Plugin not recognize memcached

Hi,

So, I have memcached installed and active as see:

[root@sev ~]# systemctl status memcached
● memcached.service - Memcached
   Loaded: loaded (/usr/lib/systemd/system/memcached.service; enabled; vendor preset: disabled)
   Active: active (running) since Sun 2018-12-23 02:09:42 EST; 2min 23s ago
