#### Overview

This section lists parameters supported in the Memcached Zabbix agent 2
plugin configuration file (memcached.conf). 

Note that:

-   The default values reflect process defaults, not the values in the
    shipped configuration files;
-   Zabbix supports configuration files only in UTF-8 encoding without
    [BOM](https://en.wikipedia.org/wiki/Byte_order_mark);
-   Comments starting with "\#" are only supported at the beginning of
    the line.
