Hi, some items dalay more than others to be show in Front End.
Can click over the item, open Configuration and use Test button to know if it's working or have an error. If you get an error of permissions, need to solve it on O.S level.

Hi,

Test Button appears is disabled

You're using Zabbix Agent (Active) item. So it just can't be tested, 'cuz it's a Client>Server connection, need to check Client (Agent side) log file to understand why. FrontEnd simply can't enable Test button.

Other item types can be tested this way, even Zabbix Agent (Passive) check (Server>Client connection), basicaly every type of item that can be "controlled" in Server/Proxy (Server side), can be tested...

Hi,

log is that, only strange thing is "active checks on start enabled: false" for any plugin. The client/server comunication is ok, becouse all data are coming

Should have lines of sent information from Agent to Server/Proxy, or fail attempts (If all configuration is right, and your network isen't blocking anything).

One other debug you can do, is; use zabbix-sender, with an command like:
zabbix_sender -z SERVERorPRXAddress -s "Test" -k key.name -o "Value"

Must match key.name and type of value, it will returns more detailed information by this communication you're trying to do.

Some tests from agent, to see if ports are open

telnet localhost 10050 (Must stablish connection to itself)

netstat -tunpl | grep zabbix (Must show stablished connections)

Try from server/proxy to Agent

telnet AgentAddress 10050 (Must stablish connection to Client (Agent))
