perfSONAR User Q&A and Other Discussion

["Fligor, Debbie" <>]

I didn’t stay on top of the upgrade to 5.0 on my CentOS7 perfsonar system and 
so my limits file had a bad test in it. I had some time to dig in in June and 
didn’t get it working, but in the process tried to add and delete tests and 
hosts, which somehow broke the test configuration page.

fast forward to last week when i got back to this with a goal of getting 
things working and using perfsonar more, and successfully fixed my limits 
issue, and now my tests are running again, but it did not fix the test 
configuration page issue. 

no matter how I get to the test configuration page it stays with the loading 
image as long as I leave it. Then when I click on the page it shows no test 
by test or by host. the +host and +Test buttons give me a partial screen and 
never save.

I went through the troubleshooting section of the website and looked at lots 
of logs. nothing helpful in the pscheduler logs, but this goes in the ssl 
error log every time I go to the configure test page:

If I’m reading it correctly, I have one host defined twice (or improperly) 
some how? 

the only place I found the hosts (with a lot of grepping directories) was in 
/etc/perfsonar/psconfig/toolkit-webui.json  which doesn’t appear to define it 
twice.  renaming that file to something else and trying to load the page 
didn’t help (I’m happy to rebuild the tests if needed, there aren’t many). 

This has persisted across reboots and uninstalling and re-installing the 
perfsonar toolkit package

Any pointers to what’s stuck/cached and how to make the configure tests page 
work again without wiping the system and starting from scratch is appreciated!
