[jira] [Created] (KAFKA-9977) Kafka Connect Task level error metrics exposed via JMX not removed on connector delete

Tharindu created KAFKA-9977:
-------------------------------

             Summary: Kafka Connect Task level error metrics exposed via JMX not removed on connector delete
                 Key: KAFKA-9977
                 URL: https://issues.apache.org/jira/browse/KAFKA-9977
             Project: Kafka
          Issue Type: Bug
          Components: KafkaConnect
    Affects Versions: 2.3.1
            Reporter: Tharindu


When collecting metrics at a task level exposed via JMX it was noticed that task level metrics reported under 

*_kafka.connect:type=task-error-metrics,connector="\{connector}",task="\{task}"_*

were not being removed on connector deletion resulting in us collecting metrics for tasks no longer active. 

In the source code I could not find a point where these metrics were cleaned up.
