Hi,
I have being try to track down top email users to sometime. When I do a network traffic check I can see there is about 15 times more email traffic pulled from mail server than sent.
The problem I am trying to track down is which users are the culprit.
I have enabled doevcot stats and I can do a doveadm stats dump user but I get a 0 for disk_input, disk_output, read_bytes and write_bytes. I do get mail_read_bytes numbers but I am not sure these numbers are correct.
I there a top utility that works well so I can see email traffic from users mailboxes. The doveadm top does not work well. I also tried the perl scripts and that does not do a much better job.
Thanks Kilburn

my stats contain numbers greater than zero, except for very few users.
Did you tested it with some account and waited a bit, incl. logins/logouts?

-- Steffen Kaiser Yes I waited more than 24 hrs but I would assume it would a few minutes would do it as well. I am using gentoo and dovecot 2.2.19. I get numbers for all columns except disk_input, disk_output, read_count, read_bytes, write_count and write_bytes which is 0.
cat /proc/self/io rchar: 2068 wchar: 0 syscr: 6 syscw: 0 read_bytes: 0 write_bytes: 0 cancelled_write_bytes: 0
Is this a kernel setting that causes this read_bytes and write_bytes to be 0 as it happens on a test server as well.
