Oliver Scholz commented on ARTEMIS-2922:
----------------------------------------
Well, we use the CLI for maintenance and analysis. As can be seen in my
example, the large message was also produced with the CLI. See envrinonment
description. The example here only serves to simply reproduce the subject
matter.
Would you really recommend a different tool than the CLI for maintenance work?
