Integrated Load Balancer (VIP) is showing as Unavailable

Products

• VMware Aria Suite

Issue/Introduction

Cluster nodes are all showing online.

Login to all node's UI shows same status.

Logs are ingested.

However, Integrated Load Balancer (VIP) is showing as "Unavailable" on cluster view.

 

Environment

Aria Operations for Logs 8.18

Cause

On one of the node, prior memory issue may have caused the VIP to latch on pre-existing status and did not reset to correct status.

Following error can be seen from the runtime.log on the problematic node.

ERROR [com.vmware.loginsight.analytics.distributed.AbstractSearchResponseAggregator] [Partial results are being returned as 1 out of 4 nodes failed to respond.  Request token xxxxxxxxxxxxx. Please contact an admin user for more information.]

["LoadBalancerStateUpdaterScheduler-thread-1"xxx.xxx.xxx.xxx ERROR] [com.vmware.loginsight.loadbalancer.LoadBalancerPeerMonitor] [LoadBalancerViolation - No load balancer leader found for last 19 minutes]

 

Resolution

Shutdown and reboot all cluster nodes in vCenter.

Upon reboot completion, VIP status resets and shows correct "Available" Status.
