If so, all the scripts with the old name must be broken on the existing
platforms. Can we keep both old name and new name for the existing
platforms?
For the event naming, if we want to rename an event. We still keep the
old name and mark it as deprecated in the existing platforms to maintain
compatibility.
Can we do the similar thing for metrics?
For the existing platforms, just add all the metrics from the
perfmon-metrics and don't change the existing metrics unless they have
errors.
Thanks,
