Switch from labels to tags

[rittneje]

Apparently New Relic has dropped support for APM labels, in favor of tags. https://forum.newrelic.com/s/hubtopic/aAX8W0000008ctsWAA/important-upcoming-changes-to-capabilities-and-support-across-errors-classic

However, the Go agent only supports labels, and continues to create them. This has led to complications for us, since labels have to manually deleted, and the Rest API for doing so is unsupported and buggy.

Please change the implementation of the Go agent to report labels as tags.

From what I understand, the labels the agent sends are converted into tags by New Relic's backend. What issues are you experiencing? Can you verify that you are seeing labels and not tags being generated from your APM agent?

@iamemilio We are seeing both. They seem to show up as normal tags in the UI, but also get reported as labels by the rest API.

Gotcha, I understand the confusion. It would be nice for the agent so send tags for consistency, but that would probably have to be a cross agent initiative. None of the agents send tags at the moment. All APM agents send labels to New Relic, then they get transformed into tags as part of the ingestion pipeline which is probably where the confusion is coming from.
