             Summary: Show warning message when dot ('.') is used for topology name or component name
                 Key: STORM-1965
                 URL: https://issues.apache.org/jira/browse/STORM-1965
             Project: Apache Storm
          Issue Type: Improvement
          Components: storm-core
            Reporter: Jungtaek Lim
            Assignee: Jungtaek Lim
            Priority: Minor


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.
