rabbitmq logs in json format.

[maha...@gmail.com]

Hi:

Is there a way to get rabbitmq log messages in json format ? I am using version 3.7.4

Thanks

Maha

Hi Maha,

Log messages in JSON is not supported. Thanks for asking on the mailing list, however, and continue to use this resource if you have further questions.

Thanks Luke! I am trying to use advanced.config with lager_json_formatter(https://github.com/botsunit/lager_json_formatter) . Is there a doc or how-to for building the formatters and how to add them to rabbitmq deployment ?

Hi Maha -

This question was asked earlier this year, and here is my reply - https://groups.google.com/d/msg/rabbitmq-users/KmjRYB78ROw/LT5TyAgDBwAJ

Let me know if you need assistance. What operating system are you using?

Thanks -

Luke

I am working with the publicly available docker images - either alpine or debian. Is it still the same process?

Yes, though the configuration file is /etc/rabbitmq/advanced.config

When you install Erlang, it will install a compiler. You should just need to install git or extract the source code to the lager_json_formatter plugin, then run this command:

./rebar3 compile

That will produce a .beam file in _build/default/lib/lager_json_formatter/ebin/

You then copy lager_json_formatter.beam to a directory in the code path for RabbitMQ:

rabbitmqctl eval 'code:get_path().'

This produces a lot of output on my Ubuntu 16 VM, but the first directory is what you want:

/usr/lib/rabbitmq/lib/rabbitmq_server-3.7.5-beta.3/ebin

The directory will be different in your installation, but that's where you copy the beam file.

After configuring lager correctly and re-starting RabbitMQ, you should have logs in JSON format.

Let me know how it goes,

Luke

Hi Luke, this post helped me a lot but now that lagger is under the hood of Rabbitmq is it possible to have the output reformatted in JSON without using the lager_json_formater ? 

[Luke Bakken]

Hello,

lager_json_formater is required to output JSON.

We can investigate shipping this plugin with RabbitMQ, but I can't promise that it will be included. If you have problems building and installing lager_json_formater please post a new message to this group with information.

Thanks,

Luke

Thanks Luke for the clarification , the thing is that i'm deploying rabbitmq in a kubernetes cluster and i would prefere not to build my own images  with some extra plugins etc. 

[Luke Bakken]

Hi Nikolay,

Noted. I'll bring this up with the RabbitMQ team this week.

Thanks,

Luke

We've concluded that we won't be including Lager JSON formatter because we would not want to maintain it,

and once you depend on something, that dependency's problems become your problems eventually.

Thanks Michael for the update, do you foresee a built-in method for outputting the logs in json ?

If we wanted to add such feature using the JSON Lager output would be the easiest option.
