Prometheus plugin: :15692/metrics/per-object endpoint gives "Unknown Registry"

[thoma...@gmail.com]

Hello fellow RabbitMQ users,

We are working on getting Prometheus plugin up and running, and encountered the following issue (RabbitMQ 3.8.9 and Erlang 23.1.1):

Scraping the ":15692/metrics" endpoint works well, but when giving the per-object endpoint ":15692/metrics/per-object" I get the following:

$ curl -v -H "Accept:text/plain" "http://localhost:15692/metrics/per-object/"

*   Trying 127.0.0.1...

* Connected to localhost (127.0.0.1) port 15692 (#0)

> GET /metrics/per-object/ HTTP/1.1

> Host: localhost:15692

> User-Agent: curl/7.45.0

> Accept:text/plain

>

< HTTP/1.1 404 Not Found

< content-length: 16

< content-type: text/plain

< date: Mon, 06 Sep 2021 09:38:55 GMT

< server: Cowboy

<

* Connection #0 to host localhost left intact

Unknown Registry

Has anyone seen this? I can get per-object metrics if I set  "rabbitmqctl eval 'application:set_env(rabbitmq_prometheus, return_per_object_metrics, true)."

Best Regards,

Thomas Oliw
