Just applied the patch and it's perfect.

Please see below:

Great, at least that took care of that issue. As to missing output
from
one client, I've seen that here before, I will look into that. It's a
separate issue.

For the above one, s2 never started since it could not find the config
file you gave it. Have you seen missing final output for cases where
the jobs did all start? This particular one does not look valid.

Yes. I did.

I ran using both servers but the output was showing the latest client -
s2

Odd. Can you reproduce and send the output of such a run?

Hi Jens,

This is neto from Brazil

How are you?

I believe the issue could be formatting....

Also, when running from both clients, seem to me unified_rw_reporting is
not working... I do not have the total for all clients....

unified_rw_reporting groups reads, writes, and discards into the same
reporting bucket. I'm assuming you mean that group_reporting doesn't
work for multiple connections? That's the option that groups multiple
jobs together for reporting. And yes, that's not supported right now for
multiple connections. But it could be, it's not that different from the
ETA which is grouped as it would be on a local run.

Try newest -git. It now outputs an "All clients" summed section, if you have more than 1 client.
