Hi,
You didn’t say which import yields higher numbers, nor which is more accurate.
It looks like OpenCpp isn’t directly supported…? So at a guess the import of the “SonarQube.xml” is more accurate.
You’ll need to provide full analysis logs from both runs for a more in-depth opinion.
The analysis / scanner log is what’s output from the analysis command. Hopefully, the log you provide - redacted as necessary - will include that command as well.
This guide will help you find them.
