Description: Defines Sun Cluster event notifications for resource group state changes and cluster fault events.

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 SUN-CLUSTER-EVENTS-MIB?

SUN-CLUSTER-EVENTS-MIB is a vendor-specific MIB from Sun Microsystems (now Oracle) that monitors the Solaris Cluster (Sun Cluster) event framework, exposing a table of cluster-generated events such as resource-group state changes and fault conditions. It provides an events table recording each event's cluster ID/name, originating node, event class and subclass, severity, and initiator, giving visibility into the high-availability clustering software's operational history. Monitoring this MIB is central to tracking cluster software health, since event severity and subclass reveal whether a node has failed, a resource group has failed over, or another fault has occurred, complementing hardware-level monitoring with cluster-software-level fault detection. It depends on the underlying Solaris Cluster event framework and typically coexists with Sun/Oracle hardware-monitoring MIBs covering the physical servers in the cluster. It is deployed on Sun/Oracle SPARC or x86 servers running Solaris Cluster software in high-availability clustered configurations, and administrators can download the SUN-CLUSTER-EVENTS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SUN-CLUSTER-EVENTS-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

Sun/Oracle server running Solaris Cluster (Sun Cluster) software
SPARC or x86 cluster node

Monitoring Examples

Polling escEventTableCount gives a quick indicator of how many events have accumulated, while walking escEventsTable/escEventsEntry (keyed by eventIndex) exposes eventClusterName, eventNodeName, eventClassName/eventSubclassName, and eventSeverity for each recorded event. An admin would watch for high-severity entries with eventInitiator indicating an unexpected node or resource-group failover, which would signal a cluster fault requiring investigation.

What Can Be Monitored

event severity
event class/subclass
originating cluster node
resource group/cluster fault events

SCE escEventTableCount	1.3.6.1.4.1.42.2.80.2.1.1	ScEventTableCount	read-write	Maximum number of event instances maintained in this MIB. When escEventsTable has this many entries and a new entry is added, the earliest entry will be retired
escEventsTable	1.3.6.1.4.1.42.2.80.2.1.2		not-accessible	The table contains one entry per CMM Events
escEventsEntry	1.3.6.1.4.1.42.2.80.2.1.2.1		not-accessible	The entry describes an event
SCE eventIndex	1.3.6.1.4.1.42.2.80.2.1.2.1.1	ScEventIndex	read-only	An index to refer to a cluster event. The index numbers increase monotonically as events are added to the MIB, and the oldest events are deleted from the MIB. If the MIB is restarted, the index number restarts from 1.

SCE eventPublisher	1.3.6.1.4.1.42.2.80.2.1.2.1.10	ScEventPublisher	read-only	the event publisher
C64 eventSeqNo	1.3.6.1.4.1.42.2.80.2.1.2.1.11	Counter64	read-only	the subclass-unique sequence number for this event
SCE eventPid	1.3.6.1.4.1.42.2.80.2.1.2.1.12	ScEventPid	read-only	the process ID of the event issuer
