rabbitmq_prometheus plugin can not listen to ipv6

[ruben-herold]

hi,

we have a nice running rabbitmq cluster on 3.8.9 with erlang 23.1. The cluster is ipv6 only.
I want enable the prometheus plugin for better monitoring. But the plugin only listen on ipv4.

I tried to add this lines to our config:

{rabbitmq_prometheus,
[
{listener, [{port, 15692}, {ip, "::"}]}
]}
].

This also did not help.

The plugin uses

prometheus.tcp.ip = …

for listener interface configuration. If you absolutely must use the advanced config format, the key is rabbitmq_prometheus.tcp_config.ip, not rabbitmq_prometheus.listener.ip.

It should be no different from any other HTTP-based listener in its capabilities.

thx a lot. Can we improve the documentation? I don't see the rabbitmq_prometheus.tcp_config.ip in any type of documentation I could found.

The docs have been updated.
