the different logfiles what are they for..
management-server.log -> Log file of the cloud-management service, all actions being performend by the cloudplatform managment service are logged here (incl. the errors ofcourse)
catalina.out -> Tomcat Catalina logfile (Catalina.out is the standard destination log file for System.out and System.err, JVM loggers that print information about fatal errors in the JVM)
api-server.log -> Logging of all the api calls send to the CloudPlatform API server
awsapi.log -> Same as api-server.log but for the AWS-api calls
acces_log -> Access log for the HTTP daemon (who (IP) and when, kind of request).
usage.log -> Log file of the cloud-usage service / When running an Usage Server all logging is located here.
