Configure MRTG to get IPv4 usage statistics

Hello Experts.

I installed MTRG, but I need to configure it to collect statistics to be sent to RIPE, as shown in this example:

http://www.ripe.net/lir-services/resource-management/ipv4/ipv4-verification-sample-mrtg-graphs

The statistics should show the following:

•the IP capacity for each area/pool of IPs
•the IP usage for each area/pool of IPs (min/avg/max on a daily/weekly/monthly basis)

I have some subnet of IP addresses and to build the statistics, it is assumed that an IP address is used when responding to ping (echo-replay).

I think we can use nmap, changing the script in this example:

you can help me to edit the script?

Thanks

Hi.

> I have some subnet of IP addresses and to build the statistics, it is assumed that an IP address is used when responding to ping (echo-replay).

Is it assumed by you or by RIPE?
I would suggest another definition is "IP if it reponds to TCP/UDP requests on any port, or it responds to ping or it initiates connections on any TCP/UDP port".

Most firewalled Windows just never respond to ping.

Modified script, that shows exact IP count (not %) is below. It is also faster.

Regards,
Arty

nets="1.1.1.1-254 2.2.2.2/24"

nrup=`nmap -n --min-parallelism 150 --max-retries 1 --host-timeout 1501 -sP $nets 2>&- | grep "hosts up" | cut -d\( -f2 | cut -d" " -f1`

echo $nrup
echo 0

Hi,

the script works!! I' put the script in ping_scan.sh, ad get this with mrtg.cfg

Target[xyz]:  `/opt/mrtg/ping_scan.sh`
MaxBytes[xyz]: 2000
Unscaled[xyz]: dwmy
Options[xyz]: growright,gauge,noinfo,nopercent
ShortLegend[xyz]: IP USAGE
Title[xyz]: % IP usage
PageTop[xyz]: <h1>RIPE PUBLIC IP USAGE STATISTICS</h1>

In attachment a screenshoot of the statistics (daily).
Is possible to change "byte per seconds"  with "IP address" link this like:
