Discovery of ESX servers

Discovery identifies and classifies information about ESX servers through the discovery of vCenter and not from the direct discovery of any ESX servers.

For a description of the VMware architecture and component relationships, see vCenter data collected.

For a discussion of how Discovery collects information on datastores and establishes the relationships between the ESX hosts and the storage disks attached to the datastores, see Datastore Discovery

Required Roles

Users with the itil and asset roles can access ESXii and ESXi configuration item (CI) records. To run discovery on vCenter servers, users must have the discovery_admin role.

Credentials required

To run a complete Discovery of vCenter/ESX servers, you need vCenter credentials. If the vmapp port probe is disabled, you must use Windows credentials to access the Windows host on which the vCenter server runs.
Note: Make sure to select a credential Type of VMware.

ESX server Discovery components

After running the vCenter classifier, Discovery launches the VMware - vCenter Datacenters probe, which launches the probes that explore the ESX server. For the complete list of vCenter probes, see List of Discovery probes.

Table 1. ESX Server Discovery Components
Component Name Description
Classifier vCenter Classifies stand-alone vCenter servers.
Probe VMWare - vCenter ESX Hosts Creates records for ESX servers and hostmounts. Creates relationships between ESX servers and vCenter components. Triggers probes for storage Discovery.
Probe VMWare - vCenter ESX Hosts Storage Creates records for ESX host hardware: network adapters, disks, HBAs, FC ports, iSCSI and FC disks. Creates relationships between DAS/iSCSI/FC disks and datastore disks.
