Applications
Applications (previously known as "sites", also referred to as "apps") are Ruby, Elixir and JavaScript front-end applications monitored by AppSignal. Every application is unique by the combination of its name and environment.
A list of Applications appears on the Application index and in the application quick switcher. Every application has a parent organization, which can have multiple applications. (Exception: Organizations created by the Heroku add-on only support one application.)
Adding applications
If you're just getting started with AppSignal and haven't set up your first app yet, please follow the add a new application guide first.
Read our add a new application guide.
Environments
An application can have multiple environments as long as every environment uses the same application name. Every environment is currently listed separately on the Application index.
- "Demo application" - development
- "Demo application" - production
- "Demo application" - staging
- "Demo application" - test
Namespaces
Namespaces are a way to group error incidents, performance incidents from actions, and host metrics in your app. By default AppSignal provides three namespaces: the "web", "background" and "frontend" namespaces. You can add your own namespaces to separate parts of your app like the API or Admin panel.
Namespaces can be used to group together incidents that are related to the same part of an application. It's also possible to configure notification settings on a per-namespace level.
