Description: Manages Synology NAS iSCSI LUN configuration, capacity, and connection status.

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-ISCSILUN-MIB?

SYNOLOGY-ISCSILUN-MIB is a Synology Inc. (enterprise OID 6574) proprietary MIB reporting per-LUN iSCSI performance characteristics on a Synology NAS. Its LUN table, keyed by index, records UUID, name, read/write throughput (high/low 32-bit halves), read/write IOPS, read/write disk latency, TX/RX network latency, read/write I/O size, queue depth, and LUN type. As a performance MIB it lets an administrator watch per-LUN iSCSI throughput, latency, and queue depth on a Synology NAS. It is deployed on Synology NAS appliances (iSCSI LUN performance). Engineers can download the SYNOLOGY-ISCSILUN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SYNOLOGY-ISCSILUN-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 (iSCSI LUN performance)

Monitoring Examples

An administrator checks iSCSILUNDiskLatencyRead and iSCSILUNQueueDepth to diagnose a slow iSCSI LUN on a Synology NAS.
