See my other response.

The problem is that this appears to have zero documentation beyond the API
reference of libosmocore, which I pointed out in my other response on this
thread.  What we need is a section in the "common" part of the manuals explainig
this mechanism in detail.  I created https://osmocom.org/issues/3768 for this.

This also brings me to http://osmocom.org/issues/3670 "TTCN-3 test for statsd exporter"
which are missing so far.

Finally, https://media.ccc.de/v/SE8HRK is a talk by daniel on the related features
which may help as background information.

Any volunteers?  Seems like a very important topic operationally, but nothing
anyone has been contributing any effort towards so far :/

Regards,
	Harald
