session_log does not contain Statistics information

[chutoutian]

Hi I am using ALVR20.11.1 and I want to use the history statistics like latency and bitrate but the logs say:

11:41:31.230 INFO Client 8428.client: [Warning] Statistics summary not ready!

And the [STATS] and [GRAPH] are empty:

11:41:37.946 [STATS]
11:41:37.946 [TRACKING] {"device_motions":[["/user/hand/left",{"pose":{"orientation":[-0.05758141,0.21218827,0.33082303,-0.91772366],"position":[-0.30668914,0.6977202,-0.86611617]},"linear_velocity":[0.0,0.0,0.0],"angular_velocity":[0.0,0.0,0.0]}],["/user/hand/right",{"pose":{"orientation":[-0.16810232,-0.2498652,-0.524207,-0.7965652],"position":[0.017634995,0.57615304,-0.29410082]},"linear_velocity":[0.0,0.0,0.0],"angular_velocity":[0.0,0.0,0.0]}],["/user/head",{"pose":{"orientation":[0.03658971,0.18495813,0.03534971,0.9814287],"position":[0.024379883,1.0507616,-0.18076341]},"linear_velocity":[0.0,0.0,0.0],"angular_velocity":[0.0,0.0,0.0]}]],"hand_skeletons":[null,null],"eye_gazes":[null,null],"fb_face_expression":null,"htc_eye_expression":null,"htc_lip_expression":null}
11:41:37.946 [GRAPH]

Are there some configurations I missed?

Thanks

Oh I did not fully realized i did that. But at the same time, I this that's fine. statistics are quite spammy and it would be better to leave it out of logging. logs are meant to be human readable, and a bunch of floating point values are not easy to understand. if you intend to use the statistics data you should instead subscribe to the events websocket at ws://localhost:8082/api/events

Hi, thanks. I got the wanted statistics. BTW, current logs still contain the user's pose data which has a similar format to the statistics. But anyway, thanks~~

You're right. That should be more consistent

Tbh I don't think so. Logging is a huge mess and intentionally introducing spam is seems like a bad idea even if we have the log enabling disabling choices. It seems good as is as the statistics information are already accessible for debugging.
For the future, if anything, I'd say to also externalize pose information if that can be done in an easily accessible way (maybe wmr already)

Especially because actually structured information is way more useful than trying to parse info from text logs
