Fake alerts created by Ticketing tools that are received from Aria Ops

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

- The issue is on a ticketing tool receiving alerts and warning from ARiaOps.

- No Alerts show up on the Aria Ops, vCenter, yet ticketing tools picks up these CPU Demand Symptom Warnings as exceeding threshold from Aria Ops

- No CPU alerts set on the VM level running on vSphere default policy

Environment

Aria Operations 8.x

Cause

- It's VM's CPU demand Symptom Warnings seen by Ticketing tool as Alert. CPU demand Symptom is monitored by CPU Limit settings on VM.

- This property is set with default policy settings, the property metrics showing warning is because the -1 indicates unlimited CPU limit

- Warning triggered only when the VMs utilize more than 1000MHz CPU demand that somehow on Aria it sees as exceed -1 limit. VM settings
