PRTG Manual: SNMP Synology System Health Sensor
The SNMP Synology System Health sensor monitors the system health of a Synology network-attached storage (NAS) via the Simple Network Management Protocol (SNMP).
For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.
- Dutch: SNMP-Synology Systeemstatus
- French: Synology état du système (SNMP)
- German: SNMP Synology Systemzustand
- Japanese: SNMP Synology システム正常性
- Portuguese: Saúde do sistema Synology (SNMP)
- Russian: Работоспособность системы Synology по SNMP

Consider the following remarks and requirements for this sensor:
Remark |
Description |
---|---|
IPv6 |
This sensor supports IPv6. |
Performance impact |
This sensor has a very low performance impact. |
Lookups |
This sensor uses lookups to determine the status values of one or more channels. |
Knowledge Base |
Knowledge Base: Why does my Synology System Health sensor show incorrect CPU and memory values? |
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- snmpsynology
- synology
- systemhealth
For more information about basic sensor settings, see section Sensor Settings.

Primary Channel |
Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel below the sensor's name. The available options depend on what channels are available for this sensor. You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab. |
Graph Type |
Define how this sensor shows different channels:
|
Stack Unit |
This setting is only visible if you select Stack channels on top of each other above. Select a unit from the list. PRTG stacks all channels with this unit on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so. |
By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click under the corresponding setting name to disable the inheritance and to display its options.
For more information, see section Inheritance of Settings.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.

CPU Load |
The CPU load (%) For more information about the shown memory and CPU load values, see the Knowledge Base: Why does my Synology System Health sensor show incorrect CPU and memory values? |
Downtime |
In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status |
