Following the instructions in PingER End-to-end Reporting version 2. After installing the PingER2 monitoring code, we installed the ping_data gathering agent, and the traceroute server following the instructions. Lastly we had to change the hostname in Raspbian.
sudo nano /etc/hosts
sudo nano /etc/hostname
sudo /etc/init.d/hostname.sh
We temporarily entered the machines as monitors in the PingER meta data base of hosts and successfully gathered the data using the standard overnight cronjob.
