perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi Paul,

First off, thanks for digging down and providing all the debugging output. Looks like the issue is that in the Ivy+ JSON file that the field “no_agent”is set to 1 for ps-40g-hpr01.stanford.edu. That field indicates that this host does not initiate any tests and is generally intended for hosts included in a test mesh that don’t actually read the JSON file. Look like someone just needs to set “no_agent”to 0 (or just remove the definition) for the stanford host in the central Ivy+ mesh config file and regenerate the JSON. Your host should then update regulartesting.conf accordingly. Hope that helps.

Thanks,

Andy

Hello,

We are trying to participate in a second dashboard <http://perfsonar-ma.princeton.edu/maddash-webui/index.cgi?dashboard=IvyPlus>. We already participate in one successfully <https://ps-dashboard.cenic.net/maddash-webui/index.cgi?dashboard=CENIC%2040G-connected>. However, when adding in a second mesh configuration, things do not work as expected.

When I comment in or out the CENIC json from the meshconfig-agent file it is automatically removed from or added to regulartesting.conf correctly. So the update looks to work correctly but it is only working correctly for CENIC’s json file.

It just doesn’t seem to be working with the Ivy+ one. Whenever it reads in this json file it states that the regulartesting.conf is unchanged in the debug despite reading in the json:

Removing both at same time (no mesh configuration):

Adding in only Ivy+ (note it says on write_file that regulartesting.conf is unchanged when doing the compare_file):

Adding back in CENIC (sees that regulartesting.conf has indeed changed and it does add in the CENIC mesh hosts but not the Ivy+):

I can’t figure out where to turn on debug to see if the json read for Ivy+ is failing at a certain point. It definitely only updates for the CENIC json.

https://ps-dashboard.cenic.net/CENIC-Dashboard.json - Works

https://perfsonar-ma.princeton.edu/mesh-ivyplus.json - Doesn’t work.

As other hosts are participating in the Ivy+ dashboard I believe the json file is correct.

Any suggestions?

Thanks,

Paul
