Publication number: 20240214290Abstract: The disclosure provides a method for measuring network latency between hosts in a cluster. The method generally includes receiving, by a first host, a first ping list indicating the first host is to engage in a first ping round with a second host; executing the first ping round with the second host, wherein executing the first ping round comprises: transmitting first ping requests to the second host; calculating a network latency for each of the first ping requests; and determining a first average network latency between the first host and the second host based on each of the network latencies calculated; determining the first average network latency is above a threshold; determining a cause of the first average network latency being above the threshold; and selectively triggering or not triggering an alarm based on whether the cause is determined to be a hardware or software layer impact, or neither.Type: ApplicationFiled: February 7, 2023Publication date: June 27, 2024Applicant: VMware, Inc.Inventors: Sifan LIU, Yu WU, Jin FENG, Jianan FENG, Kai-Chia CHEN

Patent number: 11848769Abstract: Example methods and systems for request handling with automatic scheduling are described. In one example, a computer system may receive, from multiple client devices, respective multiple requests that are generated and sent according to a first set of control parameters. Based on the multiple requests, request characteristic(s) may be monitored to determine whether an automatic scheduling condition is satisfied. In response to determination that the automatic scheduling condition is satisfied, the computer system may assign a second set of control parameters to the respective client devices and instruct the client devices to generate and send respective multiple subsequent requests according to the second set of control parameters to cause a modification of the request characteristic(s).Type: GrantFiled: July 22, 2022Date of Patent: December 19, 2023Assignee: VMWARE, INC.Inventors: Chen Jing, Jin Feng, Sifan Liu, Yu Wu, Jiushi Wan

Publication number: 20220189615Abstract: A decentralized method for generation and management of health monitoring related tasks in a hyperconverged infrastructure (HCl) environment is provided. The hosts in the HCl environment each include a health agent and a task manager. The health agent collects health results from health checks and stores the health results in a shared database that is shared by the hosts. The task manager generates a health monitoring related task in response to the health results being indicative of a change in health status, and stores the health monitoring related task in a task pool that is also shared by the hosts. Any of the hosts can obtain and execute the health monitoring related tasks in the task pool based on a task priority and load balancing criteria.Type: ApplicationFiled: January 28, 2021Publication date: June 16, 2022Applicant: VMware, Inc.Inventors: Xiang YU, Yu WU, Yang YANG, Sifan LIU, Jin FENG, Xiaohua FAN
