What to do with item which is shown in zabbix frontend like active, but in latest data I see very old value? When I try to telnet to zabbix_agent from zabbix_server with this key, I get right answer. Why there is not some error in web interface? How can I find if there is more items like this? Maybe it would be good to add some status page which can show which items are not refreshed ok ?
Thank you.
