That's not how systemtap/dtrace work; the process itself doesn't "see"
the probe results, only the tracing app (and only when tracing is on).
Instrumenting in-process is rather harder IMO as the server has to keep
track of the data, process it and changing the way it presents the data
(e.g. EWMA versus histogram versus...) requires source-code changes.
