".

This information comes on each response of the Stackdriver API. The one you mention here is a resource label as you can see in the link (follow MonitoredResource link too). You can also find "system" labels, "user" labels and instead of having a bunch of user.labels.*, resource.labels.*, system.labels.* we swapped the .labels part to just have everything under the key labels.*

For example, resource labels in compute are the instance type or the storage type. User labels are a key-value you can set in gcp console.

In this case, PubSub don't have the specific implementation to gather user labels so we are missing the data that the user might input in the console. This data uses PubSub API and not Stackdriver API, that's why each metricset requires an specific implementation inside the stackdriver metricset

I'm not sure if I did a very good job explaining this now, frankly 😅

nit: is this change necessary? 😬

I might mess it up solving the conflicts. Glad that you spot it to take a closer look 😬

I think it was only that, I reverted it 😬
