Upgrading Clustered vRLI Deployment

In this post I will walk through steps of upgrading a clustered vRLI deployment. Before preparing for upgrade, make sure to read VMware documentation for the supported upgrade path.

One very important consideration before you start upgrading vRLI:

Upgrading vRealize Log Insight must be done from the master node’s FQDN. Upgrading using the Integrated Load Balancer IP address is not supported.

To start vRLI upgrade, login to the web interface of master node and navigate to Administration > Cluster and click on Upgrade Cluster button. Read More

Configuring AD Authentication in vRealize Log Insight

vRealize Log Insight supports 3 Authentication methods:

  • Local authentication.
  • VMware Identity Manager authentication.
  • Active Directory authentication.

You can use more than one method in the same deployment and users then select the type of authentication to use at log in.

To AD authentication to vRLI, login to web interface and navigate to Administration > Authentication page

vrli-auth01

Switch to Active Directory tab and toggle the “Enable Active Directory support” button.

vrli-auth02

Specify your domain related details and hit Test Connection button to test whether vRLI is able to talk to AD or not. Hit Save button if test is successful.  Read More

Scaling Up Standalone vRealize Log Insight Deployment

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. Read More
