New Relic Markers clarification on timelines

[pragmaticivan]

Hi, what's the expected behavior for Markers?

Ideally, they should have a beginning/start/completion and failure but you can only register that once.

For a rollout/canary deployment, when should you send the request to the new relic? Before you start the deployment or after? if you do it before, it's more likely any error behavior will be correlated with the beginning of the rollout, but if I do it after, it might not be very clear, especially on long canary deployments.
