Hi, this page shows how to integrate AWS using the ActiveGate. Search in that page for "If you want to monitor multiple accounts" and you'll see the instructions for monitoring each account (I'm not placing them here in case the instructions change in future and this misleads people who come to this post in future - the docs are always the most up to date instructions).
If you need additional assistance, just reach out to DynatraceONE via in product chat (top right corner of the tenant) and they can assist.
