I have a real time search that sends an email if there are any results. In Splunk, the search is formatted as I would expect.
In the email version, however, the rows don't format properly - any clue why?
When using list in a triggered alert, it creates "sublines" inside of a true single line.
I would be like going in Excell and hitting Shift+Enter in a cell.
Have you tried doing the following just for the alert?
stats count(cm) as Message by logdata.machineName, logdata.projectIdentifier | (your rename statement)
Nice job showing the problem! I would open a support case.
I notice my reports come out slightly different also. I think this is a bug unless splunk can get this question answered
