    Abstract: Some embodiments provide a novel method for collecting and reporting attributes of data flows associated with machines executing on a plurality of host computers to an analysis appliance. Each host computer, in some embodiments, is responsible for collecting and reporting attributes of data flows associated with machines executing on a host computer. The host computer, in some embodiments, first eliminates duplicative flow group records and then aggregates the flow data according to a set of received keys that specify attributes that define the aggregation. For example, a simple key that specifies a set of machine identifiers (e.g., a VM ID) as attribute values will, for each machine identifier, aggregate all flows with that machine identifier into a single aggregated flow group record. In some embodiments, the host computer includes a flow exporter that processes and publishes flow data to the analysis appliance.
