During the bring-up process, vRealize Log Insight is deployed and configured to collect logs from the management domain components (vSphere, NSX Manager, and SDDC Manager). To enable logging on VI workload domains, you must provide your own license for vRealize Log Insight. After you enter the license key on the vRealize Log Insight UI and enable logging in Cloud Foundation, workload domains are automatically connected to vRealize Log Insight.
Once logging is enabled for workload domains, you cannot turn off this setting.
