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.

Usage

On the command line in your project run:

appsignal demo

To run it with a specific environment, see the --environment option.

appsignal demo --environment=production

Standalone run

It's also possible to run appsignal demo without having to install AppSignal in an application. Since most of the config options do not have CLI options, you'll need to use environment variables to configure AppSignal.

gem install appsignal
export APPSIGNAL_APP_NAME="My test app"
export APPSIGNAL_APP_ENV="test"
export APPSIGNAL_PUSH_API_KEY="xxxx-xxxx-xxxx-xxxx"
appsignal demo

Options

Option	Description
`--environment=<environment>`	Set the environment to use in the command, e.g. `production` or `staging`.

Environment option

By default no environment is selected. To make sure AppSignal can be started the correct environment needs to selected with the --environment option or the APPSIGNAL_APP_ENV environment variable.

appsignal demo --environment=production

Exit codes

Exits with status code 0 if the command has completed successfully.
Exits with status code 1 if the command has completed with an error.
