Steps to reproduce or a small repository showing the problem:

I'd like to be able to log slow queries to console/file and keep track of average query times with statsd. From http://typeorm.io/#/logging/using-custom-logger, I know that I can define a custom logger, and if I set maxQueryExecutionTime=-1 (since 0 will be falsy), then the custom logger will always be called.

At that point, I can fire statsd.timer as well as check if the query took longer than some threshold and log as well. But this feels more difficult than it should be. I also looked into subscribers but it doesn't seem to track query time.

Is there a better way to do this?
