perfSONAR User Q&A and Other Discussion

[Lixin Liu <>]

Hi,

We deployed Mesh Configuration on Friday to all our (WestGrid) hosts.
Since then, our dashboard (MaDDash) stop displaying the latency test
graphs between these hosts.

We can still display graphs from latency hosts themselves. I see the
difference is that the display from latency hosts has key and keyR
value:

http://lat-sfu.westgrid.ca/serviceTest/delayGraph.cgi?url=http://localhost:
8085/perfSONAR_PS/services/pSB&key=165b2bfeb7ebbfdcdb9115d644977df4&keyR=63
3419c5d8813ae26ac1cd61dcc7d785&dstIP=206.12.26.20&srcIP=206.12.24.111&dst=l
at-usask.westgrid.ca&src=lat-sfu.westgrid.ca&type=TCP&length=14400&bucket_w
idth=0.0001

but from dashboard these values are not used:

http://ps-dashboard.computecanada.ca/serviceTest/delayGraph.cgi?url=http://
lat-sfu.westgrid.ca:8085/perfSONAR_PS/services/pSB&dst=lat-usask.westgrid.c
a&src=lat-sfu.westgrid.ca&length=14400


Dashboard is: http://ps-dashboard.computecanada.ca/
Hosts are affected are: lat-*.westgrid.ca.
Mesh Configuration file is:
    
http://ps-dashboard.computecanada.ca/ps-mesh/ComputeCanada-PS-tests.json

We can still display bandwidth graphs correctly.

Thanks,
