ESXi hosts are not getting discovered in ServiceNow CMDB discovery using a MID Server.

Products

• VMware vSphere ESXi
• VMware vCenter Server

Issue/Introduction

•  ServiceNow CMDB Discovery successfully connects to vCenter and retrieves certain objects (like Datacenter, Folder) but ESXi hosts and VMs residing in it are not being discovered.

Environment

• VMware vCenter Server Appliance
• VMware vSphere ESXi

Cause

This is mostly observed if permission to the AD account is not properly assigned to the respective vCenter inventory objects.

Resolution

• Verify if the AD user account is present.
• Add the AD user to the Global Permission with read-only role and Global > License privilege in vCenter.
• Propagate the permissions to the child objects.
