perfSONAR User Q&A and Other Discussion

Hey Roderick/All;

The BWCTL and OWAMP data on a toolkit is kept in a local MySQL database.  The 
perfsonarbouy collector process will stick the data here, and then delete the 
temp files that you found in the /var/lib location.  You can access via the 
MySQL command line (or through APIs):

> [root@localhost
>  ~]# mysql -u root
> 
> mysql> show databases;
> +--------------------+

> +--------------------+
> 8 rows in set (0.00 sec)


The schema itself has some documentation located in 
'/opt/perfsonar_ps/perfsonarbuoy_ma/doc' if you need any information on the 
fields.  The alternative method to access is via the web service interface by 
using a client application to send XML requests, or the API that is available 
to create new clients.  There is a write up here of that method:

Thanks;
