Question:

What are the "Duplicate metric name" WARN messages in the VSE log files?

Environment:
All supported DevTest releases.
Answer:

When a virtual service model (VSM) is first deployed it creates its metrics. Whenever the same virtual service is reloaded it tries to create the metric again and logs the "Duplicate metric name" WARN message in VSE log. However, since the metric already exists it uses that for measuring.
