title: How to run mongodb instance in ERROR log level mode?
body: <p>Not able to run mongodb instance in ERROR log level. As defined by mongodb documentation, by default verbosity is 0 which includes information messages. But increasing verbosity to 1-5 will include debug level messages. I need only error messages to be logged in my log file. I am currently using mongodb-3.6.3 version with java driver at client side. </p>
  
  <p>Is there any way to do it? If yes, how to achieve this? I've already tried reducing logs by adding quiet = true in the config file. But still, a lot of unnecessary logs are generated. </p>
