When resources (Connect or .pp7) are send to workflow, where is that event logged?

For Connect packages, I see Messenger has the log entry, but it doesn’t log meaningful names:

REQST: File received - 9:16:15 AM
INFO : Processing files from form
INFO : Form C:\ProgramData\Objectif Lune\PlanetPress Workflow 8\Messenger\In\form\dfA00ZZYPIUJE9FA01762174.spl successfully sent to Watch as temp2073153732266898234.spl.OL-package.
REQST: End time - 9:16:16 AM

And when we send from PlanetPress Design (pp7, ptk, ptz) files, I don’t find those logged anywhere.

Messenger only logs the internal name of the package that was sent, which is admittedly useless to you. As for PPress Design, you’d have to look in the Messenger 7 logs on the source machine, but again you’d only find internal names in there.
