Demo

Once you've deployed Logtap demo, you will need to drain your web app's logs to Logtap. For example, if Logtap app got deployed as serene-wookie-1234 and your web app is acme-www-prod, you'll need to do this:

$ hk drain-add -a acme-www-prod https://serene-wookie-1234.herokuapp.com

You can now see Logtap demo producing some stats based on log messages received from acme-www-prod:

$ hk log -a serene-wookie-1234 -s app
