I have created an improved version of the SNMP QNAP Template for Zabbix available on-line. This new template is still based on SNMP, but has the following features:

• Autodiscovery of Disks, Volumes, Network interfaces and Fans
• Numerical values stored as real number
• Triggers for multiple issues: lack of remaining disk space, hostname change, interface status change, reboot, high temperature, and cpu load too high
• Graphs for network traffic

To install the template, first create a Value mapping named “QNAP Drive Status” with the following values:

4=Unknown
5=No Disk
6=Invalid
9=Read/Write Error
0=Ready

Then import the improved QNAP template and apply it to your NAS. That's all.
