Install a logging service to Parse Server

I’d like to know more about what is going on with my parse server and considering installing a logging service such as DataDog / Papertrail (solarwinds).

I note that there is a LoggerAdaptor, however I’m unsure how I can use this with setup instructions such as these: https://docs.datadoghq.com/integrations/express

For example, in the parse-server-example, I’d add the data dog middleware before this line: https://github.com/parse-community/parse-server-example/blob/master/index.js#L31
