Add Check dialog for the QNAP NAS check, scrolled to the threshold section showing CPU Thresholds (Warning 80 %, Critical 95 %), Temperature Thresholds (Warning 50 °C, Critical 60 °C), and Volume Thresholds, with the Add Check confirm button outlined in red at the bottom.

A QNAP Check monitors QNAP NAS devices via SNMP — disk health (including per-disk SMART status), volume usage, temperature, CPU load, and fan status. It gives you early warning of storage problems on your QNAP devices.

Prerequisites

  • You need the Monitoring Check Management permission.
  • The target device must have a connected agent with network access to the NAS.
  • The QNAP NAS must have SNMP enabled with a known community string.

Steps

  1. Go to Devices and open the device that has network access to the QNAP NAS.
  2. Click the Checks tab → Add Check → QNAP NAS.
  3. Enter the NAS hostname or IP address in the Host field, and the community string under SNMP Community (default: public). The SNMP version defaults to v2c; for SNMPv3 settings, see the QNAP Check Reference linked below.
  4. Configure the thresholds:
FieldDefaultDescription
Volume usage — Warning80 %Warns if a volume exceeds this usage
Volume usage — Critical90 %Critical if usage exceeds this value
CPU usage — Warning80 %Warns if CPU usage exceeds this value
CPU usage — Critical95 %Critical if CPU usage exceeds this value
System temperature — Warning50 °CWarns if system temperature exceeds this value
System temperature — Critical60 °CCritical if temperature exceeds this value
Disk temperature — Warning45 °CWarns if a disk temperature exceeds this value
Disk temperature — Critical55 °CCritical if disk temperature exceeds this value
  1. Click Add Check.

Tips

  • SNMP must be enabled on the NAS itself before octoja can query it — enable it in the QNAP QTS Control Panel and use at least SNMPv2c with a community string that matches what you enter above. See QNAP's SNMP documentation for the exact steps on your QTS version.
  • Set volume usage thresholds based on your capacity planning — NAS performance degrades significantly above 90% usage.
  • This check covers hardware health. For file-level monitoring (backup freshness), use the File Age check.

After the first check interval, the result appears in the device's Checks tab.
