Hi I've reinstalled my rabbitmq server, hence reinstalled the plugin

Apologies for the disruption, elixir and <code class=

The package has been built using Erlang 24, the error: <div class="snippet-clipboa

This is the error with RabbitMQ 3.8.19 <div class="snippet-clipboard-content notra

I start getting a grasp of what might be happening in here.

ex_aws claims in their README the default JSON decoder is Poison:
https://github.com/ex-aws/ex_aws/blob/b40c33e55ace5820d20888ba2a27c5922daba233/README.md#json-codec-configuration
Yet in their defaults they set Jason (changed 2 years ago):
https://github.com/ex-aws/ex_aws/blob/554465b8783b903ed831e518f463fb2878d6f50e/lib/ex_aws/config/defaults.ex#L10

In mix, they set Jason as an optional dependency:
https://github.com/ex-aws/ex_aws/blob/master/mix.exs#L40

When the plugin is built, Jason is not downloaded (Poison is instead as it's a dependency of the Plugin) and therefore not included in the release. I will replace Poison with Jason and make a fix on ex_aws.

I still need to verify why it works in Docker but I suspect it's because Jason is installed in there as native library.

Apologies for the disruption, elixir and logger dependencies were updated too.

Please let me know if the issue persists.

The package has been built using Erlang 24, the error:

This BEAM file was compiled for a later version of the run-time system than 23.

Suggests you are using erlang <= 23. Are you sure your system is running Erlang 24?

I noticed it might take some time between AWS receives the metrics and it renders it. I would recommend you to wait half an hour before checking if new metrics are in.

Also please note that Debian Erlang packages are a bit challenging to handle as they split all dependencies into separate packages. Moreover, they tend to be always a bit out-of-date.

RabbitMQ recommends different sources for Erlang packages. I usually use those from Erlang Solutions. They package the whole eco-system into a single .deb which makes it easier to get your environment correctly configured.

I've deleted my today's post as I was doing actions on the wrong instance, inviting you to delete yours too to clear out this issue for search purpose, and sorry about that :)
Back to the pb, I did update both dependencies logger and elixir but still having this log :

Here is how I tested the plugin with a Dockerfile.

Browse to http://localhost:15672 login with default credential. I created few queues and published few messages. I could see the metrics in AWS CW. No error logs, just a warning:

Problem reading some plugins: [{"/opt/rabbitmq/plugins/lager-3.8.0.ez",
                                duplicate_plugin}]

I cannot remove lager as a package as in some old deployment it was giving me some issues.

Hi guys, tomorrow I'm going to try this plugin with RabbitMQ 3.9.1 and Erlang 24 in an EC2 instance.
Today I successfully installed this plugin retrieving packages of the latest version (1.0.0) via GitHub API, in a Docker container (RabbitMQ 3.9.1 and Erlang 24)... without trying metric creation in CloudWatch, though 😅.

Maybe useful, GitHub API call:

curl -H "Accept: application/vnd.github.v3+json" https://api.github.com/repos/noxdafox/rabbitmq-cloudwatch-exporter/releases | jq ".[0].assets[].browser_download_url"

@noxdafox @falcocoris same issue for me and no metric on CloudWatch. EC2 instance with Ubuntu18.04, RabbitMQ 3.9.1 and Erlang 24.0.5.
Asap I'm going to try installing the RabbitMQ 3.8.X.

Release updated, Poison replaced with Jason. Tested locally and on a Docker container and it seems to be working.

Could you please confirm the fix?

falcocoris commented on July 18, 2024

I confirm the fix !
Thx for your work mate, I'll close this up :)

Sonic0 commented on July 18, 2024

Yes, I confirm too! Both RabbitMQ versions (3.8.x and 3.9.1) work! Thanks @noxdafox
