What should be the order of running discovery on devices - Network Gear, Vmware vCenter, Servers ?

[Manideep Arja]

Hi @Sumit Das1 ,
The order should be Network Gears, Vmware vCenter, Servers

Network Gear (Routers, Switches, Firewalls, etc.)

Why first? These devices form the backbone of your infrastructure. Discovering them first helps ServiceNow build a foundational network topology.
Benefits: Enables identification of IP ranges, routing paths, and connectivity between devices.
VMware vCenter

Why second? vCenter manages virtual environments. Discovering it early helps identify ESXi hosts, clusters, and virtual machines.
Benefits: Allows ServiceNow to map virtual relationships and dependencies accurately.
Servers (Physical and Virtual)

Why third? Once network and virtualization layers are discovered, server discovery becomes more precise.
Benefits: Ensures correct classification and relationship mapping (e.g., which VM is on which host).

Accept the Solution if it is helpful!

Manideep, do we have ServiceNow documentation on this

@Sumit Das1  OOB Shazzam probe runs the port probes in this order, WMI--> SSH-->SNMP-->HTTP (More details in the link: https://www.servicenow.com/docs/csh?topicname=r_PortProbes.html&version=latest)

Following the same order, Server (like a Host), VM ware vCenters (Looking for vcenter process running on those hosts) and then SNMP (till the last IP address) to scan. However, keep each schedule enough time apart to complete earlier one. 

Thanks,

Mannapura, I dont think the port probes have anything to do with the sequence of running discovery of different devices.

Is there any ServiceNow docs which can prove your theory?
