perfSONAR User Q&A and Other Discussion

[John-Paul Robinson <>]

Hi Andrew,

I had rebooted and did again this morning.  No yum updates are pending at this time.

I just noticed that my "old" throughput tests are in fact accessible and working just find at the link:

https://perfsonar-10g-scidmz.uabgrid.uab.edu/serviceTest/index.cgi?eventType=bwctl

The interface and data are still there but I can't seem to get to it through the front page.

The place where I see the error is from clicking on the Throughput/Latency Graphs link on the left side of the web interface.  It loads a new page (instead of the one above) with a spinning wait icon.  After the icon spins around I get the error:

https://perfsonar-10g-scidmz.uabgrid.uab.edu/serviceTest/psGraph.cgi

So my data is all good, just don't know how to get to it through the new front page.  I read over the updates link but don't see anything there that helps (btw my automatic updates were config'd from the cmd line).

Hi,

Have you tried rebooting the host? The 3.4 update requires a reboot to complete the upgrade. See the notes we have plastered on the "enabled services" web page, in our release email and in the docs (http://docs.perfsonar.net/manage_update.html#automatic-updates) regarding the limitations of auto-updates.

Thanks,

Andy

Hi,

So...automatic yum updates are good for catching critical vulnerabilities.

Apparently, they are are not so good for maintaining the state of my service.

I never explicitly requested an upgrade to 3.4 but seem to have gotten some of the bits anyway:

My throughput and traceroute tests both report "Error retrieving test data: undefined".  The traceroute error adds that it's a 500 internal server error, so maybe some backend is dead.

Looking at the regular testing log it appears there is still some regular testing and logging going on.  I see updates to tables and test that look like they are doing what they are supposed to do,  so maybe this is just a problem with the visualizer component.

This is what I see in my httpd error_log when trying to view the throughput tests:

I looked over the update notes but don't see anything that applies.  The comment about checking on the data upgrade doesn't seem to work:

$ sudo less /var/log/perfsonar_ps/psb_to_esmond.log
/var/log/perfsonar_ps/psb_to_esmond.log: No such file or directory

Hoping to get some clarity.
