> PrometheusPushGatewayReporter support filter label keys
> -------------------------------------------------------
>
> Key: FLINK-24891
> URL: https://issues.apache.org/jira/browse/FLINK-24891
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / Metrics
> Affects Versions: 1.14.0
> Reporter: Echo Lee
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.15.0
>
>
> Sometimes, we don’t care some label keys, such as host, tm_id, etc. At the
> same time, we can make the label very short.
> So we need to support filtering some labels, such as the introduction of
> similar *filterLabelKeys* parameters, the value can be multiple, separated by
> semicolons, For example,
> configuration.setString("metrics.reporter.promgateway.filterLabelKeys",
> "host;tm_id;task_attempt_id;job_id;job_name")
>
> Before adding parameters:
> {+}host{+}{*}={*}"" instance="" job="task_test3"
> {+}job_id{+}{*}={*}"4dc230ce97e6bebd559d96956ca21e2e"
> {+}job_name{+}{*}={*}"insert_into_default_catalog_default_database_print"
> subtask_index="2"
> {+}task_attempt_id{+}{*}={*}"92b5b1dba2679749d56aa298cd3b35d5"
> task_attempt_num="0" task_id="cbc357ccb763df2852fee8c4fc7d55f2"
