perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi George,

The issue originally reported in this thread was just that tests not created by the Toolkit GUI were not showing up any longer in the Toolkit GUI, but they were still in place and running. This is a known change in behavior. Is this the issue you are seeing or is it that you have actual tests missing?

Also, there should not be anything in pscheduler.d unless you are using the toolkit GUI. If you want to make sure it is still pointing at your meshes you can run the command "psconfig remote list". Also, this is a good resource to get you started in troubleshooting the issue: http://docs.perfsonar.net/psconfig_pscheduler_agent.html#troubleshooting

Thanks,
Andy

Hi,

I’ve had similar issues as Andreas with a perfsonar testpoint node (not a toolkit) that was automagically upgraded from pS 4.0 to 4.1 on Sunday, Aug 19 .  The effect was that all latency and throughput tasks ceased to/from the impacted server after the migration.  I’ve cleared my plate of other tasks and I now have time to focus on this issue. I’ve included the migration log file and the current state of psconfig.  The directory pscheduler.d is currently empty.  Any ideas?

Thanks,

George

meshconfig-agent-tasks.conf translator encountered the following errors:

Nothing to convert. This is not an error if all tests contain added_by_mesh. Ignore any errors above about malformed JSON string.

psconfig translate did not work, but it's probably not an error. It will only translate if there are tasks from the webui or created manually. Any global archives were still converted if this was the case.

And here are a few further psconfig command examples that you may find useful:

psconfig pscheduler-stats
psconfig pscheduler-tasks | jq .tasks[].test
psconfig pscheduler-tasks | jq .tasks[].test.type

If you want to know more about JSON filtering with JQ, I invite you to watch Mark's webinar on our youtube channel: https://www.youtube.com/watch?v=FrT6R75M3BE

We didn't feel we had time for that refactoring this release and a casualty of that decision is that the tests not setup through UI are not displayed on the configuration page. They ARE still displayed in the result listing on the front page assuming you are storing the results in the local measurement archive.

In the meantime, if you need a detailed listing of all the tasks pSConfig will try to setup, whether they be from those configured through the UI or read rom remote templates, then you can run the command “psconfig pscheduler-tasks”.
