i dont think there's an issue with otel exporting metrics. because i tested
its exporting metrics. I tested by stopping oap and started back so its able to
reconnect and successfully export metrics. Please see the logs for reference.
**_Note:_** I enabled logs from **DEBUG** to _INFO_ just for clean
representation. other wise there's no issue in printing metrics
