Metrics are generated once per second by default. This can be configured using the expert.metrics_period_secs parameter in ue.conf.

Metrics are provided for the received signal (Signal), downlink (DL) and uplink (UL) respectively. The following metrics are provided:

cc:Component carrier
rsrp:Reference Signal Receive Power (dBm)
pl:Pathloss (dB)
cfo:Carrier Frequency Offset (Hz)
mcs:Modulation and coding scheme (0-28)
snr:Signal-to-Noise Ratio (dB)
turbo:Average number of turbo decoder iterations
brate:Bitrate (bits/sec)
bler:Block error rate
ta_us:Time advance (uS)
buff:Uplink buffer status - data waiting to be transmitted (bytes)
