What type of workload information does the VEN monitor?

The Virtual Enforcement Node (VEN) monitors service status and flow data, which is crucial for understanding the interactions between workloads in a network. This information includes the communication flow between applications and services, as well as the states of those services. By capturing flow data, the VEN provides visibility into how different components of workloads are interacting, which helps in applying security policies effectively.

Monitoring service status ensures that administrators are aware of which services are active, running, or even facing issues. This is essential for maintaining application performance and ensuring that security protocols can be enforced appropriately based on the flow of data. In contrast to other options, such as internet usage or system performance metrics, the focus of the VEN is specifically on the secure communication between workloads within a protected environment. This targeted monitoring capability is foundational to Illumio's approach to micro-segmentation and workload security management.
