>             Project: Ignite
>          Issue Type: Bug
>            Reporter: Nusrat Shakarov
>            Priority: Major
>              Labels: ignite-3, metrics
>
> How to reproduce:
> 1. Start cluster
> 2. Configure otlp exporter
> {code:java}
>  cluster config update "ignite.metrics.exporters=[
>      {
>          compression=none
>          endpoint="http://localhost:3001/api";
>          exporterName=otlp
>          headers=[]
>          name="test_exporter"
>          period=5000
>          protocol="http/protobuf"
>      }
>  ]" {code}
> 3. Exporter will start sending metrics. If collector is not configure on port 
> 3001, error logs start appear on the nodes.
> 4. Disable exporter
> {code:java}
> cluster config update "ignite.metrics.exporters.cc_exporter=null" {code}
> 5. No error logs or metrics in collector
> 6. Repeat step 2, to reenable exporter. Metrics/error logs won't appear.
> 7. Restart the nodes. Metrics/error logs will appear.
