Publication number: 20240113950Abstract: This disclosure describes techniques for monitoring, scheduling, and performance management for virtualization infrastructures within networks. In one example, a computing system includes a plurality of different cloud-based compute clusters (e.g., different cloud projects), each comprising a set of compute nodes. Policy agents execute on the compute nodes to monitor performance and usage metrics relating to resources of the compute nodes. Policy controllers within each cluster deploy policies to the policy agents and evaluate performance and usage metrics from the policy agents by application of one or more rulesets for infrastructure elements of the compute cluster. Each of the policy controllers outputs data to a multi-cluster dashboard software system indicative of a current health status for the infrastructure elements based on the evaluation of the performance and usage metrics for the cluster.Type: ApplicationFiled: December 7, 2023Publication date: April 4, 2024Inventors: Harshit Naresh Chitalia, Avi K.

Patent number: 11943117Abstract: A variety of different graphical user interfaces are generated that when displayed provide a visual and interactive representation of one or more performance metrics associated with the operation of a computer network. The graphical user interfaces may be used to monitor the underlay computer network for a virtualization infrastructure, as one example. Aspects include grouping the servers of a computer network into a plurality of aggregates, each aggregate comprising one or more servers. A set of probes are configured that are issued by an agent of a server in one aggregate and sent through the computer network to one or more agents in the server(s) of a different aggregate. Responses and other measurements taken based on the issuance of the probes is gathered and analyzed to generate metrics that are then used to generate, at least in part, the information provided in the graphical user interfaces.Type: GrantFiled: September 19, 2022Date of Patent: March 26, 2024Assignee: Juniper Networks, Inc.Inventors: Harshit Naresh Chitalia, Travis Gregory Newhouse, Weixu Zhuang, Sumeet Singh

Patent number: 11765014Abstract: An alarm service can receive an alarm rule as an “intent” that defines a rule in a high level “natural language.” An alarm rule compiler can receive the intent and translate the high level intent into one or more lower level rules that can be programmatically processed by multiple alarm rule execution engines. Devices in a network system can be associated with alarm rule execution engines in a distributed manner. For example, devices in a network can be associated with different instances of an alarm rule execution engine, thus distributing the resource usage for obtaining telemetry data and processing alarms with respect to the devices in a network across multiple alarm rule execution engines.Type: GrantFiled: March 31, 2022Date of Patent: September 19, 2023Assignee: Juniper Networks, Inc.Inventors: Tarun Banka, Aditi Ghotikar, Gauresh Dilip Vanjare, Harshit Naresh Chitalia, Rajenkumar Patel, Yixiao Wei
