Description: LeftHand Networks MIB for monitoring operational health and status on LeftHand NUS iSCSI SAN storage appliances.

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 LEFTHAND-NETWORKS-NUS-COMMON-STATUS-MIB?

LEFTHAND-NETWORKS-NUS-COMMON-STATUS-MIB is a small, vendor-specific SNMP module from LeftHand Networks providing a simplified overall operational status indicator and accompanying status message for LeftHand NUS iSCSI storage appliances. Unlike its companion INFO MIB, it exposes just two objects: an aggregate status code and a human-readable status message, both intended to give a quick health summary of the storage node. Despite its minimal object set, it directly supports monitoring hardware and software status: the status/statusMessage pair is the appliance's own rolled-up self-assessment, reflecting underlying conditions (temperature, fan, or power supply issues detailed in the companion INFO MIB) as a single alarm-style value. It is designed as a companion to LEFTHAND-NETWORKS-NUS-COMMON-INFO-MIB, which supplies the detailed hardware readings underlying this summary status. It is typically deployed in HP LeftHand/StoreVirtual iSCSI SAN clusters as a lightweight top-level health check polled frequently by monitoring systems. Engineers can download the LEFTHAND-NETWORKS-NUS-COMMON-STATUS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LEFTHAND-NETWORKS-NUS-COMMON-STATUS-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

  • HP LeftHand Networks NUS/NSM iSCSI storage appliance
  • HP StoreVirtual storage node

Monitoring Examples

A monitoring system polls the status object on a schedule to get a quick top-level health code for the storage node, and reads statusMessage for a human-readable description of any abnormal condition (e.g., a power supply failure or overheating). Because this MIB has only two scalar objects, it is used as a fast summary check rather than for detailed diagnostics; if status indicates a problem, the administrator would then cross-reference LEFTHAND-NETWORKS-NUS-COMMON-INFO-MIB for the specific temperature, fan, or power supply reading causing it. A transition of status from normal to alarm is the primary trigger event this MIB exists to report.

How to Use in IPNetwork Monitor

Example using status OID:

Select an HP LeftHand Networks NUS/NSM iSCSI storage appliance (rollup health 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 status into the Find box to locate it in the OID tree, then select it and click OK. It reports leftHand Networks MIB status. 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 INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value is anything other than 'online', since that indicates the condition this object reports has changed to one worth investigating. Click Finish to create the monitor; you can adjust any parameter later.
