At the moment, all site related audit log entries do not explicitly denote which site was affected by that action.
Example:
- Remove someone from your site and check your audit logs, the message displayed will be "Removed someone@somedomain.com from site".
The suggestion is to:
- include the site name as reference to that text: "Removed someone@somedomain.com from the site mysite.atlassian.net"
- Support filtering on this new parameter.
