    Available Memory on Zabbix Server 11G but top shows 11G in use

    I'm running Zabbix 2.4.2 and 2.4.8
    OS is Ubuntu 14.04
    Memory 12G
    I'm confused by the memory usage on the Zabbix server. When I look a the latest data for the zabbix server and under Memory, select Available Memory, it shows 11G (Available I assume) but when I ssh into the system, it shows 11G Used
