Plan:

Save with protobuffer.
Upload profiling data to server
Build a website to analyze profiling data. (Start with simple ones)

Backup plan: Use QT/python to visualize .

How to correlate multi-process data?

libHook.so request a unique id from the server
Send other profiling data with this id

GammaPi commented 2 years ago

How to aggregate multi-thread data?

Per-thread view
Correlate execution time with concurrent thread number (Needs full-record)
Lock view (Show lock relationship in a graph) (May not be scaler's current target)

GammaPi commented 2 years ago

Call graph does not have to be very specific. Show component-level information.
