What is user groups and permissions?
The User Group Permissions screen allows you to assign or revoke permission belonging to user groups and to "embed" user groups (along with associated permissions) into other user groups. When users are associated with a user group, they "inherit" the permissions of the user group.
Where can users and groups be managed in Dynatrace managed?
