Sorry for the basic question.  If I am using an all-purpose clusters in Databricks, it seems to combine all my runs together and execute them within the same Apache Spark application.  There is only one application shown in the Spark UI.   Unrelated runs gets mixed up together in the same Spark UI.  I'm using an all-purpose cluster, not a job cluster.

Normally I send the job runs to this cluster by way of the REST API (jobs api).

How can distinguish and review the list of runs that are currently associated with a given "all-purpose" cluster?  I'd like to be able to at least get a simple list of active runs on a given compute.  There are different runs using different compute, and I haven't found a way to filter the list of runs, based on the related compute cluster.  What am I missing?
