for more details, have a look at lib/constants.rb.

⁠post json example

e.g.

curl --header "Content-Type: application/json" \
  --request POST \
  --data '{"username":"xyz","password":"xyz"}' \
  http://gelf:fleg@localhost:4567/log

this will post the json to sinatra and redirect it to graylog.

1. Bundle gems locally:

$ bundle install

1. Run app from root. Will load app on http://localhost:4567⁠ by default.

$ bundle exec rackup config.ru -p 4567
