I'm sorry that nobody has so far responded to this question. I thought
this had long been taken care of :/

The list of counters of every program can be displayed/exported if you
enter "show asciidoc counters", which is what we use to generate the tables
you find in the manuals of the respective program.

To get some more background about the individual counter types:

* osmo_stat_item
  http://ftp.osmocom.org/api/latest/libosmocore/core/html/group__osmo__stat__item.html#details

* rate_counter
  http://ftp.osmocom.org/api/latest/libosmocore/core/html/group__rate__ctr.html#details

* osmo_counter (old, more or less deprecated)
  http://ftp.osmocom.org/api/latest/libosmocore/core/html/structosmo__counter.html

* osmo_stats_reporter
  http://ftp.osmocom.org/api/latest/libosmocore/core/html/group__stats.html#details

  We have two of those in libosmcoore: One that reports to the logging sub-system,
  and another one that reports to statsd / behaves like a statsd exporter

For rate counters, there's an example script on how to export them at
http://git.osmocom.org/python/osmo-python-tests/tree/scripts/osmo_rate_ctr2csv.py

If you have any more specific questions, please follow-up here. Thanks!

Regards,
	Harald
