Rudder

I've used command_execution_module.cf which is a simple wrap of command_execution.cf with options to execute a command as a module.

No reports come from command_execution_module.cf whereas reports came from command_execution.cf.

Here is the rudder_expected_reports.csv file from a MetaTechnique upgrading Zypper:

Then Rudder expect to have a report of "Command execution module" Component but never have anyone which lead to a "No Answer" state:
