SVRCLU-MIB

Description: Manages server cluster configuration, node membership, and cluster resource failover state.

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.

SVRCLU-MIB is a general server-cluster management MIB used to represent the software state of a clustering solution running across a set of server nodes, rather than any single vendor's networking hardware. It exposes cluster identity and versioning information (MIB revision, cluster software vendor and version), the cluster's type, the identity of 'this member' node, the cluster name, and a table of cluster network addresses used for inter-node communication. Its monitoring emphasis is squarely on cluster software status: svrCluSoftwareStatus reports whether the clustering software itself is running/healthy, svrCluSoftwareVersion tracks which cluster software build is deployed, and svrCluThisMember plus the cluster address table let an operator confirm node membership and connectivity are correct - all central to detecting a node that has dropped out of the cluster or is running mismatched software. It is inherently tied to whatever underlying clustering technology it represents (e.g., a Microsoft Cluster Service-like HA framework), with svrCluExtensionOID allowing vendor-specific extensions layered on top of this base model. It is deployed in high-availability server environments where multiple nodes are clustered for failover, and administrators need to verify cluster software health and membership consistency across nodes. Engineers implementing or auditing this functionality typically reference the SVRCLU-MIB RFC/standard documentation for the authoritative specification.

An administrator polls svrCluSoftwareStatus to confirm the clustering service is running normally on a given node, and checks svrCluSoftwareVersion and svrCluSoftwareVendor to verify all cluster members are running matched software builds, since a version mismatch is a common cause of failover problems. svrCluThisMember identifies which node is currently answering the query, while svrCluClusterAddressTable / svrCluClusterAddressEntry (indexed by svrCluClusterAddressIndex) lists the cluster's network addresses, letting the admin confirm inter-node heartbeat communication paths are correctly configured.

Server cluster management MIB for monitoring cluster membership, node status, and cluster-level operational metrics across interconnected servers.
