       emsagent	 - SNMP subAgent that services Event Monitoring Services Noti‐


       emsagent is a subAgent that is attached to the SNMP Master Agent	 (snm‐
       pdm).   The emsagent provides the trap notification for the Event Moni‐
       toring Services.	 The emsagent is a separate process.  The SNMP	Master
       Agent binds loosely to the emsagent.

       The  emsagent  sends  information  to  a	 management station without an
       explicit request from it.  Such an operation is called  a  "trap."   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 emsagent collaborate to send EMS event
       traps.  For example, a trap is  sent  when  the	disk  being  monitored
       fails.	A  complete  list of all the EMS-related traps can be found on
       systems with OpenView and ClusterView installed.	 On an	OpenView  man‐
       agement	  station,   the   trap	  descriptions	 can   be   found   in
       /usr/OV/conf/$LANG/cvtrapd.conf	 (or	/usr/OV/conf/$LANG/trapd.conf)
       (9.X),	    or	    /etc/opt/OV/share/conf/$LANG/cvtrapd.conf	   (or
       /etc/opt/OV/share/conf/$LANG/trapd.conf) (10.X).

emsagent Startup
       Startup is controlled by the setting of the  AUTOSTART_EMSAGT  variable
       in the /etc/rc.config.d/emsagtconf file.	 If AUTOSTART_EMSAGT is set to
       1, the emsagent is started automatically each time the system boots.

       If configured for autostart, the emsagent should startup automatically,
       after  the  SNMP	 Master Agent starts, each time the system reboots, or
       anytime 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/emsagent  will  start  the	emsagent 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 emsagent.
       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 controlled by
       adjusting values in the configuration  script  /etc/rc.config.d/emsagt‐

       There are two ways to start the SNMP Master Agent and the emsagent man‐
       ually.  The first way is to execute snmpdm and then start  emsagent  by
       invoking the emsagent executable (/etc/opt/resmon/lbin/emsagent).

       The second and simplest way to start the SNMP Agent manually is to exe‐
       cute 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.


       emsagent was developed by Hewlett-Packard.

   Environment Variables
       LANG determines the language in which messages appear. If LANG  is  not
       specified  or is set to the empty string, a default of "C" (see lang(5)
       is used instead of LANG. If any internationalization variable  contains
       an  invalid  setting,  emsagent	behaves as if all internationalization
       variables are set to "C." See environ(5).

   International Code Set Support
       Supports 8-bit and 16-bit character code sets.
