NexRAN DL_Bytes and DL_PRB

[Joshua Moore]

Hello. I have used the NexRAN slicing xApp to collect KPI reports which i used Iperf3 to generate traffic at 20 Mbps in the DL. Whenever i look at the rows of collected data i do not understand the DL_Bytes value which is in the millions (13) and DL_PRB which is around 1400. I have looked through the srslte-e2 and nexRAN code without luck in understanding.

BR,

Joshua

Hi Joshua,
The values are accumulated over the entire duration of the KPM report period, i.e., the total amount of DL_byte and DL_PRBS for 5120 ms, if this period is configured.
Please have a look at these functions:  
Directory: srsenb/src/ric/e2sm_kpm.cc
void slice_metrics::update(metrics *m,std::map<std::string,std::vector<uint16_t>> slice_map)
void metrics::update(srsenb::enb_metrics_t *em)
Regards

Amjed
