Failing to update few rabbitmq parameters ( Channel Operation Timeout , Consumer Prefetch )

[GitJadhav]

Describe the bug

RabbitMQ Version - 3.12.x
Trying to tune the following parameters running on defaults
1.Channel Operation Timeout
sudo rabbitmqctl environment | grep "channel_operation_timeout"
{channel_operation_timeout,15000},

2.Consumer Prefetch
sudo rabbitmqctl environment | grep "default_consumer_prefetch"
{default_consumer_prefetch,{false,0}},

Reproduction steps

1.Tune Channel Operation Timeout
File - rabbitmq.conf
channel_operation_timeout = 60000
2.Tune consumer prefetch
File - advanced.conf
[
{rabbit, [
{default_consumer_prefetch,{false,250}}
]
}
]
3.rabbitmqctl stop_app , rabbitmqctl start_app
...

Expected behavior

1.Run "rabbitmqctl environment"
2.Confirm the new settings for Channel Operation Timeout and Consumer Prefetch
{channel_operation_timeout,60000}
{default_consumer_prefetch,{false,250}}

Additional context

I am still seeing the defaults and not seeing any tuned settings being applied
Run "rabbitmqctl environment"
{channel_operation_timeout,15000},
{default_consumer_prefetch,{false,0}}

• Please ATTACH the complete configuration files you are using to change these settings.
• Are you certain that RabbitMQ is using your configuration files? It will be logged on RabbitMQ startup.

@lukebakken
Attaching the config files
advanced.conf.json
rabbitmq.conf.json

For logging on RabbitMQ Startup -- Are yo referring to this logs
sudo journalctl -xe
rabbit.log

[michaelklishin]

The correct name of the advanced config file is not advanced.conf, it is advanced.config.

advanced.conf will not be loaded.

I was not even able to start rabbit with advanced.config ..

More than likely the advanced.config file is not formatted correctly, or maybe saved with a UTF-8 BOM.

[lukebakken]

# is NOT the comment character in advanced.config, % is.

[GitJadhav]

@lukebakken I took all the comment notes and just have the config parameter
I am still unable to start the rabbitmq

error,failed_to_read_advanced_c - failed to read advanced.config file.

You should try starting rabbitmq-server in the foreground to get more information.
