The AppSignal for Node.js package ships with a command line tool used to send demonstration traces to AppSignal. Upon running it, it sends an error and performance trace 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.Read more about how to use the demonstration command on the Debugging page.
