Embodiment Construction

[0017] As described herein, one aspect of the invention includes problem determination and diagnosis in a shared dynamic cloud. At least one embodiment of the invention includes a three-stage approach that identifies faults as early as possible with limited training or application knowledge. After initial detection and fault localization of affected virtual machines and resources, the diagnostic engine uses expert-defined fault signatures to classify faults into one of several types (cloud-related or application-related). As detailed herein, the architecture of at least one embodiment of the present invention allows the system to be extended to new applications, monitored metrics, and analysis techniques.

[0018] Accordingly, embodiments of the invention include distinguishing between cloud-related anomalies and application failures. Cloud-related anomalies can include incorrect virtual machine (VM) size settings, impacts due to sharing, and reconfiguration and / or migration,...

Abstract

A method and a system for problem determination and diagnosis in a shared dynamic cloud environment. The method includes monitoring each virtual machine and physical server in the shared dynamic cloud environment for at least one metric, identifying a symptom of a problem and generating an event based on said monitoring, analyzing the event to determine a deviation from normal behavior, and classifying the event as a cloud-based anomaly or an application fault based on existing knowledge.

Description

technical field [0001] Embodiments of the present invention generally relate to information technology, and more particularly, to virtualization technology. Background technique [0002] Large data centers can experience frequent failures, which are a major factor in data center management costs. Data centers can generate large amounts of monitoring data, but detecting failures and corresponding root causes from this data is difficult. Typically, this task is performed by manually observing the data using predefined thresholds. [0003] In addition, virtualized cloud environments present new challenges, including shared resources, dynamic operating environments with migration and resizing of virtual machines (VMs), changing workloads, and more. Shared resources compete for cache, disk, and network resources, and there are challenges in distinguishing performance issues due to contention from application failures across several resources. There are dynamic challenges in di...
