Some embodiments provide a method for clustering a set of data compute nodes (DCNs), which communicate with each other more frequently, on one or more host machines. The method groups together guest DCNs (GDCNs) that (1) execute on different host machines and (2) exchange network data among themselves more frequently, in order to reduce interhost network traffic. The more frequently-communicating GDCNs can be a set of GDCNs that implement a distributed application, GDCNs of a particular tier in a multi-tier network architecture (e.g., a web tier in a three-tier architecture), GDCNs that are dedicated to a particular tenant in a hosting system, or any other set of GDCNs that exchange data among each other regularly for a particular purpose.

Monitoring and optimizing interhost network traffic

For a network including multiple host machines that together implement at least one logical network including a firewall, some embodiments provide a method for collecting traffic flow data that includes identifiers for firewall rules applied to the traffic flow and a logical entity identifier. In some embodiments, the host machines receive traffic monitoring configuration data for a logical network. The traffic monitoring configuration data in some embodiments indicates a set of logical entities of the logical network for which to collect traffic flow data and a set of traffic flow data collectors associated with the set of logical entities. The indicated logical entities may be logical forwarding elements (logical switches, routers, etc.) or logical ports of logical forwarding elements.

Internet protocol flow data including firewall rules

Example methods are provided for configuring traffic flow monitoring in a virtualized computing environment. The method may comprise identifying a first logical entity and a second logical entity for which traffic flow monitoring is required and determining a span associated with the first logical entity and the second logical entity. The span may include a first host supporting the first logical entity and a second host supporting the second logical entity. The method may also comprise, based on the span, configuring the first host to monitor a first traffic flow travelling through the first logical entity at the first host, and the second host to monitor a second traffic flow travelling through the second logical entity at the second host.
