If anyone has had any success using the tracing themselves (or got
stuck), let me know!
Is this:
```
let () =
let trace_pages = MProf_xen.make_shared_buffer ~size:1000000 in
let buffer = trace_pages |> Io_page.to_cstruct |> Cstruct.to_bigarray in
let trace_config = MProf.Trace.Control.make buffer MProf_xen.timestamper in
MProf.Trace.Control.start trace_config
```
really sufficient to get a shared buffer? Running a unikernel with the above code
(+ some calls to MProf.Counter.increase for data), `xenstore-list` doesn't show
anything in /local/domain/domid_number/data , but it looks like that's where the
`collect` code expects to find memory to dump.
Please let me know what extremely obvious thing I have overlooked :)
Thanks,
Mindy
