You can also store the difference between 2 readings.  Otherwise your counters 
will increase forever.

You can try to redirect the ULOG to a named pipe or a shell script.  

Named pipe example :
mkfifo test
echo 1 > test &
echo 2 > test 1
echo 3 > test &
cat test
3
2
1
[1]   Done                    echo 1 >test
[2]-  Done                    echo 2 >test
[3]+  Done                    echo 3 >test

So the numbers 1, 2 and 3 were cached in the named pipe untill the cat command 
was executed.
