@loopback/example-log-extension not write any log?

[Vn-ChemGio]

Hi guy.
I'm using loopback 4 and try to use module @loopback/example-log-extension to display log

In application.ts, I were wrap BootMixin by LogMixin

BootMixin(
  ServiceMixin(LogMixin(RepositoryMixin(RestApplication)),
))

LogMixin(BootMixin(
ServiceMixin(RepositoryMixin(RestApplication)),
))

And add @log(LOG_LEVEL.DEBUG) to controller

export class PingController {
constructor(@Inject(RestBindings.Http.REQUEST) private req: Request) {}

  // Map to `GET /ping`
  @log(LOG_LEVEL.DEBUG)
  @get('/ping')
  @response(200, PING_RESPONSE)
  ping(): object {
    // Reply with a greeting, the current time, the url, and request headers
    return {
      greeting: 'Hello from LoopBack',
      date: new Date(),
      url: this.req.url,
      headers: Object.assign({}, this.req.headers),
    };
  }
}

But when I call api localhost:3000/ping
Nothing show in console log

So, what I have to do? or where I can see log file

It looks like you're trying to use one of the example packages (@loopback/example-*). These are meant to be used more as example code of actual LoopBack 4 apps rather than extensions.

Perhaps @loopback/logging is what you were looking for?

Thank @achrinza for your answear.
I were try @loopback/example-log to using example package to test, => If it working, I will implement to my project
But nothing to see in console.log.

When I read document of @loopback/logging, I'm not sure my system is supporting FLUENTD_SERVICE , because my devops team told me we using ES log
But this time I have to write log in console.log.
So @achrinza how we work with @loopback/example-log or @loopback/logging to write log in console.log
