Manually, Low Efficiency
Waste much time and manpower. Meanwhile mistake happens due to manually calculation.
Un-visualized, No Trend
Difficult to have a visualized view of the network performance status and to sense the changing trend.
Mass Data, Isolated Analysis
Hard to do correlated analysis among mass data in order to locate the problem.
