Hello,

Is it possible to change canton nodes (participant and domain) log verbosity at runtime?

Thank you

Hi David,

Since Canton uses Logback Classic, you can specify a custom logging configuration when starting your domain components.

You can specify the log level here:

`JAVA_OPTS="-Dlogback.configurationFile=./path-to-file.xml" ./bin/canton --config ...`

I found a barebones logback config in one of our example projects. I cannot guarantee that it’s use in this project matches your setup perfectly, but I think it could be [a good place to start](https://github.com/digital-asset/ex-secure-daml-infra/blob/98ef94810e9c893fe75abb5c29db5338cea8fa1d/client-app/src/main/resources/logback.xml)

Hi David,

You should be specify a custom configuration file as shown in the previous response and use the scan feature of Logback: [Chapter 3: Configuration](https://logback.qos.ch/manual/configuration.html#autoScan).
