Zabbix sender hostname domain ?

[system]

Zabbix sender fails when used with uname -n:

[root@host bin]# /usr/local/sbin/zabbix_sender -s `uname -n` -z zbxserver -k mykey -o `date +%s`
Info from server: Failed 1

Because uname returns hostname + domain :

[root@host bin]# uname -n
myhost.mydomain.fr

It works when specifying hostname without domain manually :

[root@host bin]# /usr/local/sbin/zabbix_sender -s myhost -z zbxserver -k mykey -o `date +%s`
Info from server: "Processed 1

In opposition to what the doc states, it does not work with IP :

[root@host bin]# /usr/local/sbin/zabbix_sender -s 10.0.13.19 -z zbxserver -k mykey -o `date +%s`
Info from server: "Failed 1

In Zabbix web interface, in hosts configuration, I tried to specify the domain, either in DNS, or in Name field. None solved the problem.

Do you have any idea ? Is it wrong to use uname in zabbix sender commands ? How would you make your scripts generic then ?

instead of uname -n use hostname -s

[system]

I thought of using hostname, but then I realized I could have several domains for one hostname...
webmail.mydomain.fr
webmail.myotherdomain.fr
...

Will Zabbix be able to distinguish where it comes from ?

The -s flag should match what Zabbix knows the system as, in my case these are short hostnames. In your case it appears that a fully qualified name is most appropriate, but it appears that Zabbix does not know your systems that way?

Thanks for your answers.
I'll make it with hostname -s, should be enough.
