Telemetry

Diffblue Cover captures telemetry (usage) data to help improve Cover services and features. Data is sent to the following endpoints:

  • Diffblue - Telemetry data is sent to Diffblue by default.

  • Cover Reports - Telemetry data can be sent to your Cover Reports instance (if required), allowing you to monitor Diffblue Cover usage across your organization.

Further information on our data collection and policies is provided in the Diffblue Privacy Notice.

Configure telemetry

Telemetry can be configured (if required) using environment variables, and/or a properties file, on the host machine (where Diffblue Cover is being used). Note that these configuration settings apply to Cover Plugin and Cover CLI.

  • Environment variables always take priority and is the recommended method for configuring telemetry - variables listed below.

  • If you use a properties file, create a telemetry.properties file in the home directory under the .diffblue folder (for example, /users/jbrown/.diffblue/telemetry.properties) and define one or more of the properties listed below.

  • If an individual environment variable or property is not found, the default value will be used.
