----------------------------------
Summary: Prometheus metrics reporter doesn't respect
`metrics.scope`
Key: FLINK-9898
URL: https://issues.apache.org/jira/browse/FLINK-9898
Project: Flink
Issue Type: Bug
Components: Metrics
Affects Versions: 1.5.1, 1.4.2, 1.4.1, 1.5.0, 1.4.0
Reporter: Prithvi Raj
The Apache Flink
[documentation|https://ci.apache.org/projects/flink/flink-docs-release-1.5/monitoring/metrics.html#system-scope]
details that users may change the default scope of metrics emitted by using a
scope format.
Changing the scope format allows end users to store metrics with lower
cardinality while introducing the drawback of being unable to differentiate
between metrics from different tasks/operators/etc sharing the same name.
With the Prometheus reporter, regardless of the scope format used, every
variable is always emitted.
Would it be reasonable for the Prometheus reporter to respect the scope format
and only emit dimensions that are in scope?
