It is useful to understand who created or deleted an IDE. To achieve this, use Acquia CLI, as Acquia CLI lets you filter out your Cloud Platform notifications easisly. Ensure that you adjust the --limit parameter to make it relevant. The rule of thumb is: the more you have Cloud Platform notifications, the more you’ll have to increase the limit.
$ acli api:applications:notification-list myapplication --limit=100 | grep -B2 -A1 IDE
