I created more than 5 service account in GCP to use Pub/Sub services.
Now, I want to delete 4 of the 5 accounts. But I don't know which 4 accounts are not using, which one is active. I don't want to check all the Json config file any more, there are so many servers and applications.
Is there any way to monitor GCP service account activities, such as:
When, Which service account actives in what system from what IP?
Thanks.
