perfSONAR User Q&A and Other Discussion

[Frederic LOUI <>]

Hi Loukik,

I just installed RRD-MA with PerfSONAR 2.0 bundle. And the installation 
went fine.
Basically, instead of using the native tomcat installation (from Ubuntu 
repository), I just ask the script to download and install tomcat.

I addition, Step 1) to Step 4) conditions are OK. Even after a 
reboot...  ;-)

However, I got now a new issue when trying to see the link utilisation 
using PerfSONARUI...

Here are the details:
1- I configured MA.conf in PerfSONARUI to point to 
http://193.49.159.135:8080/perfSONAR-RRD-MA-2.0/services/MeasurementArchiveService
2- In perfsonar/conf folder, I configured service.properties file: 
service.ma.conf_file=/home/perfsonar/perfsonar-bundle-2.0-RC1/perfSONAR-RRD-MA-2.0/perfsonar/conf/rrd-database_RENATER.xml
3- But from PerfSONARUI, I just select my freshly deployed endpoint and 
when I click on the "Retrieve all" button, nothing happens...
   (The only clue I got, is that "DATA retrieved" but nothing is 
exported from the RRD-MA)
4- The PerfSONARUI is able to reach the RRD-MA. (I can see an opened socket)
    ex: ===>   tcp6       0      0 perfsonar:8080      
oujda.renater.fr:3196   TIME_WAIT
5- Each time I click on "Retrieve all" button, I can see the following 
message in perfsonar_debug.log

2007-04-06 14:59:03,314 DEBUG - RequestHandler: Calling on parser to

extracted request
2007-04-06 14:59:03,329 DEBUG - RRDTypeMAServiceEngine.takeAction: 
Received a request of type - GET_KEY

6- Note that I dont have this issue with python RRD-MA version.
   The RRD META DATA file is well interpreted and PerfSONARUI is able 
to retrieve link utilization.

Any idea upon that issue ?
Do I miss something ?

From my understanding, the file "service.properties" should be tailored 
after the installation. Does my service.properties file is OK ?
In addition, I can see that we have 2 methods so as to get RRD data: one 
is xmlrpc the other one is http (in service.properties).
Is there a direct relationship between the method used (xmlrpc or http) 
and the current issue  ?

Again, thanks in adavcen for your help.
Bgrds/Frederic
