Description: Manages NEC server cluster node membership, resource groups, and failover policy configuration.
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 NEC-CLUSTER-MANAGEMENT-MIB?
NEC-CLUSTER-MANAGEMENT-MIB is a vendor MIB from NEC for managing server cluster configurations, covering cluster identity, membership of individual cluster servers/nodes, and resource group organization for failover. It exposes objects for cluster name and status, a per-server table with server index, name, status, and priority, and grouping constructs for cluster-wide resource organization. Its core monitoring use is software/service status at the cluster level: tracking clusterStatus and clusterServerStatus lets an administrator detect a node going offline, a failover event, or priority misconfiguration that would affect which node becomes active. There's no explicit dependency on external standard MIBs noted, though it likely coexists with host/OS-level MIBs on the same NEC server platform. It is deployed on NEC server clusters providing high-availability services in enterprise data center environments. Engineers can download the NEC-CLUSTER-MANAGEMENT-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in NEC-CLUSTER-MANAGEMENT-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
- NEC server cluster node
- NEC high-availability server platform
Monitoring Examples
An administrator would poll clusterServerTable/clusterServerEntry by clusterServerIndex to check clusterServerStatus and clusterServerPriority for each node, confirming the expected node holds the highest priority and is marked active/online. A change in clusterStatus at the cluster level combined with a servers table entry flipping to a failed status would indicate a failover has occurred, warranting investigation of the previously active node. clusterServerProductName helps confirm the hardware model backing each cluster member matches expected configuration.
What Can Be Monitored
- cluster overall status
- per-server node status
- server failover priority
- cluster/server naming and comments
- server product/model identity
