iManager: Bring you efficient O&M in E2E network lifecycle 7 Steps to Know iManager 】Step.2: Performance report system: PRS
Manually, Low Efficiency Generating Reports
Mass Data, Isolated Analysis Hard to do correlated analysis among mass data in order to locate the problem.
Waste much time and manpower. Meanwhile mistake happens due to manually calculation.
Manage Network Performance Troubleshooting
Un-visualized, No Trend Monitoring
Difficult to have a visualized view of the network performance status and to sense the changing trend.
