Category: Disk and Storage Health Monitoring

Description: Monitors disk drive health via smartmontools SMART attribute reporting, failure predictions, and self-test results.

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 SMARTD-MIB?

SMARTD-MIB is the SNMP MIB shipped with smartmontools' smartd daemon, a vendor-neutral open-source tool that monitors ATA/SCSI hard disk and SSD health via the SMART (Self-Monitoring, Analysis and Reporting Technology) standard, exposed on any Linux/Unix host running the daemon. It exposes general agent configuration, such as software/OS/hardware versions, monitoring mode, and network/connect settings, alongside per-device SMART data reachable through its device table, covering drive identification and health/failure predictions. It is explicitly a hardware/software health-monitoring MIB: it surfaces disk drive predictive-failure status and SMART results so an admin can catch a failing disk before it causes an outage, alongside the smartd agent's own software version and last-configuration-change timestamp. It stands alone as a vendor-neutral MIB tied only to the smartmontools software rather than any hardware vendor's proprietary framework, though it's commonly polled alongside HOST-RESOURCES-MIB or vendor storage MIBs for a fuller picture of a server's disk subsystem. It is deployed on any server, NAS, or storage node running smartd with SNMP support enabled, typically as part of a broader disk-health/predictive-failure monitoring strategy. Engineers implementing or auditing this functionality typically reference the SMARTD-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in SMARTD-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

  • Any server/NAS/workstation running smartmontools' smartd (vendor-neutral)
  • SATA/SAS/SCSI hard disk or SSD storage

Monitoring Examples

An admin would walk smartDevices to enumerate monitored drives and check each entry's SMART health status for a predictive-failure flag, while smartGenLastChange and smartGenMonitorMode confirm the daemon's polling configuration hasn't drifted; a device reporting an imminent-failure attribute is a clear signal to schedule disk replacement before data loss. smartGenSWVersion and smartGenHardwareVersion are also useful to confirm the monitoring agent itself is running a supported build after an OS upgrade.

What Can Be Monitored

  • disk SMART health/failure status
  • monitored device inventory
  • smartd agent software/hardware version
  • monitoring mode and polling configuration
  • last configuration change time
