1. MaDDash and other Research DMZ tools
Pete Siemsen, NCAR and FRGP
Westnet Meeting, June 25, 2019

2. MaDDash Visual way to display lots of network performance data
Simple green/yellow/red grid of connection health
Easy top-level way to see how a network is doing
Grid layout can suggest relationships between problems
Allows drill-down into problems
Deployed with perfSONAR

4. MaDDash example

5. MaDDASH demo
To demonstrate drill-down, must look at a real MaDDash, not a screenshot

6. Creating a MaDDash grid
Install perfSONARs
Define the central data node
Develop a test plan
Define tests
Define grid properties
Let it run
Fix the problems

7. Problems Configuration is complex
Default “All-to-all” grid is confusing, though often used
Too many cooks spoil the MaDDash
Evolution of MaDDash means obsolete documentation exists

8. Take a class Google for “FIONA Workshop”
See the training slide deck at
2019/blob/master/maddash--ma/PRP-FIONA-Workshop-LaJolla-MaDDash- jhess-final.pdf
