perfSONAR User Q&A and Other Discussion

["Andrew Lake" <>]

Hi,

In both cases it is trying to get data from the Central MA run by OSG at http://psds.grid.iu.edu/esmond/perfsonar/archive/. That is populated by periodically polling the MAs running locally on each of your machines and copying the results to psds.grid.iu.edu. It might be worth checking that the software pulling the results is able to retrieve them. That is something developed within OSG so I have copied Shawn McKee who can help point you in the right direction. Since your MA is only open to certain locations it would seem, it’s possible its just a firewall issue or similar and the software pulling the results is just getting blocked. That’s just a guess, but may be a good place to start if you have already confirmed you have the data locally.

Hope that helps,

Andy

Hi,

 

My perfonsar hosts appear in maddash with missing data for all lines/columns. All squares are half orange…

The issue can be seen on this dashboard (GRIF perfsonar02 host) : http://psmad.grid.iu.edu/maddash-webui/index.cgi?dashboard=Dual-Stack%20Mesh%20Config

 

The errors displayed is :

“Unable to find any tests with data in the given time range where source is ccperfsonar1.in2p3.fr and destination is perfsonar02.datagrid.cea.fr”

 

Thing is.. I don’t see many things in the error logs.

It is as if tests were running, but data did not appear in the results/measurement archives in the right place. Or at least in maddash.

Because when I look here : http://ccperfsonar1.in2p3.fr/toolkit/ , I see bidirectional results.

When I look here : https://perfsonar02.datagrid.cea.fr/toolkit/, I also see bidirectional results

 

Side question would be : where does maddash look for those test results ? Locally on the perfsonar host ? using http (filtered out except for the perfsonar maddash network, i.e 129.79.53.0/24 and 192.41.231.110) or https ?

 

The only thing that I see repeated many times a day in the logs are peer errors :  “Peer cancelled test before expected”

 

Example :

I am assuming there is some port filtered out somewere or some misconfiguration, but I’d appreciate some help hunting down the issue as my logs do not help much…

 

Thanks && regards
