How to enable GoSDK metrics?

Hi folks

I tried this sample samples-go/metrics at main · temporalio/samples-go · GitHub . Although this created custom metrics, it didn’t spit out the metrics from Go-SDK ( sdk-go/constants.go at master · temporalio/sdk-go · GitHub ).
How do i enable SDK metrics?

Thanks

Those metrics are enabled by default, though it a specific metric has not been counted yet (e.g. a failure metric), it may not appear in the output. That sample should show several Temporal metrics in addition to the custom metrics added in that example. They may not appear to obviously be Temporal metrics because the code in the worker explicitly sets a custom prefix of temporal_samples to demonstrate that setting in the sample.
