Github user ptgoetz commented on the issue: https://github.com/apache/storm/pull/2203 @revans2 Thanks for clarifying. I have a better understanding of what you're saying now. How do you feel about just replacing "." with "_" on all metrics path components (host name, componentId, etc.)? That would ensure a path could be reliably split on the "." character. I'll add stream id and executor id to the path in places where they are available.
