How is a node identified in the Node Details Hardware field as virtual or physical (Nodes.EntityType)

Table of contents

Updated May 11, 2017

Overview

This article provides information on how a node is identified in the Node Details Hardware field as virtual or physical (Nodes.EntityType).

Environment

All Orion Platform versions

Detail

The Hardware field display is populated from the Nodes.EntityType SWIS field. 

The value depends on whether the node is recognized as a Virtual Machine or it has an entry in the VIM_VirtualMachines table. For example, when monitored by VIM or one of its network cards such as MAC address, it starts with one of the following VMWare vendor prefixes: 

  • 0003FF%
  • 000C29%
  • 005056%
  • 000569%
  • 001C14%

.

The possible values are:

  • Physical - a node is a physical machine. 
  • Virtual (host unknown) - a node has an entry in the VIM_VirtualMachines table but the ESX host that is running the VM is not managed and the MAC address vendor prefix belongs to VMWare.  
  • Virtual (hosted by <NodeCaption> - a node has an entry in the VIM_VirtualMachine table and the ESX host that is running the VM is managed by Orion and IVIM.

 

The Nodes.Entitytype field is found in the Nodes table where physical nodes are set to Orion.Nodes. When a node is added to Orion (using the Add Node wizard or Discovery) and is recognized as an ESX/vCenter host, the fields in the dbo.Nodes table is updated. These fields are set to Orion.Nodes when discovered as an ESX host during a vCenter polling.

For example:

EntityType          Orion.VIM.Hosts/Orion.VIM.VCenters
Vendor               VMware Inc.
MachineType This depends on the VMWareproductname property.
SQL Select NodeID, ObjectSubType, Caption, Vendor, EngineID, MachineType, IsServer, Severity, EntityType
