Here is a handy way to skim all the job results from - Rule and - Gen searches with ES to look for issues.
| rest splunk_server=local count=0 /servicesNS/-/-/search/jobs/
| where match(label,"Rule$|Gen$")
| table label, eai:acl.owner, eai:acl.app, isFailed, messages.warn, messages.fatal, messages.error
