How to visualise the traces?

[alchemist51]

Was trying to understand the flow of liquid cache today and saw that we do have spans and saw admin APIs for tracing.. Didn't find any document on how to visualise and general setup guidance. Probably we can add docs around it?

@XiangpengHao can you help with a general idea? I can try to raise documentation PR for it.

Sure, documentations are always welcomed!

There're basically two lines of observability: the open-telemetry and our own inhouse dashboard.

Both observability are best supported in client-server mode, i.e., not in in-process mode. but it would be great if we can apply them to in-process mode as well.

The open-telemetry setup can be found here: https://github.com/XiangpengHao/liquid-cache/tree/main/dev#observability

The dashboard can be found here: https://liquid-cache-admin.xiangpeng.systems, source code: https://github.com/XiangpengHao/liquid-cache-admin?tab=readme-ov-file

Basically when the liquid server is running, users can use the admin endpoint to connect to the dashboard.
