but 'cfgmaker' doesnt run sucesfuly, here is the output

# cfgmaker -- output=/etc/mrtg/mrtgmy.conf --global "workdir:/var/www/mrtg" --global 'options[_]: growright,bits' maaz.mrtg@localhost
--base: Get Device Info on sharf.mrtg@localhost:

plz ignore the above output of cfgmaker.
following is the accurate/exact output of "cfgmaker"

# cfgmaker -- output=/etc/mrtg/mrtgmy.conf --global "workdir:/var/www/mrtg" --global 'options[_]: growright,bits' maaz.mrtg@localhost
--base: Get Device Info on maaz.mrtg@localhost:

In your firt command, snmpwalk, you are using v1 or v2c, and probably you are getting response from v2c.

When you run cfgmaker, you run with SNMPv1 (SNMPv1_Session).

Try specifying v2 for cfgmaker:

Cfgmaker creates MRTG configuration files based on information pulled from a router or another SNMP manageable device.

[community@]router

Community is the community name of the device you want to create a configuration for. If not specified, it defaults to 'public'; you might want to try this first if you do not know the community name of a device. If you are using the wrong community name you will get no response from the device.

Router is the DNS name or the IP number of an SNMP-managable device. Following the name you can specify 6 further options separated by colons. The full syntax looks like this:

router[:[prt][:[tmout][:[retr][:[backoff][:vers]]]]]

Of special interest may be the last parameter, vers. If you set this to '2' then your device will be queried with SNMP version 2 requests.
