Abstract

Systems, methods, and computer-readable media for detecting sensor deployment characteristics in a network. In some embodiments, a system can run a capturing agent deployed on a virtualization environment of the system. The capturing agent can query the virtualization environment for one or more environment parameters, and receive a response from the virtualized environment including the one or more environment parameters. Based on the one or more environment parameters, the capturing agent can determine whether the virtualization environment where the capturing agent is deployed is a hypervisor or a virtual machine. The capturing agent can also determine what type of software switch is running in the virtualized environment.
