@abhishekagarwal87 Yeah I think you're right. It's time-series DB specific
restriction. Thanks for reminding me.

> We're exposing metrics to metrics consumer, and most of them are storing
> metrics to time-series DB.
> Well-known common rule of generating metric name for these DB is using dot
> ('.') to separate parts, so that it can be parsed easily when needed.
> For example, graphite separates part of metric name to dot, and support
> wildcard for each part. Note that it doesn't support wildcard matching
> multiple parts.
> Since topology name or component name having dots are not common case to use
> case of user, I think we can warn users to not having dots on their topology
> name or component name. We can even restrict to not having dots if we all are
> really OK with this.
