How can we verify this configuration management.http.max_body_size in rabbitmq ?

[sakshiag]

We are trying to set new configuration management.http.max_body_size according to rabbitmq/rabbitmq-server#9708

Erlang Verison : 26.2.3

Rabbitmq Version : 3.13.1

How can we verify if it is using the set value ?

 Can you please help us with this?

That PR was released for v3.12.x in https://github.com/rabbitmq/rabbitmq-server/releases/tag/v3.12.7 (see #9709). You'll need to upgrade v3.12.7 for that limit to take effect.

By "3.12.7" you mean "to the latest 3.12.x or 3.13.x" ;)

You can simply try it. If a certain configuration key is not supported by the version you are running, the node will fail to start and will report that the configuration key is not known.

You should move to 3.13.x, by the way, in order to have community support now.

I am sorry I mentioned the version incorrect. We are trying to add this configuration for 3.13.x. i will correct it in the description also

RABBITMQ_CONFIG_FILE=./management.http.max_body_size.conf sbin/rabbitmq-server

works just fine for me with the following rabbitmq.conf:

management.http.max_body_size = 10000000

The docs have a dedicated section on how to verify effective configuration:

rabbitmq-diagnostics environment | grep body
# =>      {max_http_body_size,10000000},
