Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings. In the accompanying drawings: FIG. 1 is a schematic diagram of a fault diagnosis system implementing the present invention. The system deploys probes on the probe station, observes the status of the probes, and performs fault detection and diagnosis. The fault management system includes a probe, a management host, an interface module, a management / information presentation module, a fault detection module, a fault diagnosis module, a dependency model memory, an effective probe information memory, and an alarm / fault information memory.

[0026] A probe is a service session deployed on a user host or a dedicated test host. When running, it can monitor the service performance obtained at its location and report performance parameters to the interface module. The management host can access the required data through the interface module and control the operation of t...

Abstract

The invention discloses a service fault diagnosis system and a method based on an active probe. The invention uses the active probe to effectively monitor the service performances in the network, so as to ensure the performances of using service of all the parts which are accessed in the network; when the invention discovers the abnormality by monitoring, the invention can rapidly and accurately position the source of fault according to the monitored symptoms. The invention has small cost of the monitoring and good fault diagnosis performance, at the same time, the invention selects the probe based on the uncertainty model, which can ensure the detection rate of each fault by smaller probe cost and obtain the good diagnosis performance.

Description

technical field [0001] The invention relates to the field of service fault management, in particular to an active probe-based service fault diagnosis system and method thereof. Background technique [0002] Fault diagnosis needs to use certain algorithms to draw fault assumptions based on the symptoms obtained from fault monitoring. Fault monitoring techniques can be divided into passive and active. Passive monitoring technology uses a large number of monitoring facilities to monitor existing service sessions. It is generally based on service client monitoring or network data packet collection and request-response reconstruction. If abnormalities are found, an alarm will be sent to notify the management system. Active monitoring technology sends probes to services from specific points to obtain application-level performance. A probe can monitor the performance of one or more system components, and the status of the monitored components can be judged based on the return valu...
