Telemetry

Help to improve Dynatrace’s features and performance. The Dynatrace App Toolkit automatically sends usage statistics and crash reports to Dynatrace anonymously.

To deactivate telemetry reporting for the current session:

export DT_APP_DISABLE_TELEMETRY=1

To deactivate telemetry reporting for your profile in all sessions

1. Run:

   echo "export DT_APP_DISABLE_TELEMETRY=1" >>~/.profile
2. Run:

   source ~/.profile

To deactivate telemetry reporting for your profile in all sessions for Windows

1. Run:

   setx DT_APP_DISABLE_TELEMETRY 1
2. Run:

   refreshenv (it might be necessary to restart your terminal)

Build target

Apps built with the Dynatrace App Toolkit currently target es2021. The target standard is not configurable and based on the state of the JavaScript ecosystem, required features and browser support.

	Target
App UI	es2021
Functions	esnext

Supported file types

App functions can't access the file system. Files types that are allowed and can be imported are: .js, .ts, .json, .txt

Environment Variables

Name	Description	Values	Default Value
DT_APP_PLATFORM_TOKEN	Token that is used for authenticating platform requests. You can use it when you want to skip the default authentication flow of the dt-app.
DT_APP_DISABLE_TELEMETRY	Disables the sending of anonymous usage statistics and crash reports to dynatrace by setting it to 1.	not set or 1	not set
DT_APP_OAUTH_CLIENT_ID	Alternative to setting oauthClientId in app.config.json. Should only be set as an environment variable in combination with DT_APP_OAUTH_CLIENT_SECRET to automate retrieving a SSO-Token. This can be useful for using the CLI in a CI-Pipeline.
DT_APP_OAUTH_CLIENT_SECRET	ClientSecret used for authenticating with the Dynatrace Platform.

Logs

Logs can be found in .dt-app/logs inside your app directory.
