vRealize log insight can be deployed as a standalone or as a clustered solution. In a clustered deployment the first node is the master node and the remaining nodes are termed as worker nodes. The process of scaling up is pretty straight forward and in this post I will walk through the steps of doing so.
Few things which you should consider before expanding a vRealize Log Insight deployment are:
- vRealize Log Insight does not support WAN clustering (also called geo-clustering or remote clustering). All nodes in the cluster should be deployed in the same Layer 2 LAN.
- Configure a minimum of three nodes in a vRealize Log Insight cluster. 2 node cluster is not supported.
- Verify that the versions of the vRealize Log Insight master and worker nodes are same. Do not add an older version vRealize Log Insight worker to a newer version vRealize Log Insight master node.
- External load balancers are not supported for vRealize Log Insight clusters. You need to use the vRealize log insight integrated load balancer (ILB).
Let’s jump into lab to see the process in action.
In this post I am not including deployment steps of my first vRLI instance as it’s a straightforward forward process. If you are still interested to see the deployment steps then you can follow this old post of mine.
