Welcome to O-RAN SC KPI Monitoring Documentation¶
KPI Monitoring Overview¶
LTE eNB and 5G NR gNB produce data that can be monitored and analyzed to measure the system’s effectiveness. The near Real-Time RIC can gather the radio and system Key Performance Indicators (KPI) from E2 Nodes and can utilize the metrics for closed-loop control. The KPI includes but not limited following; UE measurement, E2 Node Measurement, E2 Node Load-related measurement. The KPIMON xApp provides the first step towards the successful closed-loop control, through the monitoring E2 Node’s performance metrics, and writing it into Redis DB. With the near real-time reporting KPIs, the near Real-Time RIC can immediately control E2 Nodes.
