Basic help needed

[deneken01]

Dear all,

I am new to Cacti. My former colleuge was wrking with MRTG, but when he left he did not leave any documantion on how he did set it up. Now I am supposed to get a new system up and running. After installing Cacti on a Debian GNU/Linux 2.2 machine the standard traffic is working fine.
But when I want to get CPU/MEMORY and PING results of Cisco equipment I am running in to some difficulties. I am working now for about 4 weeks on this problem.
Can some one help be by sending "step-by-step" information on how to add a new Data source for this.
On the website of cacti I also looked into the source of some graphs, but did not figured out..

Please help

Thanks in advance..
