title: NestJS: How to set global log level for different environments
body: <p>I am using the NestJS in-built logger. I couldn't find an option to set the global log level. For e.g. log level as 'verbose' for dev environment and log level as 'error' for prod environment.</p>
  
  <p>Also, is there an option to disable the stuff that NestJS adds in the output i.e timestamp and other info and only log the message? I need this as we use Kibana logs and it automatically adds the required fields.</p>
