Data Sources

We collect data about the state of the hosts and network devices in your system via a variety of methods: WMI, SSH, SNMP, VMware's API, Netflow, database metadata, etc. We may collect against the same device using multiple collection methods. In order to distinguish between data about a virtualized server gathered using VMware's API and data collected directly from that server's operating system (through WMI, SSH, or SNMP), we may refer separately to the server's VMware-sourced data and its data collected directly from the device's OS. While the metrics collected are typically ways of measuring the same property of the system in question, they can differ from each other due to differences in data availability, collection interval, or sampling method.

For the purposes of cloud cost estimation, we prefer data collected from VMware if both that and directly-collected data were available throughout the assessment's collection period.
