Scans run but reports come back with no findings and severity "Error"

Hi,

the logging configuration can be found / is documented in the INSTALL file shipped with the sources of each component (see below).

One important note as no used versions of OpenVAS/GVM 9 was provided yet:

Recently i have seen quite a lot user reporting issues but still running outdated versions of the OpenVAS/GVM components. Please compare your current used versions with the GVM-9 (stable, initial release 2017-03-07) ones to avoid that you’re having issues caused by such outdated versions.

Note: Logging configuration of the scanner the same way like with the other components is available with the next major release:
