There is also this old module, stats.yaws that's been lying around
for quite some time. I can't find it in the git repo though - unclear
why it's gone - maybe superseded by yaws --stats, I don't know.
The heart is yaws_server:stats() which can be used in various ways.
# cat /usr/local/var/yaws/www/stats.yaws
<erl>
out(A) ->
yaws_api:ssi(A#arg.docroot, ["/HEAD", "/TOPTAB"]).
</erl>
<erl>
out(A) ->
{UpTime, L} = yaws_server:stats(),
{Days, {Hours, Minutes, Secs}} = UpTime,
H = f("<html> ~n <h4>Uptime: ~w Days, ~w Hours, ~w Minutes </h4> ~n",
[Days, Hours, Minutes]),
T =lists:map(
fun({Host,IP,Hits}) ->
L1= f("<hr \><h3> stats for ~p at ~p </h3>~n",
[Host,IP]),
T = "<table border=\"2\" > \n"
"<TR> <TH>URL</TH> <TH>Number of hits</TH> </TR>",
{L2, Total}=lists:mapfoldl(
fun({Url, Hits}, Sum) ->
{f("<TR> <TD>~s</TD> <TD>~w</TD> </TR>~n",
[Url, Hits]), Sum + Hits}
end, 0, Hits),
END = f("<TR><TH>Total</TH><TH>~w</TH><TR></table>", [Total]),
[L1, T, L2, END]
end, L),
{html, [H, T]}.
</erl>
<hr \>
</td>
</table>
</html>

There can be several yaws nodes running on the same host
and under different users.
the error above, indicates that root is not running any
yaws servers with id=default, try
# yaws --ls
The file $HOME/.yaws is used to hold info on which
socket to connect to in order to control yaws - for that user.

Maybe some sudo issue, you're root but $HOME is not
set accordingly
[klacke@kisel]~ > sudo echo $HOME
/home/klacke
[klacke@kisel]~ > sudo -s -H 'echo $HOME'
/root
The above is an indication of that

Uhhh - I'm forgetting how my own webserver works - slap on forehead.
In embedded mode - all the yaws ctl functions are disabled. The idea
being that if yaws runs in embedded mode, the surrounding app has it's
own ctl stop,start,stats functions.
Typically, if you embed yaws, you don't want it to write random files
in $HOME. I guess it would be easy to circumvent this though if the yaws ctl
functions really is what you want for for your app.
