Device42 Netflow Collector
Device42’s Netflow Collector is a powerful tool used to get continuous auto-discovery information from your environment.
The collector can be downloaded from http://www.device42.com/autodiscovery and can be run from the command line.
Usage of d42-netflow-collector-windows-v100.exe: -addr string netflow listen address (default "0.0.0.0:2055") -debug show netflow info -h string D42 host name -i int interval in seconds between sends data to D42 (default 300) -ignore-ip string ignore IPs -ignore-port string ignore ports -live-entries display live entries -live-entries-nok display OK live entries -live-entries-ok display NOK live entries -p string D42 password -print-data prints data -u string D42 username
Running Netflow Collector
To run the collector, open the command prompt and navigate to the directory it is stored in. run:
d42-netflow-collector-windows-v100.exe -h https://yourdevice42url -u D42UserName -p D42Password
This will start the listener on port 2055, unless a different port is specified, and will start collecting data sent to this device from your netflow-enabled devices.
On the switch or other netflow enabled device you are using, point the netflow output to the IP address of the server running the Device42 netflow collector.
The collector will collect all data and send to Device42 in 5-minute increments by default, which you can change with the -i switch.
Device42 will receive the netflow data and attempt to associate it with known services in Device42. If there are no services to associate the data with, Device42 will retain the most recent million rows of data, discarding the oldest information as needed, and will match this data as services are discovered.
