DOC: Logging - ibmcb/cbtool GitHub Wiki
The tools writes all logs to a folder located /var/log/cloudbench/USERNAME_*. The Orchestrator-side operations (e.g., vmattach) will be recorded to /var/log/cloudbench/USERNAME_operations.log. When Virtual Application's configuration scripts are executed, the result is logged on /var/log/cloudbench/USERNAME_remotescripts.log. In case of failure it is useful to restart CBTOOL with the option "-v 8". When you run into a bug, please packup the logs folder and send it to us and we'll work with you to get it fixed.
We would also like to start using github's bug tracking system: You could post all the details of your issue there - that would be very helpful.
