This is a simple setup, one zabbix server and a couple of server with zabbix client, A POC setup to see if zabbix is usable for us. We want to aggregate the total number of an item for all hosts in a host group. But the zabbox_aggregate agent is failing with above message. Our setup looks like this:

1) agent file at each host :
cat /etc/zabbix/zabbix_agentd.conf

1. This is a config file for the Zabbix agent daemon (Unix)
