perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi Kathy,

You are correct that it should be able to read the old files. I can successfully translate them so I don't think there are any problems there. It is behaving as if it does not believe there are any tests in those files for it to run. What does /etc/perfsonar/psconfig/pscheduler-agent.json look like? Specifically is there an "address" field set? If there is, remove it and see if that improves things. If it is not there, what is the address of the host that is displaying this behavior?

Thanks,
Andy

I have a perfSONAR Toolkit v4.1.2-1.el7 server that is not initiating tests.
The homepage says "No data available in table" and displays no test results.
The pS does participate in testing initiated by other perfSONARs.

It was built via a clean "Full Install", with ps-migrate backup/restore to
retain historical test results.

The pS is pointing to a meshconfig file that is used by, and working with,
other hosts:

[benninge@perfsonar-xsede ~]$  psconfig remote list
=== pScheduler Agent ===
[
    {
       "url" : "https://psarch.psc.xsede.org/xsede_mesh.json"
    }
]

but doesn't seem to know what to do with the file:

[benninge@perfsonar-xsede ~]$ psconfig pscheduler-tasks
{
    "tasks" : []
}

/var/log/perfsonar/psconfig-pscheduler-agent.log is full of the following:
