Reduce verbosity in sonarscanner for .net

SonarQube Server / Community Build
, ,
1

We have repos in .NET 10 where we are using dotnet sonarscanner (version 11.2.1) to analyze the code (in AWS CODEBUILD), the configuration of sonar is currently like this:

dotnet sonarscanner begin
/k:"project"
/v:"$CODEBUILD_BUILD_NUMBER"
/n:"project"
/o:"organization"
/d:"sonar.coverageReportPaths=src/test-results/coveragereport/SonarQube.xml"
/d:"sonar.host.url=https://sonarcloud.io"
/d:"sonar.token=$SONAR_TOKEN"
/d:"sonar.language=cs"
/d:"sonar.scanner.scanAll=false"
/d:"sonar.branch.name=$BRANCHNAME"
/d:"sonar.sourceEncoding=UTF-8"
/d:"sonar.exclusions="

dotnet sonarscanner end
/d:"sonar.token=$SONAR_TOKEN"

With that configuration sonarscanner end writes about 5k lines of INFO logs that is just noise and makes it difficult to find an error, and example of such logs are this:

Is there way to reduce the logs just for warnings and errors? tried adding this line /d:“sonar.log.level=WARN” but it didnt make a difference, and besides the noise in the consolo those logs are being processed by CloudWatch so its costing us money.

Currently we have this dotnet sonarscanner end >/dev/null 2>&1 to void all those logs with the issue that if something fails we are in the dark.

Hi,

did you already try to set d:sonar.verbose=false?

Source: SonarScanner for .NET | SonarQube Server 9.8 | Sonar Documentation

Seems like INFO is the highest possible level to define according to the docs - see Logging

5

It didn’t make any difference in the amount of logs

Hi @JuanZamudioGBM ,

Thanks for the feedback!
There is no inbuilt way to reduce the verbosity of the scanner, but I will be converting that particular line into a debug log.

I can’t guarantee results but rather than dotnet sonarscanner end >/dev/null 2>&1 you could grep/select the output so that warnings/errors are still logged.

Something like dotnet sonarscanner end 2>&1 | grep -iE "WARN|ERROR"
For powershell dotnet sonarscanner end 2>&1 | Select-String -Pattern "WARN|ERROR"

that was it, thank you for your help
