1) configure snmpd.conf

[ ~]$ sudo snmpconf -ig basic_setup 
************************************************ 
*** Beginning basic system information setup ***
************************************************ 
Do you want to configure the information returned in the system MIB group (contact info, etc)? (default = y): y
Configuring: syslocation
Description:
 The [typically physical] location of the system.
   Note that setting this value here means that when trying to
   perform an snmp SET operation to the sysLocation.0 variable will make
   the agent return the "notWritable" error code.  IE, including
   this token in the snmpd.conf file will disable write access to
   the variable.
   arguments:  location_string
The location of the system: Hawthorn Woods IL
Finished Output: syslocation  "Hawthorn Woods IL"
Configuring: syscontact
Description:
 The contact information for the administrator
   Note that setting this value here means that when trying to
   perform an snmp SET operation to the sysContact.0 variable will make
   the agent return the "notWritable" error code.  IE, including
   this token in the snmpd.conf file will disable write access to
   the variable.
   arguments:  contact_string
The contact information: Administrator <admin@sjakio.com>
Finished Output: syscontact  "Administrator <admin@sjakio.com>"
Do you want to properly set the value of the sysServices.0 OID (if you don't know, just say no)? (default = y): n

Description:
 a SNMPv1/SNMPv2c read-only access community name
   arguments:  community [default|hostname|network/bits] [oid]
The community name to add read-only access for: <COMMUNITYNAME>
The hostname or network address to accept this community name from [RETURN for all]: 10.0.0.0/24

Do you want to configure the agent's ability to monitor various aspects of your system? (default = y): Y
Do you want to configure the agents ability to monitor processes? (default = y): y
Configuring: proc
Description:
 Check for processes that should be running.
     proc NAME [MAX=0] [MIN=0]
   
     NAME:  the name of the process to check for.  It must match
            exactly (ie, http will not find httpd processes).

     MIN:   the minimum number to be running.  Defaults to 0.
   
   The results are reported in the prTable section of the UCD-SNMP-MIB tree
   Special Case:  When the min and max numbers are both 0, it assumes
   you want a max of infinity and a min of 1.
