@JB- To be clear, the request is for the log4j2 config file to be in xml or json, not supporting json or xml log formats
@Romain- I think heterogenous is a great goal— however, with complex hierarchal configurations, the “simplicity” of properties is lost in the structure. Default Log4j2 as properties is illegible by any UX/DX standard. As with features, having structured format (ie xml) for complex data is more manageable. The Developer Experience (DX) gap here is dev-on-laptop writing a simple REST service/camel route, etc and then deploying to karaf has a very different experience with logging. This is especially true for developers without a lot of experience and/or are new to karaf. My suggestion is about trying to unify the log4j2 property file so dev laptop to running karaf has the same default and therefore the same DX. -Matt > On Dec 28, 2021, at 1:55 AM, Romain Manni-Bucau <rmannibu...@gmail.com> wrote: > > My 2cts would be that log4j2 or any configuration in karaf should be > homogeneous with other config files.
