I'm trying to set up some third party appenders in a java app (which is a web API) - the appenders are libraries which are added as dependencies. This is a maven app, and those libraries are Raven (via Sentry) and Logentries. They accept logs and provide GUIs to view them.
Things work fine locally - when run locally logs throughout the app successfully show up in both Logentries and Sentry. The configuration is successfully found and parsed fine in both environments. My log4j2.xml config and output when starting the server for both environments is included below.
On the staging environment I'm seeing logs which say CLASS_NOT_FOUND, so maybe this is a class path issue? Any ideas?
config
