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.
