Continuation Round 2

In this round, I ran plastic-104 for about three days, to try to exercise a monitoring bug.

The raw logs are at ​http://www.gpolab.bbn.com/plastic-slices/continuation/round-2/.

plastic-104

SteadyPerf UDP, using port=5104, time=518400, rate=3, and this table of client/server pairs:

client	server	server address
ganel.gpolab.bbn.com	wings-openflow-2.wail.wisc.edu	server=10.42.104.95
wings-openflow-3.wail.wisc.edu	orbitplc2.orbit-lab.org	server=10.42.104.112
orbitplc1.orbit-lab.org	pl4.myplc.grnoc.iu.edu	server=10.42.104.72
pl5.myplc.grnoc.iu.edu	sardis.gpolab.bbn.com	server=10.42.104.53

One-time prep commands run on each client and server

sudo yum -y install iperf

Commands run on each server

server=<ipaddr>
nice -n 19 iperf -u -B $server -p 5104 -s -i 1

Commands run on each client

server=<ipaddr>
nice -n 19 iperf -u -c $server -p 5104 -t 518400 -b 3M

Results

Generated with

subnet=104
for host in $(awk 'NR%2==1' ~/plastic-slices/logins/logins-plastic-$subnet.txt | sed -r -e 's/.+@//') ; do echo -e "$host:\n\n{{{" ; grep -A 10 -B 1 "Client connecting" pgenigpolabbbncom_plastic$subnet\@$host.log ; echo -e "}}}\n" ; done

and then edited slightly to remove artifacts (like control characters, my prompt, etc).

Analysis

All data seems to have been sent successfully (up to four nines, anyway).
