They're in the Monitoring Console.
This is from Setting to set up. However, can I run a query to check as % for ip or host from index=_internal?
Assuming you have read access to _internal, yes, you should be able to write your own query.
Go to Settings->Monitoring Console->Scheduler Activity: Instance and click on the magnifying glass icon in the Skip Ratio panel. That will open the underlying search in a new tab. Modify that search to your liking then save it as a new report.
