Issue/Introduction

vSphere UI Health Alarm is triggered frequently in the vCenter

 

Environment

VMware vCenter Server 7.x

VMware vCenter Server 8.x

Cause

The alarm triggers when the heap memory allocated to the vSphere-UI process exceeds the warning threshold.

This can be validated in the vSphere-UI logs if the below events are found.
