perfSONAR User Q&A and Other Discussion

[Jerome Durand <>]

Thanks to all of you guys!

Now the thing works. I had to rollback to my old configuration using 
eventType format. I just had to restart Tomcat :)

Some comments:
  - it's not so difficult to install bu there are so many things it is 
difficult to understand how they interact together. For example the 
"restart tomcat" thing mighgt better be explained.
  - example configuration file, and request and reply should be given. 
It should be possible to test the service this way, before going to 
perfSONARUI
  - the environment variables should maybe be setup automatically by 
the installation scripts?
  - eXist role should be better explained (but I think some of you guys 
are working on it)
  - Documentation should contain the pages that Vedrin sent me, but 
related to this version only. I mean the web page should be packaged in 
the release.

I'll certainly provide more detailed comments. In general it is probably 
not so complex but there are so many small things to do that it is 
really hard to understand which step is okay and which step is not...

Thanks again, I'll probably come back to you later with some other 
questions as usually :)

Jerome
