The eNB performance report generates a report of eNB performance in each layer and notes anything unusual in the results.
The performance report is based on the same KPI-related measurements that are reported to any remote monitoring system (Zabbix, for example).
Getting the Report
To generate a report:
enb measurements report
The report is based on performance since the measurements were last cleared. This period of time is shown in the report as the baseline, in seconds. To clear measurements and start a new baseline:
enb measurements clear
Note: This will also clear measurements reported to the remote monitoring system.
Reading the Report
The report shows, for each layer in UL and DL:
- packet loss (PDCP)
- transport blocks dropped due to late processing (MAC)
- mean transport block size and mean buffer status report (MAC)
- spectral efficiency in bits/element (PHY)
- total available traffic BW, excluding overhead, in kbits/sec (PHY).
The report also shows random access request (RAR) processing performance:
The report will also include “NOTE” comments drawing attention to possible performance problems.
(Because the baseline of this report is 8 seconds, the kBytes and kBit/sec figures match numerically.)
