Note: Support for custom namespaces was added in version 1.3.0 of the AppSignal for Elixir package.
For more information about what namespaces are, please see our namespaces documentation.
Appsignal.set_namespace/2 was added in version 1.7.0 of the
AppSignal for Elixir package.
This can be done per transaction with custom instrumentation, added in a the controller in a Phoenix application, or set via a plug to configure it for all requests of a certain Phoenix controller.
Once the namespace is set and the application is sending data to the AppSignal servers, the new namespace will appear in the app navigation on AppSignal.com. Note: Data previously reported for the same action is not moved to the new namespace.

To ignore all actions in a namespace you can configure AppSignal to ignore one or more namespaces in your app's configuration. It's also possible to only ignore one or more specific actions.
Ignoring actions or namespaces will ignore all transaction data from this action or namespace. No errors and performance issues will be reported. Custom metrics data recorded in an action will still be reported.
For more information about this config option, see the
ignore_namespaces config option documentation.

You can also configure ignore actions using an environment variable.
