How can I check which feature of the app are used and where?
Starting with v2.2.0 version of AM Utils and above you are able to find out how much the AM Utils app is used in your Jira instance.
To do this, go to Administration → Manage apps → Am Utils → Workflow Viewer. For more details, click here.
Other way is to make the request to your DB:
SELECT workflowscheme.name, workflowschemeentity.scheme, issuetype.pname, workflowschemeentity.issuetype FROM issuetype, workflowschemeentity, workflowscheme WHERE issuetype.id= workflowschemeentity.issuetype andworkflowscheme.id= workflowschemeentity.scheme and workflowschemeentity.workflow in (SELECT jiraworkflows.workflowname FROM jiraworkflows WHERE jiraworkflows.descriptor like '%ru.andreymarkelov.atlas.plugins%');
