Description: Defines SNIA Storage Management Initiative logging objects for storage subsystem event recording and auditing.

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 SNIA-SML-MIB?

SNIA-SML-MIB is a vendor-neutral MIB defined by the Storage Networking Industry Association (SNIA) as part of the Storage Management Initiative, used for logging events in storage subsystems. It exposes identity and asset data (product name/vendor/version, chassis manufacturer/model/serial number) alongside physical security status such as lock presence and security breach indicators. Its monitoring value centers on hardware/asset and fault status of the storage chassis: administrators use it to confirm device identity and detect a physical security breach (e.g., chassis intrusion) or missing lock, functioning as tamper/fault indicators rather than performance counters. It explicitly depends on the DMTF CIM (Common Information Model) schema, as reflected in smlCimVersion, layering SNMP objects over CIM-modeled storage management data. It is deployed in SAN and storage subsystem environments implementing the SNIA SMI-S logging specification for auditing and asset tracking, and administrators often consult a SNIA-SML-MIB reference when correlating these objects to the underlying CIM schema.

IPNetwork Monitor allows you to monitor SNMP objects defined in SNIA-SML-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

  • vendor-neutral, standards-based MIB (SNIA SMI-S), not tied to a specific manufacturer -- applies to SAN storage subsystems/enclosures

Monitoring Examples

An admin would read chassis-SecurityBreach and chassis-LockPresent to detect unauthorized physical access to a storage enclosure, and cross-reference product-Vendor/product-Version with chassis-Manufacturer/chassis-Model/chassis-SerialNumber to confirm asset inventory accuracy. smlMibVersion and smlCimVersion would be checked to confirm which CIM schema revision the logging data conforms to before parsing event records. A chassis-SecurityBreach flag flipping to true during off-hours would be a strong signal of physical tampering.

What Can Be Monitored

  • product identity (name/vendor/version)
  • chassis manufacturer/model/serial number
  • chassis physical security breach status
  • chassis lock presence
  • SML/CIM schema version
