Zabbix SNMP Template for (Western Digital) WD My Cloud EX4

In WD My Cloud EX4 is simple (MIBs here http://downloads.wdc.com/nas/WDMYCLOUDEX4-MIB.txt). 

Because some OID return not-clear-byte values (150.3G, 2.3T) - in items used "regex-magic". Loosing some precision (i try to beat this problem), for flexiable data:

Prerequisites:

• Enable SNMP on WD My Cloud EX4
• Zabbix 3.4+ with preproccessing support for regex-magic on item

Feautres:

Low Level Discovery:

•  physical disks 
•  logical disks
•  UPS

Notice:

In my env this NAS is "lazy" and have problems with BULK SNMP queries from Zabbix.

Template uses vars set on host-level:

• {$SNMP_PORT}
• {$SNMP_COMMUNITY}
