perfSONAR User Q&A and Other Discussion

Andy,

I can run the tests by hand without a problem.  When I go to the toolkit page of esdis-ps.eosdis.nasa.gov and display the throughput and latency/loss graphs I have current data (see attached).  I verified connectivity to the standalone MA over port 80 & 443.  In a mesh, which hosts are reporting test results to the MA - the source, the destination or both?  What happens if one of them is a no_agent host? 

In my case I have two agent hosts testing with one no_agent host.  On both agent hosts, the throughput/latency/loss graphs shows the source is the no_agent host and the destination is the agent host.  Yet agent host is able to send data to the central MA,it’s displaying on the dashboard, while the other is not.

I’m not sure what log files will indicate the cause of the failure.

Thanks,

George

Hi george,

Looking at the data it appears the OWAMP tests stopped working around January 26th and the BWCTL tests ~January 23rd. You might want to double check the test is still configured. Could also be a firewall change maybe? If you run owping or bwctl by hand do the tests complete?

Thanks,

Andy

I have a situation where I’m unable to retrieve data from OWAMP or BWCTL/iperf tests between two nodes on my dashboard.  The dashboard is run on a standalone centralized MA and I see test results data between these hosts in the esmond perfsonar archive.  One node, esdis-ps.eosdis.nasa.gov is participating in a mesh.  The other node, edclxw41.cr.usgs.gov is a no_agent mesh member.  This same no_agent member is running tests with another member, 207.151.223.222, and those results are being displayed in the dashboard.   I’ve attached a gzipped copy of the esmond archive from the MA and a screen shot of the dashboard.

Thanks,

George
