[rabbitmq-discuss] Removing "INFO REPORT" from logs (due to 30gb log file in 1 day)

Thu Jun 23 16:48:05 BST 2011

Hi,

According to the Erlang docs you can disable both SASL and rabbit logs by passing the following parameters to the rabbitmq-server init script:

sbin/rabbitmq-server -kernel error_logger silent -sasl sasl_error_logger false

More docs on the topic here: 

SASL Logs: http://www.erlang.org/doc/man/sasl_app.html
Erlang Kernel Docs: http://www.erlang.org/doc/man/kernel_app.html

Regarding specifying those parameters in a config file, that's possible too.

You can add them to this file for example: http://www.rabbitmq.com/configure.html#config-file

So there you could add an entry like this:

{sasl, [
	{sasl_error_logger, false}
]}

For the SASL logs

And another one like:

{kernel [
	{error_logger, silent}
]}

The problem with this approach is that the command line arguments passed inside the rabbitmq-server script will override what you put on those .config files, as explained here: http://www.erlang.org/doc/man/config.html

"Configuration parameter values in the configuration file will override the values in the application resource files (see app(4)). The values in the configuration file can be overridden by command line flags (see erl(1))."

 I think some tweaking of the rabbitmq-server script will do to solve this problem, specifically this lines:

    -sasl errlog_type error \
    -kernel error_logger '{file,"'${RABBITMQ_LOGS}'"}' \
    -sasl sasl_error_logger '{file,"'${RABBITMQ_SASL_LOGS}'"}' \

Hope this helps,

Alvaro
