Failed to enable plugin "prometheus_process_collector": it may have been built with an incompatible (more recent?) version of Erlang

[jperville]

I am building a custom rabbitmq docker images (based on the official rabbitmq 3.6.12 image) that includes this collector. The image builds successfully but running it fails with the following message:

Failed to enable plugin "prometheus_process_collector": it may have been built with an incompatible (more recent?) version of Erlang

Would it be possible to release new binaries of this plugin that are compatible with the current version of the official rabbitmq:3.6.12 docker image? Thank you very much.

Here is the Dockerfile I used:

$ cat Dockerfile
FROM rabbitmq:3.6.12

Hi,

I recently rebuilt everything with R16B03 - https://github.com/deadtrickster/prometheus_rabbitmq_exporter/releases/tag/rabbitmq-3.6.12-pre18. I also modified Dockerfile to include local copies of the plugins as I always forgot to update the links :-)

Please let me know

[jperville]

I will try it up and report my success ASAP.

The rabbitmq-3.6.12-pre18 release works for me, closing this issue. Thank you @deadtrickster.
