Description: Monitors Synology NAS system health including CPU, memory, fan speed, and temperature.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is SYNOLOGY-SYSTEM-MIB?

SYNOLOGY-SYSTEM-MIB is a Synology proprietary MIB (enterprise OID 6574) reporting overall system health on Synology NAS appliances. Its objects cover system status, temperature, power status, system and CPU fan status, model name, serial number, DSM (DiskStation Manager) version, and an upgrade-available flag. As a hardware/software-status MIB it lets an administrator watch a Synology NAS's temperature and fan status, and know when a DSM update is available. It is deployed on Synology NAS appliances. Engineers can download the SYNOLOGY-SYSTEM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SYNOLOGY-SYSTEM-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Synology NAS appliances

Monitoring Examples

An administrator monitors temperature and systemFanStatus together to catch a Synology NAS overheating due to a failing fan before it triggers a thermal shutdown.

How to Use in IPNetwork Monitor

Example using systemStatus OID:

Select a Synology NAS appliance (temperature/fan/power/DSM-version system status) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type systemStatus into the Find box to locate it in the OID tree, then select it and click OK. It reports the synology system status Each meanings of status represented describe below. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
