Traffic Monitoring with MRTG

To monitor your network performance and traffic folw, you need to setup 1 NMS box in your network.MRTG can monitor SNMP network devices and show how much traffic has passed through the interfaces.

MRTG can run on both Unix/linux and Windows.For installion, can download from http://oss.oetiker.ch/mrtg/


Here's simple and quick configuration guide to add your devices into MRTG.
Once you installed MRTG and Apache is running, add your devices with these following steps
- Enable SNMP on device

- Get the SNMP community String

- Allow SNMP connection from MRTG box to poll data

- If the device is under firewall, open the rule for it


If you have all of these, you are ready to add your devices.
- Go to your MRTG installed path..#cd /usr/local/mrtg
- Create cfg file for device.

#./cfgmaker SNMP-community-srting@IP-address-of-device > device.cfg

for example; #./cfgmaker readonly@192.168.1.1 >192.168.1.1.cfg

MRTG will collect the SNMP info and create the cfg file 192.168.1.1.cfg
- Verify your file.#ls -al your config file is 192.168.1.1.cfg
- Modify cfg file using vi Editor

(vi ref gide - http://www.unix-manuals.com/refs/vi-ref/vi-ref.htm)

#vi 192.168.1.1.cfg

Add following lines to Specify the path for your running directory.

htmldir: /usr/local/mrtg/www

Imagedir:/usr/local/mrtg/www

Logdir: /usr/local/mrtg/log
save and quit the file with :wq
- Start MRTG with this command

#/usr/local/mrtg/mrtg /usr/local/mrtg/192.168.1.1.cfg

run this command 3 or 4 times.
- Create index file to view with Apache.

#./indexmaker 192.168.1.1.cfg

Verify under your html path /usr/local/mrtg/www

You should see index.html file and your graphs.
- View your graphs via browserhttp://your-mrtg-IP/www/ (depends on your Apache config)
You will see your MRTG graphs. Like this..http://www.stat.ee.ethz.ch/mrtg/

But your graphs will not move. You need to add cron jobs to poll by MRTG every 5 min.
- Add cron jobs.

#crontab -l (view your currnet crons)#crontab -e (add your cron)5,10,15,20,25,30,35,40,45,50,55,00 * * * * usr/local/mrtg/mrtg /usr/local/mrtg/192.168.1.1.cfg
After 5 or 10 mins, you will see your graphs.
Done!!!!

Cisco and Pearson VUE partner to expand access to Cisco certification

No more Prometric with Cisco...

We're pleased to announce that Pearson VUE will be the single vendor of Cisco® certification exams worldwide, effective August 1, 2007. We’re very excited about this change, and we’re confident that as a valued Cisco customer, you’ll benefit from the new level of security, global access, and innovative technology that will now be available through this collaboration. Cisco and Pearson VUE are partnering to create a new standard for individual information technology certifications and specialization exams, elevating them to the level of prestigious professional certification and licensure programs. As a result of this change, all individual Cisco technical certification exams for Cisco customers and partners will need to be scheduled through Pearson VUE. July 31, 2007, is the last date to take a Cisco exam through Prometric.
As global demand increases for individual Cisco certifications, it is critical that we improve and make our global certification systems more agile. Hence, we need to scale and optimize our test delivery—that is, the administration of Cisco certifications such as Cisco CCNA® and CCIE®. Traditionally, Cisco has used two core test delivery partners worldwide to deliver our individual certification exams: Pearson VUE and Prometric. However, after significant research, Pearson VUE was chosen as Cisco’s single testing partner. Pearson VUE was selected for the following reasons:
• Unparalleled global reach
• Forward-thinking policies and vision of technical resource recruitment
• Ability to scale to new countries with new requirements
• Ability to meet forecasted demands
• Ability to deliver on additional investments to secure Cisco’s test delivery technology
