----------------------------------------
Summary: Support exclusions for variables
Key: FLINK-15110
URL: https://issues.apache.org/jira/browse/FLINK-15110
Project: Flink
Issue Type: New Feature
Components: Runtime / Metrics
Reporter: Chesnay Schepler
Assignee: Chesnay Schepler
Fix For: 1.10.0
Tag-based reporters export all variables associated with a metric.
This behavior isn't configurable in any way, but may impact performance and
stability. (see FLINK-13418)
I propose to add a new configuration option
{{metrics.reporter.<name>.scope.variables.excludes}} that includes a list of
variables that should be excluded from the return value of
{{MetricGroup#getAllVariables()}}.
This will implicitly cause all tag-based reporter from excluding these
variables completely. In the future we can additionally look into separate
options for controlling whether a variable should be exposed as indexed tags or
not, if the backend supports this distinction.
