Assuming VCF 4.1 and later, If vRealize Automation is deployed in "vcf-mode" from a vRSLCM instance managed by SDDC Manager and where vRealize Log Insight is already deployed and managed, then vRealize Automation is automatically configured to send logs to vRealize Log Insight Cluster over TCP 9000 - essentially it uses the "vracli vrli set" to configure Fluentd to send the logs over the unencrypted path.

You can use the PowerValidatedSolutions module to return the status of the configuration or set it, too, after deployment.

Ah, gotcha. Yes, it does look like an issue based on a testbed I just looked at moments ago. 

Please login to docs.vmware.com using VMware Customer Connect and use the Send Feedback option. This will open a documentation issue for this VMware Validated Solution that myself and our team will review.

Just sent feedback, thanks. I'll wait to see what we should be doing, I'm guessing a new empty group that has no configuration so that the appliances are still grouped together for easy viewing.

If we update the solution, we'll note changes in the Update History. I'll make a note to review it for the February update if needed.
