Method and system for supporting network system troubleshooting

A system for supporting network troubleshooting, comprising:

• storage means for periodically storing setting/configuration data which includes
• physical location information and building work information, and performance data of devices constituting the network based upon a schema of device IDs, interface IDs, and a respective CONFIG version number thereby correlating said setting/configuration data with said performance data;
• monitoring means for monitoring the performance data of the devices by comparing the performance data with respective threshold values;
• identifying means for identifying the faulty device based upon the schema, when the performance data of at least one device goes beyond a respective threshold value (“faulty device”), wherein
• the storage means further stores the identified result for network troubleshooting.

An operation data managing method for a network system, comprising:

• establishing a data management schema of the network system based upon components of the network, relation between the components, and operation data associated with the components;
• periodically storing the operation information based upon the schema and a respective CONFIG version number;
• and
• selectively extracting at least one of the components and associated operation data using the CONFIG version as a linking key, wherein
• the operation data include setting/configuration data which includes physical location information and building work information, and performance data of the components thereby correlating said setting/configuration data with said performance data.
