vRealize Log Insight 2.5 improves on the clustering in previous versions with an Integrated Load Balancer (ILB) which allows you to distribute load across your cluster of Log Insight instances without actually needing an external load balancer. The advantage of this over an external load balancer is that the source IP is maintained which allows for easier analysis.
The minimum number of nodes in a cluster is three, the first node becomes the Master node and the other two become Worker nodes.
