vRealize Automation collects data from infrastructure source endpoints and their compute resources.

Data collection occurs at regular intervals. Each type of data collection has a default interval that you can override or modify. Each type of data collection also has a default timeout interval that you can override or modify.

IaaS administrators can manually initiate data collection for infrastructure source endpoints and fabric administrators can manually initiate data collection for compute resources.

Table 1. Data Collection Types

Data Collection Type

Description

Infrastructure Source Endpoint Data Collection

Updates information about virtualization hosts, templates, and ISO images for virtualization environments. Updates virtual datacenters and templates for vCloud Director. Updates regions and machines provisioned on them for Amazon. Updates installed memory and CPU count for physical management interfaces.

Endpoint data collection runs every 4 hours.

Inventory Data Collection

Updates the record of the virtual machines whose resource use is tied to a specific compute resource, including detailed information about the networks, storage, and virtual machines. This record also includes information about unmanaged virtual machines, which are machines provisioned outside of vRealize Automation.

Inventory data collection runs every 24 hours.

The default timeout interval for inventory data collection is 2 hours.

State Data Collection

Updates the record of the power state of each machine discovered through inventory data collection. State data collection also records missing machines that vRealize Automation manages but cannot be detected on the virtualization compute resource or cloud endpoint.

State data collection runs every 15 minutes.

The default timeout interval for state data collection is 1 hour.

Performance Data Collection (vSphere compute resources only)

Updates the record of the average CPU, storage, memory, and network usage for each virtual machine discovered through inventory data collection.

Performance data collection runs every 24 hours.

The default timeout interval for performance data collection is 2 hours.

vCNS inventory data collection (vSphere compute resources only)

Updates the record of network and security data related to vCloud Networking and Security and NSX, particularly information about security groups and load balancing, for each machine following inventory data collection.

WMI data collection (Windows compute resources only)

Updates the record of the management data for each Windows machine. A WMI agent must be installed, typically on the Manager Service host, and enabled to collect data from Windows machines.

Cost data collection (compute resources managed by vRealize Business Standard Edition only)

Updates the CPU, memory, and storage costs for each compute resource managed by vRealize Business Standard Edition. The costs of catalog items that can be provisioned by using the compute resources are updated.
