  -alsologtostderr
    	log to standard error as well as files (no effect when -logtostderr=true)
  -alsologtostderrthreshold value
    	logs at or above this threshold go to stderr when -alsologtostderr=true (no effect when -logtostderr=true)

    	This file contains the trusted certificate for RabbitMQ server authentication. (default "/etc/rabbitmq-tls/ca.crt")
  -default-user-file string
    	Absolute path to file containing default user username and (updated) password. Its directory will be watched for changes. (default "/etc/rabbitmq/conf.d/11-default_user.conf")
  -legacy_stderr_threshold_behavior
    	If true, stderrthreshold is ignored when logtostderr=true (legacy behavior). If false, stderrthreshold is honored even when logtostderr=true (default true)
  -log_backtrace_at value
    	when logging hits line file:N, emit a stack trace
  -log_dir string
    	If non-empty, write log files in this directory (no effect when -logtostderr=true)

  -log_file_max_size uint
    	Defines the maximum size a log file can grow to (no effect when -logtostderr=true). Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)

  -v value
    	number for the log level verbosity
  -vmodule value
    	comma-separated list of pattern=N settings for file-filtered logging
