Title : Install MRTG OS : BSD Distro : FreeBSD URL : http://www.freebsd.org
Install SNMP using Ports
# cd /usr/ports/net-mgmt/net-snmp
# make && make install && make clean
Add Two Lines into /etc/rc.conf
snmpd_enable="YES"
snmpd_flags="-a -Lsd -p /var/run/snmpd.pid"
# chmod 444 /usr/local/etc/rc.d/snmptrapd.sh
Configure snmpd.conf
# snmpconf -i
a. Edit snmpd.conf
b. Choose : System Information Setup
c. You will get
1: The [typically physical] location of the system.
2: The contact information for the administrator
3: The proper value for the sysServices object.
d. Fill up 1 and 2. Please pay attention to option 3
e. When finish, back to main menu and choose 2.
f. Choose 3, a SNMPv1/SNMPv2c read-only access community name
h. Put in community name such as, foo
i. In hostname and network mask we enter 127.0.0.1
j. Setup OID , leave blank
k. Back to menu
l. The IP address and port number that the agent will listen on.
Finish generate configuration file.
# /usr/local/etc/rc.d/snmpd.sh start
Install MRTG using ports
# cd /usr/ports/net-mgmt/mrtg
# make && make install && make clean
Configure file for MRTG
# cfgmaker foo@127.0.0.1 > /usr/local/etc/mrtg/mrtg.cfg
Edit /usr/local/etc/mrtg/mrtg.cfg , put in Apache Directory
Adding Cron Jon
# crontab -e
Insert
*/5 * * * * /usr/local/bin/mrtg /usr/local/etc/mrtg/mrtg.cfg
Launch Brower and view the file.

Slight Ambiguity
Between steps :
there is some back-tracking involved in finding this menu. Perhaps you could modify this post to include the step and recommended settings (though if you're setting up mrtg I would hope most people have an idea of good policies of settings for this!)
> Edit /usr/local/etc/mrtg/mrtg.cfg , put in Apache Directory
Somewhat ambiguious, I assume this means "Edit the 'WorkDir' definition in your MRTG config." Heads up first timers :).
Oh , crontab is added to the root user .. but I wonder if it can be added to a non-priveleged user instead ... thoughts anyone ? (does simple bandwidth monitoring need root access??)
Other than that, looks excellent !
Thanks for writing this , it helped greatly!
It can, if you use ping with
It can, if you use ping with certain settings you have to be root.
For instance, ping -i .5 -c 3 would require superuser and be a faster way to scan a class C.
This does not help at ALL!!!
To tell you frankly this one doesn't not help me at all. I got stucked with:
# cfgmaker foo@127.0.0.1 > /usr/local/etc/mrtg/mrtg.cfg
After doing this command, I went in to edit the mrtg.cfg (as stated:
# Created by
# /usr/local/bin/cfgmaker foo@192.168.17.186
### Global Config Options
# for UNIX
# WorkDir: /home/http/mrtg
# I Did this part as the working directory because mrtg.cf is in this directory.
WorkDir: /usr/local/etc/mrtg
# I Did this even in the Apache configuration (httpd.conf) still no help at all.
# or for NT
# WorkDir: c:\mrtgdata
### Global Defaults
# to get bits instead of bytes and graphs growing to the right
# Options[_]: growright, bits
EnableIPv6: no

What is the next step in here. Could someone help me.
Need help on this one. Also could someone fix the instruction here.
cfgmaker - lack of target
Based on your posted excerpt of the mrtg.cfg, you're not actually hitting an OID, to be able to pull data.
Here is a sample excerpt from my running config. MRTG is running from a Gentoo box, and it's target is a Gentoo box as well, but the sample should apply to you as well.
The most important thing here is to recognize where you want to pull the data from.
Sample:

Notice my 'Target' line. This is where, within SNMPd, it pulls data from.
generate index page
and how can it generate an index page so that apache would display it in a browser.
