If VMware Cloud Director on Linux fails or if it is not operating properly, you can examine the log files to determine the cause of the problem.

VMware Global Support routinely requests diagnostic information handling support requests. You can use the vmware-vcd-support script to collect host log information, and VMware Cloud Director logs. For more information about collecting diagnostic information for VMware Cloud Director, see https://kb.vmware.com/s/article/1026312. When running the vmware-vcd-support script, the logs might include information about decommissioned or replaced cells with status FAIL. See, https://kb.vmware.com/s/article/71349.
