This guide suggests using an mrtg config per target, this is rather inefficient as mrtg can do them all in 1 job itself SU Into root before continuing forward. Start by: mkdir /etc/mrtg mkdir /etc/cron.mrtg mkdir -p /var/www/localhost/htdocs/mrtg

/etc/snmp/snmpd.conf 

####
# First, map the community name (COMMUNITY) into a security name
# (local and mynetwork, depending on where the request is coming
# from):

#       sec.name  source          community
com2sec local     127.0.0.0/24        public

####
# Second, map the security names into group names:

#               sec.model  sec.name
group MyROGroup v1                 local
group MyROGroup v2c                local
group MyROGroup usm                local

####
# Third, create a view for us to let the groups have rights to:

#           incl/excl subtree                          mask
view all    included  .1                               80

####
# Finally, grant the 2 groups access to the 1 view with different
# write permissions:

#                context sec.model sec.level match  read   write  notif
access MyROGroup ""      any       noauth    exact  all    none   none

/etc/conf.d/snmpd

  1. Initial (empty) options.

SNMPD_FLAGS="-C -c /etc/snmp/snmpd.conf"


This makes sure SNMPD uses the above /etc/snmp/snmpd.conf, and _only_ that file.

Now the daemon: /etc/init.d/snmpd start /sbin/rc-update add snmpd default SNMPD_FLAGS="-C -c /etc/snmp/snmpd.conf"


НАСтройка

/usr/bin/cfgmaker \ --output=/etc/mrtg/traffic.cfg \ --ifdesc=ip \ --ifref=descr \ --global "WorkDir: /var/www/localhost/htdocs/mrtg" \ --global "Options[_]: bits,growright" \ 

 public@localhost

Далее в ручную поправим файл для того чтобы активировать ppp и lo

в итоге у меня вышел вот такой файл 

### Global Defaults

#  to get bits instead of bytes and graphs growing to the right
# Options[_]: growright, bits

EnableIPv6: no
