Comment 1 for bug 2018952

To reproduce this behaviour I added two dummy notifiers in the sink, and a third one(tcp) which actually works, like this
~~~
      publishers:
          - notifier://172.17.1.121:5666/?driver=amqp&topic=cloud1-metering
          - notifier://172.17.1.122:5667/?driver=amqp&topic=cloud1-metering
          - tcp://127.0.0.1:3060
~~~

Even though the first 2 weren't reachable, metrics were being sent to the tcp publisher. Does such a behaviour blocks messaging publisher only ? It would be helpful if you could provide some more details to reproduce it.

Could you also try out using "max_retry" parameter like
~~~
- notifier://[notifier_ip]:[notifier_port]?topic=[topic]&driver=driver&max_retry=100
~~~
