Embodiment Construction

[0020] figure 1 An illustrative environment is shown in which a client computing device 105 communicates packets 115 over a network 130 with a computer server 110 , possibly operating in a data center. Networks may include local area networks, wide area networks, and the Internet. Computing device 120 local to the computer server may be configured with a user interface to enable user 125 to control aspects and operations on the computer server. The computer servers in the data center may be associated with cloud service providers that provide solutions to customers operating customer computing facilities. For example, a computer server may host virtual machines or containers, each of which is associated with and accessible to a unique client. Virtual machines and containers can provide solutions for client computing devices, such as data analysis, data storage, and artificial intelligence processing. A single computer server can host multiple virtual machines and / or contain...

Abstract

A packet monitoring application instantiated on a server hosting a virtualized network stack is utilized to track data packet propagations and drops at each component within the network stack to reduce the amount of time to identify a root cause for latency issues. The packet monitoring application can be selectively enabled or disabled by an administrator. Components within the virtualized network stack report packet drops and successful packet propagations to the packet monitoring application, which can filter the packets based on input parameters. Thus, a user can select at what level of granularity to filter packets within the virtualized network stack while being able to assess each packet's traversal through each component within the network stack. The packet monitoring application can also perform post-processing of on the filtered data packets to determine latency among components or sections of the virtualized network stack.

Description

Background technique [0001] Data centers can host virtual machines, or containers, that run applications and software offered to customers for utilization. A virtualized network stack running within each computer server in a data center may have multiple components for receiving and passing packets. Each component in the virtualized network stack provides unique capabilities that can become a point of failure for data reception and transmission (such as dropped packets or increased latency). In some cases, issues customers discover when accessing their virtual machines or containers can make it difficult to determine the root cause of latency occurring in the virtual networking stack. Contents of the invention [0002] A packet monitoring application instantiated on the server hosting the virtualized network stack is used to track packet propagation and discards by each component within the network stack to reduce the amount of time to identify the root cause of latency iss...
