To timestamp an event, use `LOGT("msg")` in c++ code or `cloudlog.timestamp("msg")` in python code. If the print is warning for frameId assignment ambiguity, use `LOGT(frameId ,"msg")`.
## Examples
Plotting with relative starts each process at time=0 and gives a nice overview. Timestamps are visualized as diamonds. The opacity allows for visualization of overlapping services.
