Thanks for looking into this @harshal619

Few suggestions

• would be better to log the URLs where they are used, i.e. when each component is initialized
• add URLs to log context to be more consistent with other logs like Started REST API server address=http://127.0.0.1:9596
• single line log should be sufficient, could include count as part of context but I don't think it is required as there are usually just 1-3 urls

Possible solution for this unstable...nflaig/log-connected-service-urls

@nflaig Makes sense to log URLs where the component is initialized.
The suggested solution by you looks sufficient.

Anyway, it was a good start for me to look into the code and understand it a little.
should I close this PR? As suggested solution already covers all the required changes.

Solution looks pretty solid overall and is technically correct, just few nuances to better fit into current logging pattern (logs are kinda subjective and not sure I got it quite right either, definitely needs another review)

should I close this PR? As suggested solution already covers all the required changes.

Sure, might make things easier. I will close this one when I open up the other PR.
