How delete or filter metrics or events from old sources?

Hello,

Right now I’m receiving data from different sources from old systems that I no longer have access and the key that these systems are using is the Default Key, so far I can understand this key cannot be deleted or disabled, so I’m ingesting my newrelic with trash.

What option do I have?

Thank you

Hi, @aldez: If you are an administrator of your account, you may create a new license key and delete the old one. You will need to update your current systems to use the new key, but the old systems will no longer be able to report to your account.
