Hi all, Just working on a solution for centralised logging in our development environment, and it would be good to get some feedback. The solution until this morning was this: - Developers build apps with their own logback.xml inside - These get deployed to jboss. A system property for the logback file kicks in, and the logback file on jboss takes precedence over the application one. This logback file has a gelf appender, and all logging is done centrally. This works perfectly, logback is working well, logback-gelf is working well to. The only problem with it is once more applications are deployed. When looking at logs we suddenly have no idea which app a log is coming from. The change of plan would be to use the contextName. What I was thinking was that the war files get stripped at deploy time, their logback files removed and replaced with a generic one (that has the gelf stuff). This logback config would have a contextName which would be written to on the fly. The war would then get re-assembled and deployed. Any feedback appreciated, the basic goals are that all applications should be logging the exact same way, centrally, and that is should be possible to distinguish which app a log has come from given that multiple apps can be deployed to the same app server. Many thanks :)
