-------------------------------------------
A bit more notes about. Typo is indeed a mistake, I fixed it, but the real
origin of this logs records is in something different. Here is the sample
output from {{make check}}:

While I'd fixed the {{map_docs}} name, metrics are still unknown. This happens
because {{couch_stats}} didn't loaded
{{couch_mrview/priv/stats_descriptions.cfg}}. And this only happens if
{{couch_mrview}} application didn't ever be started. From
{{couch_stats/couch_stats_aggregator}}:
{code}
load_metrics_for_applications() ->
Apps = [element(1, A) || A <- application:loaded_applications()],
lists:foldl(
fun(AppName, Acc) ->
case load_metrics_for_application(AppName) of
error -> Acc;
Descriptions -> Descriptions ++ Acc
end
end,
[],
Apps
).
load_metrics_for_application(AppName) ->
case code:priv_dir(AppName) of
{error, _Error} ->
error;
Dir ->
case file:consult(Dir ++ "/stats_descriptions.cfg") of
{ok, Descriptions} ->
Descriptions;
{error, _Error} ->
error
end
end.
