VMware Technical Support routinely requests diagnostic information when you submit a support request. This diagnostic information contains product-specific logs and configuration files from the host on which the product runs.
vRealize Orchestrator Appliance logs are stored in the /data/vco/usr/lib/vco/app-server/logs/ directory. You export the logs of your vRealize Orchestrator Appliance deployment by logging in to the appliance command line and running the vracli log-bundle command. The generated log bundle is saved on the root folder of your vRealize Orchestrator Appliance.
