AppSignal for Ruby: Demonstration tool

The AppSignal gem ships with a command line tool used to send demonstration samples to AppSignal. Upon running it, it sends an error and performance sample to AppSignal from the user's machine.

This command line tool is useful when testing AppSignal on a system and validating the local configuration. It tests if the installation of AppSignal has succeeded and if the AppSignal agent is able to run on the machine's architecture and communicate with the AppSignal servers.

The same test is also run during installation using appsignal install.

Read more about how to use the demonstration command on the Debugging page.

This tool is available since version 2.0.0 of the AppSignal Ruby gem.
