QNAP QTS / QuTS hero

Beta

This integration was built from the public references (the pages read by the Home Assistant qnap integration and the python-qnapstats library) and tested against recorded-style responses only, not against a real QNAP NAS yet. It only reads. Tell us what breaks.

A QNAP NAS through the CGI pages of its web interface: volumes that fill up, disks whose SMART health is no longer good or that run too hot, processor temperature, memory, and the QTS or QuTS hero updates QNAP offers.

QNAP publishes no documented REST API for the NAS status, so DumbMonit reads the same XML pages as the web interface and as the reference clients. Each minute it opens a session (POST /cgi-bin/authLogin.cgi, the password base64-encoded in the request body, never in the URL), reads, and closes the session (/cgi-bin/authLogout.cgi) even when a read failed: QTS limits the number of open sessions. The session identifier travels in the URL of the reads, so DumbMonit removes it from every error message.

One page is required — the system information (manaRequest.cgi?subfunc=sysinfo: processor, memory, temperatures, uptime) — and three are optional, left out without failing the rest when the account or the QTS version does not serve them: volumes (chartReq.cgi), disks and their SMART health (disk_manage.cgi), and the firmware update check (sysRequest.cgi).

The state of RAID groups (degraded, rebuilding) is not read: no reference client documents it.

Network ports to open

From the DumbMonit server (or its relay agent) to the device:

Port	Protocol	Purpose
443	TCP	Web interface (HTTPS, default)
8080	TCP	Only with the HTTP protocol option

What it watches

All metrics are prefixed dumbmonit_qnap_.

Metric	Labels	Meaning
version_info	version, build, model, hostname	Value 1.
cpu_usage_percent		Processor usage.
cpu_temperature_celsius, system_temperature_celsius		Processor and enclosure temperature.
memory_total_bytes, memory_used_percent		Memory.
uptime_seconds		Since the last boot.
volumes		Number of volumes.
volume_size_bytes, volume_free_bytes, volume_used_percent	volume	Per volume.
disks, disks_unhealthy		Disks present (empty bays are left out) and those whose SMART health is not good.
disk_ok	disk, model	1 when the SMART health is good.
disk_warning	disk, model	1 when it is a warning rather than a failure.
disk_temperature_celsius	disk, model	Disk temperature.
firmware_update_available		1 when QNAP offers a newer release.
firmware_latest_info	version	Value 1: that release.

The built-in rules that apply:

• QNAP volume nearly full: above 90 % for 30 minutes (Advisory).
• QNAP disk health not good: for 15 minutes (Advisory).
• QNAP disk too hot: above 55 °C for 15 minutes (Advisory).
• QNAP processor too hot: above 90 °C for 15 minutes (Advisory).
• QNAP firmware update: a release is offered (Info, reminded weekly).

The monitor page

The NAS panel says what is wrong in a sentence, shows processor, memory, temperature and uptime, then lists the volumes (the fullest first) and the disks with their SMART health and temperature.

Create a limited account for DumbMonit

1. Open Control Panel → Privilege → Users → Create → Create a User and create the account as follows, with a long random password. Tick no share and no application privilege.

   dumbmonit
   

2. Add the account to the administrators group: QTS serves the system status, volumes and disks to that group only.

3. Optional: under Control Panel → System → Security → Allow/Deny List, allow the web interface only from the DumbMonit server's address.

4. In DumbMonit, enter the NAS address (for example nas.lan) with that user name and password. Choose http and port 8080 only if HTTPS is off.

Required permissions

• administrators group — The only group QTS lets read the system status
• No share, no application privilege — Nothing else is needed

Warning

QTS has no read-only role for its system status, so the account sits in the administrators group: give it a unique password, and an account without 2-step verification. Over HTTP the password travels base64-encoded, not encrypted: prefer HTTPS.

Notes

• DumbMonit never writes: every call is a read, and the account has no share or application privilege.
• An account with 2-step verification cannot log in for a monitor: create a dedicated one without it.

Credentials

Credential	Fields
User name and password	The account created above.

Address: the host name or IP of the NAS, host:port, or a URL. Options:

• Protocol (https): http or https.
• Port (443): used if the address does not give a port; enter 8080 for HTTP, QTS does not use 80.
• Accept an unverifiable certificate: the NAS's own certificate is self-signed.
• Timeout per request (15 s).

Troubleshooting

"QNAP refused the login": wrong user name or password, or the account is disabled.

"The account uses 2-step verification": create a dedicated account without it.

"QNAP refused the session … the account may lack the right to read it": the account is not in the administrators group.

No disk or volume: those pages are optional and a QTS version may serve them differently; the rest is still read. Tell us your QTS version.
