Papermill is a simple sinatra front-end to Bunyan. Papermill was designed to query and analyze documents stored in a MongoDB capped collection.


Simply clone the repo to the location from which you want to serve the papermill with your favorite app server. The only configuration required is a bunyan configuration file to hook papermill up to MongoDB through Bunyan.


Copy config/bunyan.example.rb to config/bunyan.rb and change the settings to match your MongoDB configuration.


  • Web-based interface for searching, querying and filtering bunyan logs
  • Statistics with pretty graphs (using raphaeljs)


  • Allow data export in json format
