Cluster SNMP Agent and Cluster Management Information Base

Sun Cluster includes a Simple Network Management Protocol (SNMP) agent, along with a Management Information Base (MIB), for the cluster. The name of the agent file is snmpd (SNMP daemon) and the name of the MIB is sun.mib.

The cluster SNMP agent is a proxy agent that is capable of monitoring several clusters (a maximum of 32) at the same time. You can manage a typical Sun Cluster from the administration workstation or System Service Processor (SSP). By installing the cluster SNMP agent on the administrative workstation or SSP, network traffic is regulated and the CPU power of the nodes is not wasted in transmitting SNMP packets.

The snmpd daemon:

• Is an RFC 1157-compliant SNMP agent.

• Is dedicated to support the Sun Cluster (SC) MIB extensions under the enterprise group of Sun Microsystems, Inc.

• Provides the cluster sun.mib in ASCII format.

• Supports SNMP protocol operations including GET-REQUEST, GETNEXT-REQUEST and TRAP.

• Provides the Super Monitor agent smond for data collection.

The Super Monitor daemon, smond, collects hardware configuration information and critical cluster events by connecting to the in.mond daemon from each of the member nodes of the cluster(s). The smond daemon then reports the same information to the SNMP daemon (snmpd).

You need to configure only one smond daemon to collect cluster information for several clusters.

The SUNWcsnmp package contains the following:

• /opt/SUNWcluster/bin/snmpd and /opt/SUNWcluster/bin/smond binaries

• ASCII /opt/SUNWcluster/etc/sun.mib file

• /opt/SUNWcluster/bin/init.snmpd script (snmpd control)

• /var/opt/SUNWcluster/snmpd.conf file (SNMP configuration)

• /opt/SUNWcluster/etc/snmp.traps file (SNMP traps)

• /opt/SUNWcluster/etc/sun-snmp.schema file (SunNet Manager schema)

• /opt/SUNWcluster/bin/smond_conf script (smond configuration)

• /opt/SUNWcluster/bin/smond_ctl script (smond control)

• Applicable man pages
