perfSONAR User Q&A and Other Discussion

[Jason Zurawski <>]

Hi Szymon;

I think we need a deeper level of logging, edit the 
'/opt/perfsonar_ps/PingER/etc/daemon_logger.conf file, change this:

> log4perl.logger.perfSONAR_PS=INFO, A1

to this

> log4perl.logger.perfSONAR_PS=DEBUG, A1


And then restart PingER (sudo /etc/init.d/PingER restart).  Once you do that, 
try to view the graphs that were not working, and send any relevant log 
snippets from around that time when you are you using the web interface to 
query the MA.  

Thanks;

-jason
