My Zabbix instance has basic item keys that are returning "Unsupported Key item: for some servers, but not for others. The one key that sticks out:
Name Key Type NTP running? net.udp.service[ntp] Zabbix Agent(active)
Of course, when I ssh to the server, ntp is running. Is there a way to find out why exactly it is not supported?
Zabbix Agents are Ubuntu 14.04 and 16.04 Zabbix 3.4 Zabbix Server is Ubuntu 16.04 and Zabbix 3.4
