State of a Synology NAS, by SNMP
Returns the state of a Synology NAS: its system partition, power supplies, fans and thermal state, its temperature, whether a DSM update is available, and its model and DSM version. Four watches are offered, each one set on the probe.
Versions
Generic: written for SYNOLOGY-SYSTEM-MIB as Synology's SNMP MIB guide describes it for DSM 6.2.4 and later, DSM UC and DSM Enterprise. An object a model does not serve is left out, so it stays at the common level.
How it works
The collector walks the branch 1.3.6.1.4.1.6574.1 once and reads:
| Object | OID suffix | Read as |
|---|---|---|
systemStatus | .1.0 | status of the component System partition |
temperature | .2.0 | temperature |
powerStatus | .3.0 | status of Power supplies |
systemFanStatus, cpuFanStatus | .4.1.0, .4.2.0 | status of System fan, CPU fan |
modelName, version | .5.1.0, .5.3.0 | model, version |
upgradeAvailable | .5.4.0 | update: available (1), unavailable (2), connecting (3), disconnected (4), others (5) |
thermalStatus | .8.0 | status of Thermal |
- A status is
normal(1) orfailed(2), as the MIB says. - A component whose object the agent does not serve is left out; a missing temperature, model or version stops the collector, rather than return a value that was not read.
- The collector only reads: SNMP sends nothing but reads.
Prerequisites
- The SNMP service of DSM enabled (Control Panel, Terminal & SNMP, SNMP), reachable from the poller (UDP 161), its access restricted to the poller.
- Read-only access, SNMPv2c or SNMPv3, set on the host or one of its folders (
protocol:snmp:*variables).
Outputs
| Name | Label | Unit | Per instance |
|---|---|---|---|
status | Status | — | yes, per component |
temperature | Temperature | °C | no |
update | DSM update | — | no |
model | Model | — | no |
version | DSM version | — | no |
Watches
| Name | Title | Kind | Defaults | Checked by default |
|---|---|---|---|---|
failed | Component failed | state to avoid, on status | critical on failed | yes |
hot | High temperature | above a threshold, on temperature | warning above 50 °C, critical above 60 °C, for 3 runs | yes |
update-available | DSM update available | state to avoid, on update | warning on available | no |
version | Unexpected DSM version | expected value, on version | no version given: it raises nothing until a version is set on the probe | no |
Limits
- An agent that serves no
systemStatus(not a Synology, or a view without1.3.6.1.4.1.6574) stops the collectormisconfigured. - The MIB guide gives no unit for the temperature: it is read as degrees Celsius, which DSM shows.
- Not checked against a Synology: the OIDs and values are those of Synology's SNMP MIB guide (last updated 2026-08-03).
