perfSONAR User Q&A and Other Discussion

[Jason Zurawski <>]

Hi Soichi;

Correct, if you changed the defaults the web page is unlikely to work.  There 
are two options:

 - Edit the web page to point to the new locations, on a regular pS 
Performance Toolkit it is located here (this may be different for your custom 
setup): /opt/perfsonar_ps/toolkit/web/root/gui/services/index.cgi

 - Symlink the /var locations to the /usr/local locations that you are using. 
 

Thanks;

-jason
