If you're looking for the drops as a function of time, you could do
something like this:
# dtrace -n 'BEGIN{start=timestamp;} mib:::udpInOverflows{@ =
lquantize((timestamp-start)/1000000000,0,10);}'
That will generate a histogram of the number of overflows each second
for the first 10 seconds that it runs (and puts all the rest into a
">10" bucket if run longer). Hit ^C to print the data. (It won't print
anything, though, if no drops occur.)
You can get a similar result with:
% netstat -s -i 1 | grep udpInOverflows
