It does not provide a command line parameter to do so. Is there an alternative way to set it?
I’m not sure there’s a clean way to set it when you start using
daml json-api. If you use the standalone JAR, you should be able to pass in logback config using
java -Dlogback.configurationFile=... -jar ....
The default JSON API logback config is in
~/.daml/sdk/1.4.0/daml-sdk/json-api-logback.xml. I don’t recommend manipulating it, but I think it can reasonably serve as a template.
The logback file is your only option atm.
