The network map makes a map of the room. It queries data from the switches at 128.237.157.253 128.237.157.254 using snmp and builds a JSON output to be read by d3js force layout.
The script lives in monitor:/home/network-map and requires:
- bash 4
- snmpwalk and snmpget
- /usr/sbin/arp
And the server knowing the hostname of all the relevant machines (This is true on due to awesie_'s arp logger)
The script main file is network-mapper.sh and running it with no-args will query all the switches and do it's thing.
The script also uses 2 libraries that I wrote called libarphelper.sh libsnmphelper.sh. These scripts should be located in the same directory as network-mapper.sh
Once the JSON has been generated it will echo it out to stdout and you can save it to your d3js viewer directory.
I have one hosted here http://monitor.club.cc.cmu.edu/networkmap/
