perfSONAR User Q&A and Other Discussion

[Lixin Liu <>]

Hi,

After upgrading to 3.4, I have trouble loading MeshConfig:

# sudo -u perfsonar /opt/perfsonar_ps/mesh_config/bin/generate_configuration
Can't locate perfSONAR_PS/NPToolkit/Services/YumCron.pm in @INC (@INC 
contains: /opt/perfsonar_ps/mesh_config/bin/../lib /usr/local/lib64/perl5 
/usr/local/share/perl5 /usr/lib64/perl5/vendor_perl 
/usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at 
/opt/perfsonar_ps/mesh_config/bin/../lib/perfSONAR_PS/NPToolkit/Services/ServicesMap.pm
 
line 24.

/opt/perfsonar_ps/mesh_config/bin/../lib/perfSONAR_PS/NPToolkit/Services/ServicesMap.pm
 
line 24.

/opt/perfsonar_ps/mesh_config/bin/generate_configuration line 15.

It appears generate_configuration uses *.pm files from
  /opt/perfsonar_ps/mesh_config/lib/perfSONAR_PS/NPToolkit/Services
which does not have YumCron.pm. If I copy
  /opt/perfsonar_ps/toolkit/lib/perfSONAR_PS/NPToolkit/Services/YumCron.pm
to this directory, I can load MeshConfig successfully.

I also have a question about Maddash. If I use
      maUrl:
          default: "http://%row/esmond/perfsonar/archive";
I can get the status for the grid, but what should I use for graphURL?
The original
        http://ndt-sfu.westgrid.ca/serviceTest/delayGraph.cgi...
displays
        Unable to find matching MA key for provided parameters

Thanks!
