You might want to rename an existing application to something your team is used to. For example Plumbr might have discovered your application via http://testbilling.example.com:8080 but your team is used to calling to this application “Billing Test”.
Renaming an application is possible via Plumbr user interface accessible at https://app.plumbr.io. In the application detail view you can click on the settings icon next to the application name and change the existing name to the one you prefer.
With this change, the historical interactions referring to the previous application are also updated. So for example when you had 10 interactions with http://testbilling.example.com:8080 application you renamed to “Billing Test” then all the new interactions and existing 10 interactions will be referring to “Billing Test” app.
