My custom settings for Zabbix Agents

Since some time ago, I’m used working with ZABBIX systems – as server as agent, proxy … . Now, I don’t going to explain all the fantastic features about this software in this post. In this post, I will only enumerate my preferred ZABBIX Agent settings and my best values for each one.

    No spaces allowed. First entry is used for sending active checks.
    Note that hostnames must resolve hostname->IP address and
    IP address->hostname.
