Metrics are generated once per second by default. This can be configured using the expert.metrics_period_secs parameter in enb.conf
.
Metrics are provided on a per-UE basis for the downlink (DL) and uplink (UL) respectively. The following metrics are provided:
- rat
The RAT being used, either NR or LTE
- pci
- rnti
Radio Network Temporary Identifier (UE identifier)
- cqi
Channel Quality Indicator reported by the UE (1-15)
- ri
Rank Indicator reported by the UE (dB)
- mcs
Modulation and coding scheme (0-28)
- brate
Bitrate (bits/sec)
- ok
Number of packets successfully sent
- nok
Number of packets dropped
- (%)
% of packets dropped
- pusch
PUSCH SNIR (Signal-to-Interference-plus-Noise Ratio)
- pucch
PUCCH SNIR
- phr
Power Headroom (dB)
- bsr
Buffer Status Report - data waiting to be transmitted as reported by the UE (bytes)
