Error on discovery (Not supported item)

[Merrick]

Hello everybody,

first of all, english is not my native language, so please forgive me if I make mistakes.
I'm using zabbix server v4.4.2 (docker) :

I use zabbix agent v 4.4.2

I try to use fail2ban (https://share.zabbix.com/cat-app/firewall/fail2ban) and systemd (https://share.zabbix.com/operating-s...ice-monitoring), and I must say it works for several agents. But on one, it doesn't work, with the message Unsupported item key.
When I go on the serveur and launch zabbix_get, I have information :

[FONT="Open Sans"]root@4710b6763d8d:/var/lib/zabbix# zabbix_get -s ht1.xxxxx.net -k systemd.service.discovery[/FONT]  {"data":[{"{#SERVICE}": "service1"},{"{#SERVICE}": "service2"},{"{#SERVICE}": "service3"},{"{#SERVICE}": "service4"},{"{#SERVICE}": "service5"},{"{#SERVICE}": "service6"},{"{#SERVICE}": "sshd"},{"{#SERVICE}": "unionfs"}]}

root@4710b6763d8d:/var/lib/zabbix# zabbix_get -s ht1.xxxxx.net -k fail2ban.status['sshd']
6

On the server, all logs I see is

169:20191127:110111.068 discovery rule "ht1.xxxxx.net:fail2ban.discovery" became not supported: Unsupported item key.

Can someone help me on that ?

Sorry, I found the issue : the agent was auto registrated via discovery, with the wrong IP (172.18.x.x). I put the right IP and now it works fine, can someone close this topic ?
