Hi,

I was intalling MA Esmond. I was following this guide: http://software.es.net/esmond/rpm_install.html

Is it the right documentation about the MA Esmond installation?

I followed correctly all the guide, but in the end, when I tryed to open the URL http://<ip_host>/esmond/perfsonar/archive/?format=json

I received an error in the browser: "Internal Server Error"

In the log file: /var/log/esmond/django.log is appearing the following errors:

2015-04-15 14:59:34,094 [ERROR] /opt/esmond/lib/python2.7/site-packages/django/core/handlers/base.py: Internal Server Error: /esmond/perfsonar/archive/

Do you have any clue about what is happening?

Thanks,
