Knowledge Base: How do I change my application name?

By default, all agent data is rolled up into one application named "My Application". You can rename the application by modifying the app_name setting in the newrelic.yml configuration file. Your data can be broken up into as many applications as you like by setting a different app_name for different agents. An application can be comprised of many agents.

You can group metric data under up to three names, by setting the app_name parameter to a semicolon-delimited list of names. The agent will report metrics to each name in the list. For example, you could report an agent's data to an RPM "application" named after the host the instance is running on, as well as to the actual application name.
