Zabbix agent not answering in Web UI than in Zabbix get ?

[Yannick038]

I setup a new host with agent configured.
Data is received but is inconsistent + incomplete in Web UI where as a zabbix_get on the zabbix server answer me correctly :

root@hzabbix:/home/debian $ zabbix_get -s <HOSTIP> -k net.tcp.service[ssh,,22]
1
root@hzabbix:/home/debian $ zabbix_get -s <HOSTIP>-k agent.version
3.2.4

but within web ui it is not displayed :

In the screenshoot you can see that agent.version is not answered not SSH service, although zabbix_get answers us correctly "1"

Found the answer :

The SSH element is of type "simple element"
Therefore the verification is done by trying to telnet to the SSH port from zabbix server

But on this particular server i have a firewall to limit SSH access > telnet is not allowed, zabbix server has been opened only on INPUT / 10050

Switch the SSH template from "simple element" to "zabbix agent" and you're ok !
