Key performance indicators (KPIs) indicate the performance of a running device at a specific time. A KPI may be obtained by aggregating multiple levels of KPIs. The KPI data collected by the main control board and interface boards is saved as an xxx.dat file and stored into the CF card on the main control board. The KPI parsing tool parses the file according to a predefined parsing format and converts it into an Excel file. The Excel file provides relevant fault and service impairment information, facilitating fault locating.
The KPI system records key device KPIs in real time, provides service impairment information (for example, the fault generation time, service impairment scope/type, relevant operation, and possible fault cause/location), and supports fast fault locating.
The KPI system helps carriers quickly learn service impairment information and locate faults, so that they can effectively improve network maintainability and reduce maintenance costs.
