To help you get started with using Better Stack in your Rack projects, we have prepared a simple program that showcases the usage of Logtail logger.

You can download the example project from GitHub directly or you can clone it to a select directory. Make sure you are in the projects directory and run the following command:

bundle install

This will install all dependencies listed in the Gemfile.lock file.

Then replace <source_token> and <ingesting_host> in config.ru with your actual source token and ingesting host which you can find by going to Better Stack Telemetry -> Source -> Configure.

http_io_device = Logtail::LogDevices::HTTP.new("<source_token>", ingesting_host: "<ingesting_host>")

To run the example application, run the following command:

rackup

This will start a local server and you visit http://127.0.0.1:9292 in your browser.

You should see the following output:

All done!
Log into your Logtail account to check your logs.

This will create a total of 4 different logs. You can review these logs in Better Stack.

You can visit any path on the server to see the request path being logged in context. Visit /error to see an example exception being logged.
