----------------------------------
Summary: PrometheusServlet does not work well with queryName in
the metric name
Key: SPARK-48223
URL: https://issues.apache.org/jira/browse/SPARK-48223
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 3.4.3, 3.3.4, 3.5.1
Reporter: Mason Chen
PrometheusServlet does not work well with queryName in the metric name.
For driver metrics, the configuration `spark.metrics.namespace` allows the user
to remove the app id from the metric name to build reusable dashboards and
metric queries in external systems.
Similarly, we need a feature to replace the query name in the spark streaming
metric names to make dashboards and metric queries reusable. Ideally, the query
name would be generated as a tag, instead of part of the metric name.
