Setup Zabbix with already existing Traefik container and Domain

[searchmyaim82]

Hello,

i have a ubuntu server, there are already running to other applications which are using traefik. (Just traefik labels in docker compose):

This is my bookstack application which is working:
labels:
traefik.enable: "true"
traefik.docker.network:...

[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.mydo
