------------------------------------
Summary: [Kafka connect] connectors, tasks metrics doubled
Key: KAFKA-10172
URL: https://issues.apache.org/jira/browse/KAFKA-10172
Project: Kafka
Issue Type: Bug
Components: KafkaConnect
Affects Versions: 2.3.1
Reporter: Viktor Utkin
Attachments: image-2020-06-16-12-42-47-753.png
After re-balance of connect cluster (4 nodes in total) we noticed that
* kafka_connect_connect_worker_metrics_task_count
* kafka_connect_connect_worker_metrics_connector_count
are doubled (2x,3x,4x,etc.), so connect show wrong values.
!image-2020-06-16-12-42-47-753.png|width=481,height=240!
But when we request number of connector via RESP API it shows only 36:
{code:java}
› curl -s 127.0.0.1:8083/connectors | jq '.[]' | sort | wc -l
36{code}
