perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

Looks like there might be a bug in the delay graphs. The different URL forms 
is intentional, when just the source and dest are provided the graph looks-up 
the metadata keys. I found a bug in the graph and the attached patch seems to 
fix it. If you download the attached file and run the following, things 
should start working right away:

cd /opt/perfsonar_ps/serviceTest/
patch -p0 < /path/to/delayGraph.patch

You'll need to replace /path/to/delayGraph.patch with the location where you 
downloaded the patch attached to this email. Let me know if it gives you any 
issues. I also added the change to our main source repo and it will be rolled 
into the next release.

Thanks,
Andy
