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

Physical Cell Identifier

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)
