摘要： Some embodiments provide novel inline switches that distribute data messages from source compute nodes (SCNs) to different groups of destination service compute nodes (DSCNs). In some embodiments, the inline switches are deployed in the source compute nodes datapaths (e.g., egress datapath). The inline switches in some embodiments are service switches that (1) receive data messages from the SCNs, (2) identify service nodes in a service-node cluster for processing the data messages based on service policies that the switches implement, and (3) use tunnels to send the received data messages to their identified service nodes. Alternatively, or conjunctively, the inline service switches of some embodiments (1) identify service-nodes cluster for processing the data messages based on service policies that the switches implement, and (2) use tunnels to send the received data messages to the identified service-node clusters. The service-node clusters can perform the same service or can perform different services in some embodiments. This tunnel-based approach for distributing data messages to service nodes/clusters is advantageous for seamlessly implementing in a datacenter a cloud-based XaaS model (where XaaS stands for X as a service, and X stands for anything), in which any number of services are provided by service providers in the cloud.

摘要： A method of enhancing log packets with context metadata is provided. The method at a redirecting filter on a host in a datacenter, intercepts a packet from a data compute node (DCN) of a datacenter tenant. The method determines that the intercepted packet is a log packet. The method forwards the log packet and a first set of associated context metadata to a proxy logging server. The first set of context metadata is associated with the log packet based on the DCN that generated the packet. The method, at the proxy logging server, associates a second set of context metadata with the log packet. The second set of context metadata is received from a compute manager of the datacenter. The method sending the log packet and the first and second sets of context metadata from the proxy logging server to a central logging server associated with the tenant.

摘要： A novel centralized troubleshooting tool that enables user to troubleshoot a distributed virtual network with a single consistent user interface is provided. The distributed virtual network being monitored or debugged by the centralized troubleshooting tool includes different types of logical resources (LRs) that placed or distributed across different physical endpoints (PEs). The centralized troubleshooting tool provides functions that allow the user to invoke commands on different physical endpoints in order to collect information about the logical resources running in those physical endpoints. This allows the user to compare and analyze the information from different PEs for a same LR.

摘要： Some embodiments provide a method for troubleshooting a virtual network that is implemented over multiple computing devices, which include first and second host machines that host virtual machines (VMs). Each VM interfaces the virtual network through a set of virtual network interface controllers (VNICs). The method provides a command line interface (CLI) for debugging and monitoring the virtual network. In response to receiving a first command at the CLI that identifies a first VNIC, the method retrieves from the first host machine a first set of network service status data associated with the first VNIC. In response to receiving a second command at the CLI that identifies a second VNIC, the method retrieves from the second host machine a second set of network service status data associated with a second VNIC. The method presents the retrieved first and second sets of network service status data through the CLI.

摘要： Some embodiments provide a method for efficient data message transfer across a hypervisor, service DCN, and containers implementing partner network services. The method allocates memory to a service DCN that operates a set of containers for providing partner network services for data messages received by the service DCN. The service DCN and the containers share the allocated memory and the method stores data messages received by the service DCN in the allocated memory. The method then accesses the data message stored in the shared memory from a set of partner network service containers to perform the partner network services. In some embodiments, the host machine or a process of the host machine on which the service DCN executes also shares the allocated memory. The host machine process, in some embodiments is a kernel process.
