Active Check problems with Zabbix 3.0.1

[cico_lt]

Hi,
I'm sorry for my bad English

I have Zabbix 3.0.1 on CentOS 7.2.1511.

I have some Active Item on a host. The web GUI says that those items are "Unsupported Item Key", but if I test each single Item on Zabbix Server, with command: zabbix_get -k <item_key> -s <ip_address>, the item works and return a value. Always.

Monitoring the zabbix server's log, I never see that the server tries to get a value from those items.

In the web GUI in the: Administration => General => Other => Refresh unsupported items (in sec), I set the value 10 .... then I expect that the Server tries to recover the Item....and instead... Nothing !!!

I tried also to disable for few minutes and then to Enable, the Items. But nothing again.

More informations are: the host to monitor is Enable; the zabbix agent is running on the host; the Unsupported Items are in a Template linked to the host.

Can someone help me, please ??

Thanks in advance

Hi,

- Does active items work in other hosts?
- Have you configured "ServerActive" and "Hostname" in zabbix_agentd.conf?
- Have you checked that your firewall is not blocking port 10051?
- Also you could try to increase the "DebugLevel" from the zabbix_agentd.conf file and see what it says.

Solved

Good morning,
thank you for the answer

I solved by myself, finally.

The problem was that ONLY in a host, items weren't correctly configured, while in the other hosts, they were configured. And so the GUI returned that the Items was "Not Supported" for ALL hosts ....

This is weird to me, but it is so.

Thank you again
