Bug report

What Debezium connector do you use and what version?

ibmi connector 3.4.0-SNAPSHOT

What is the connector configuration?

I have two connectors with the same topic.prefix

What is the captured database version and mode of deployment?

DB2 on prem

What behavior do you expect?

When deploying second connector I would like to be able to see the metrics of both

What behavior do you see?

I only see the metrics from the first connector as the metric tags are identical

I also get an exception in the logs javax.management.InstanceAlreadyExistsException source: jrt:/java.management

Do you see the same behaviour using the latest released Debezium version?

Yes 3.4.0-SNASPSHOT

Do you have the connector logs, ideally from start till finish?

can be provided

note this has been reported before https://debezium.zulipchat.com/#narrow/channel/302529-community-general/topic/.E2.9C.94.20MBean.20Unable.20to.20register.20metrics.20on.20connectors/with/506825210

How to reproduce the issue using our tutorial deployment?

create two connectors on the same running instance with the same topic.prefix

Feature request or enhancement

the connector names must be unique

adding the connector name by default into the tags for the metrics would prevent this

Which use case/requirement will be addressed by the proposed feature?

Multiple connectors without manually adding custom metric tags

Implementation ideas (optional)
