vRealize Code Stream provides logs to aid in troubleshooting. You can retrieve these logs from the user interface, perform a comparison between a successful and failed pipeline instance, and correct some of the problems.
If you are asked for log files while you are troubleshooting a failed pipeline instance, you can retrieve them from the file system of the vRealize Automation appliance, a remote machine, or a local machine.
When the log storage is full, the pipelines fail to continue with the execution of tasks. In such a scenario, delete the log files or move the logs to another location for future reference.
