Need a search query to find the list of alerts reports and dashboards and their user names and its status enabled or disabled
For savedsearches try this:
| rest /services/saved/searches | search "eai:acl.owner"="admin" | table eai:acl.owner title disabled
And for dashboards scheduled for PDF delivery:
| rest /services/scheduled/views | table eai:acl.owner action.email.to title disabled
