Continuing log4j detection
If you don't have server scanning tools like Nessus or Tenable that are capable of detecting log4j (nested or mitigsted), you could set up ad-hoc scanning with an open source tool like https://github.com/mergebase/log4j-detector

Log4 detection by enterprise tools
We're using Qualys free tool https://github.com/Qualys/log4jscanwin and it has a quite detailed output, and as far as I can tell it can also be read from Qualys cloud agent (we don't have it so I don't know how effective it is)

Qualys Scans not finding Log4j, but Qualys stand-alone Log4j Vulnerability Scanner does?
Here's the link to the stand-alone scanner: GitHub - Qualys/log4jscanwin: Log4j Vulnerability Scanner for Windows Very much worth having.
