Add tracer to record configured events to database This extends the functionality provided by record in that it allows collection of data into a Clickhouse database, allowing aggregation of data from gNB and UE for functions like channel estimation for PUSCH transmissions that did not decode successfully at the gNB. It is intended to be used in conjunction with Aerial Data Lake but is not limited to it. Data access is simpler than in !3462 (merged), but could be improved using the metadata approach from !3462 (merged). Usage is similar to the exsting record tracer: docker exec -it oai-nr-ue bash -c "record_db -on UE -off VCD -ch-droptables -off UE_PHY_UL_TICK -off UE_PHY_DL_TICK -off UE_PHY_PDSCH_IQ" Which outputs recorded data every 5 seconds: 17:35:40.945037 record_db.cpp:570 INF[main ] Initialized buffer for event_id:21 name:UE_PHY_INITIATE_RA_PROCEDURE has_frame_slot:false columns:5 17:35:40.945924

How to get support from the OAI Community
You can ask your question on the mailing lists.
Your email should contain below information:
- A clear subject in your email.
- For all the queries there should be [Query] in the subject of the email and for problems there should be [Problem].
- In case of a problem, add a small description.
- Do not share any photos unless you want to share a diagram.
- OAI gNB/DU/CU/CU-CP/CU-UP configuration file in
.confformat only. - Logs of OAI gNB/DU/CU/CU-CP/CU-UP in
.logor.txtformat only. - In case your question is related to performance, include a small description of the machine (Operating System, Kernel version, CPU, RAM and networking card) and diagram of your testing environment.
- Known/open issues are present on GitLab, so keep checking.
Always remember a structured email will help us understand your issues quickly.
