NAME

       cmsnmpd - SNMP subAgent that services the High Availability cluster MIB objects

SYNOPSIS

       cmsnmpd

DESCRIPTION

       cmsnmpd is a subAgent that together with the SNMP Master Agent (snmpdm), form the SNMP Agent for a particular system.  The cmsnmpd provides
       the instrumentation for the High Availability cluster MIB objects.  The cmsnmpd is a separate process, yet registers with the  SNMP  Master
       Agent, and the two share a procedural interface.

   Traps
       The  cmsnmpd  sends asynchronous event notifications called "traps".  By default, SNMP traps are not sent to any destination.  To configure
       the agent to send traps to one or more specific destinations, add the trap destinations to /etc/SnmpAgent.d/snmpd.conf.

       The SNMP Master Agent and the cmsnmpd collaborate to send High Availability cluster-related traps and information.  For example, a trap	is
       sent  when  the	cluster  configuration	changes, or when a Highly Available package has failed. A complete list of all the cluster-related
       traps can be found on systems with OpenView installed.  On  an  OpenView  management  station,  the  trap  descriptions	can  be  found	in
       /etc/opt/OV/share/conf/$LANG/trapd.conf.

   Supported MIB Objects
       The  Management	Information  Base (MIB) is a conceptual database of values on the agent system.  The cmsnmpd implements the hp-cluster and
       hp-sgcluster MIB objects.  Included in these MIBs are descriptions of the cluster configuration, as well as  the  current  status  of  each
       cluster	component.   A complete list of all the High Availability MIB objects can be found on systems with OpenView installed. On an Open-
       View management station, the MIB object descriptors can be found in /etc/opt/OV/share/conf/snmpmib.

cmsnmpd Startup
       Startup is controlled by the setting of the AUTOSTART_CMSNMPD variable in the /etc/rc.config.d/cmsnmpagt file. If AUTOSTART_CMSNMPD is  set
       to  1, the cmsnmpd is started automatically each time the system boots. The variable should be set to 1 if you will be using ClusterView to
       monitor your Highly Available clusters through OpenView. If AUTOSTART_CMSNMPD is set to 0, the cmsnmpd is not  started  automatically  when
       the system boots.

       If configured for autostart, the cmsnmpd should startup automatically, after the SNMP Master Agent starts, each time the system reboots, or
       any time the system transitions from run level 1  to  run  level  2.  When  the	system	enters	run  level  2,	the  system  will  execute
       /sbin/init.d/SnmpMaster	which will start the Master Agent.  Similarly, /sbin/init.d/cmsnmpagt will start the cmsnmpd immediately after the
       Master Agent is started.

       Prior to executing these startup scripts the system will examine all scripts in /etc/rc.config.d  for  environment  variables  which  could
       potentially  influence  the startup of the Master Agent and the cmsnmpd.  See the specific startup script or configuration file for details
       on supported environment variables. The user should never modify scripts in /sbin/init.d.  Instead, the startup	behavior  should  be  con-
       trolled by adjusting values in the configuration script /etc/rc.config.d/cmsnmpd.

       There  are  two ways to start the SNMP Master Agent and the cmsnmpd manually.  The first way is to execute snmpdm and then start cmsnmpd by
       invoking the cmsnmpd executable (/usr/lbin/cmsnmpd).

       The second and simplest way to start the SNMP Agent manually is to execute the snmpd startup script which will invoke the Master Agent  and
       all  subAgents  who have been installed and designed to operate in this paradigm.  The snmpd startup script is layered upon the V.4 startup
       paradigm and so makes use of the component startup scripts in /sbin/init.d and configuration scripts in /etc/rc.config.d.   When  snmpd	is
       invoked it passes all its command line arguments to snmpdm and then executes each script found in /sbin/SnmpAgtStart.d.
