-----------------------------------
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.
