AppSignal
AppSignal Ruby configuration
Configuration. Important, because without it the AppSignal Ruby gem won't know which application it's instrumenting or in which environment.
In this topic we'll explain how to configure AppSignal, what can be configured in the Ruby gem, what's the minimal configuration needed and how the configuration is loaded.

- Minimal required configuration
- Configuration options
- Configuration load order
- Example configuration file
Minimal required configuration
1 2 3 4 5 | # config/appsignal.yml production: active: true push_api_key: "1234-1234-1234" name: "My app" |
1 2 3 4 | # Environment variables export APPSIGNAL_PUSH_API_KEY="1234-1234-1234" export APPSIGNAL_APP_NAME="My app" export APPSIGNAL_APP_ENV="production" |
The above configuration options are the only required options. All other configuration is optional.
If you use Rails you can even skip the app name, we will use the name of your Rails application.
If you use a framework that is aware of environments and is supported by the AppSignal gem, the environment is detected automatically.
Example configuration file
Here's an example of an appsignal.yml configuration file. It's recommended
you only add the configuration you need to your configuration file.
For the full list of options, please see the configuration options page.
