How to Configure Demo Visualization

1. Run nmetrics-oml2 by installing

   apt-get install oml2 oml2-apps 
   

(I believe these are available for yum as well, but not sure.)

2. Then they need to run:

   nmetrics-oml2 -s 10 -m -i eth1 -c --oml-collect tcp:155.99.144.115:3003 --oml-id $SENDER --oml-domain gec22
   

Where the flags mean:

-c = CPU measurements, -i <interface> = network measurements, -s N = run every N seconds, -m = memory measurements

And where $SENDER is a unique name (unique over all experiments and within this experiment). I suggest something like slice-name_node_name but anything will do.

3. Check if it's working. The correct output looks like this:

   nmetrics-oml2 -s 10 -m -i eth1 -c --oml-collect tcp:155.99.144.115:3003 --oml-id msb-node0 --oml-domain gec22
