Adding and Removing a Cluster VIP for vRLI managed by vRSLCM


 

Introduction


vRealize LogInsight does not use an external load balancer for balancing load between nodes which are part of vRLI cluster



External load balancer is not supported. Log Insight features an Integrated Load Balancer (ILB) which supports one or more Virtual IP Address (VIPs).


Each VIP balances incoming ingestion and query traffic fairly among available Log Insight nodes.


Each VIP also ensures that incoming ingestion and query traffic is accepted even if some Log Insight nodes become unavailable.


It is recommended that all Log Insight clients, using the web user interface and/or ingestion (via Syslog or the API), connect to Log Insight via a VIP defined below and not directly to a node.


Please refer to the section "Working with an Integrated Load Balancer" of the Online Help



 

I have deployed a single node vRealize LogInsight in my lab through vRSLCM


Since , I have not configured VIP or there it's not a Cluster yet. Under Product properties you would see "Configure Cluster VIP" set to false


Below screenshot shows you the appliance properties , where the VM Name , FQDN and the IP Address of the appliance is shown along with the vCenter where it's placed etc...




 

Configure VIP or Integrated Load Balancer for vRealize LogInsight


Login into vRealize LogInsight 8.x , navigate to cluster under management





Here you would see all of the nodes which are part of cluster if it's already configured. If it's not then you would see a standalone node.


This is the pane where you can configure integrated load balancer for vRLi


I do have an IP which has been reserved for vRLI VIP or vRLI ILB , I have also created a DNS record for resolution purposes


Now , we shall go ahead and click on " New Virtual IP Address " as shown below




Enter the IP and then the FQDN of the VIP. Tags are not mandatory




Click on Save , it will start configuring the VIP or ILB





Once completed , status will be flipped to "Available"



Since this vRealize LogInsight is managed by vRSLCM , now go ahead and perform an inventory sync to reflect cluster properties on vRLI product











Since the Inventory Sync is now complete , if we check the product properties now you would see vRLI cluster IP and then the FQDN too



 

Un-Configure VIP or Integrated Load Balancer for vRealize LogInsight


Under vRLI , click on management and cluster , select the VIP and then delete it






Perform Inventory Sync to refresh product properties on vRSLCM which would remove







As you can see the cluster properties are now removed
