amari.{kpi,drb}: Fix multicell handling (!7) · Merge requests · Kirill Smelkov / xlte

Merged Kirill Smelkov requested to merge y/multicell into master Nov 11, 2024

Fix amari.kpi to handle stats messages in enb.xlog that come with multiple cells. Previously such messages were leading to the following errors on KPI calculator place (e.g. Wendelin):
```
 xlte.amari.kpi.LogError: t1731059787.321: stats describes 2 cells;  but only single-cell configurations are supported
```
Fix amari.drb to generate x.drb_stats messages when an UE is associated to multiple cells due to e.g. Carrier Aggregation. Previously CA was leading to
```
 raise RuntimeError(("ue #%s belongs to %d cells;  "+
     "but only single-cell configurations are supported") % (ue_id, len(ju(['cells']))))
```
error on eNB side.

Please see individual patches for details.

An example enb.xlog for eNB with 2 cells and an UE Carrier-Aggregated to both cells is here:

And here is how it looks when visualized via kpidemo.py :
