I am running cprof to find bottlenecks, but I get a lot of dots in the output. Does someone have an idea how I can get the data instead, or why the dots are shown?

example:

Quote:
{mnesia_tm,607905,
[{{mnesia_tm,do_arrange,...},396910},
{{mnesia_tm,...},18792},
{{...},...},
{...}|...]},
{yaws,575055,[{{yaws,...},178266},{{...},...},{...}|...]},
{erlsom_parse,458841,[{{...},...},{...}|...]},
{xmerl_scan,444140,[{...}|...]},
{file,414660,[...]},

The shell process reduced the ammount of data to display with dots, so as to not clutter the output. (A list could have thousands of elements. You do not always want to show them all). To see everything, you need to bind the return value to a variable and print it using ~p.:

Code:
X = mnesia:your_call().
io:format("~p~n",[X]).
