About near real-time discovery of VMware events
With near real-time discovery of VMware events, any change in the state of a virtual machine (for example, VM powered on) and changes occurring at the vCenter Server infrastructure-level (for example, VM created) in the Management Server domain are updated in the Veritas InfoScale Operations Manager database in near real-time.
The near real-time discovery of VMware infrastructure enables the partial discovery of ESX servers managed under a vCenter Server. For example, if an SNMP trap is received for a virtual machine (VM1) hosted on ESX1, Veritas InfoScale Operations Manager runs the discovery cycle only for ESX1. Other ESX servers under that vCenter Server are not re-discovered. This discovery is triggered by the event notification from the VMware vCenter Server to the Management Server using SNMP traps.
For near real-time discovery, ensure to configure the VMware vCenter Server and the Management Server in the same domain. This discovery is supported for the following events occurring at a VMware vCenter Server-level:

| Virtual machine Distributed Resource Scheduler (DRS) powered on | DRS VM powered on | 6.0, or later |
| Virtual machine suspended | VM suspended | 6.0, or later |
| Virtual machine created | VM created | 6.1, or later |
| Virtual machine migrated | VM migrated | 6.1, or later |
| Hot migration: A powered-on virtual machine is migrated from one ESX server to another ESX server. | ||
| Virtual machine relocated from one ESX server to another | VM relocating | 6.1, or later |
| Cold migration: A powered-off virtual machine is migrated from one ESX server to another ESX server. | ||
| Virtual machine renamed | VM renamed | 6.1, or later |
| Virtual machine migrated to another host by VMware DRS (Distributed Resource Scheduler) | DRS VM migrated | 6.1, or later |
Note: The near real-time update of virtual machines is supported on VMware vCenter Server 4.x, 5.x and 6.0.
