Introduction
We wanted to verify whether the sharing cretaed by running on a virtual machine made any statistical difference to the PingER results. Thus we compare the results from PinGER running on a bare metal machine (pinger.slac.stanford.edu) vs running on
...
a VM.
Installation of PingER Measurement Agent (MA pinger2.pl)
...
Spin up the virtual machine.

- To see if the cronjob is running look at the dates on the files /usr/local/share/pinger/pingerCronStat.stdout and /usr/local/share/pinger/pingerCronStat.stderr, they should be withing the last 30 mins (example)
- Examine the above files (in particular the stderr file) to verify pinger2.pl is properly configured (an example of a typical error in the stderr file). If all is well then the stderr file will be empty. Example of a normal stdout file.
