Troubleshooting Monitoring

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.
