Hello.
I have a problem with the 2.0.4 version of zabbix_sender. When i use it
with stdout on terminal, it returns "info from server":

1. ./zabbix_sender -z zabbix_server -i /var/run/zabbix/cache.nmon 2>&1
   info from server: "Processed 12 Failed 0 Total 12 Seconds spent 0.000201"
   sent: 12; skipped: 0; total: 12

But when stdout is redirected, no info from server appears:

1. ./zabbix_sender -z zabbix_server -i /var/run/zabbix/cache.nmon
   2>&1 | cat
   sent: 12; skipped: 0; total: 12

Our scripts are dependent on this info (especially Failed count). Is
there any other way to get information about failed keys in sending session?
Or isn't it a bug?
When I include an invalid key in the file, responses are as follows:

1. ./zabbix_sender -z zabbix_server -i /var/run/zabbix/cache.nmon 2>&1
   info from server: "Processed 12 Failed 1 Total 13 Seconds spent 0.000205"
   sent: 13; skipped: 0; total: 13

1. ./zabbix_sender -z zabbix_server -i /var/run/zabbix/cache.nmon
   2>&1 | cat
   sent: 13; skipped: 0; total: 13

In the latter case I have no information about failing key. Return value
is still 0.

Thank you.
