yes, you can:

5> folsom_metrics:new_counter(<<"test.0">>).
6> folsom_metrics:notify(<<"test.0">>, {inc, 1}).
7> folsom_metrics:notify(<<"test.0">>, {inc, 1}).
8> folsom_metrics:notify(<<"test.0">>, {inc, 1}).
9> folsom_metrics:get_metric_value(<<"test.0">>).          3

10> folsom_metrics:new_counter(<<"test.0">>).
{error,<<"test.0">>,metric_already_exists}

11> folsom_metrics:get_metric_value(<<"test.0">>).
3

so if you know how to identify your clients it is pretty easy to collect
the stats

with graphite you can qury for "test.*" to get all the counts

You can do pretty much teh same thing with exometer.

Cheers,
Alex.
