Additionally, you may consider the following:
Add a “XXX DEPR” temporary dashboard in your monitoring tool (e.g. New Relic).
Use this to track the DEPR progress throughout, and delete it when you are done.
Monitoring custom metrics has typically been good enough, but there is some sampling.
If you need to be more certain, you can follow similar patterns, but use logging instead.
