Description :

If you slice the execution of a template (for performance reasons, scaling out), a workflow parent job is created. Successful and failed hosts are only shown in the output of a sliced child job. You have to view every single slice job and filter it on whatever you looking for (e.g. "Host Failed"). The aggregation is manual, persistent only in human memory. Instead of looking into every sliced job, an aggregated view of all sliced job output would be very helpful. Just like if you are running the job on a single slice.

Business Impact :

The customer have to manually aggregate the output of e.g. 7 sliced jobs to get an overview of all failed hosts. If you run a job template in a single slice just as ansible-playbook would do on the command line you do have an easy overview of failed or unreachable hosts. With slices you have to go to every sliced job output and filter it with the event you are looking for. What I suggest is that the sliced workflow job has an filter too, this time filtering or searching on all child jobs and aggregating it in a single view/list.
