perfsonar development work

[Domenico Vicinanza <>]

Hello,

I am writing you on behalf of the GEANT2 Service Desk. We are installing 
and configuring a monitoring server based on Nagios (equipped with 
customized plugin to check perfsonar services) and on syslog parsing (we 
are running syslog-ng receving, among the others, perfsonar logs).

We have a remark and a request. The remark regards the fact that there 
is no perfsonar service name in the log messages, when the service is 
dealing with a web-service request. As an example, having a look at the 
LS, AS or RRD-MA logs those messages are all looking the same:
2008-06-04 12:40:36,278  INFO - RequestHandler: Service received a request
2008-06-04 12:40:36,294  INFO - RequestHandler: Service sent a 
successful response

with no specific tag. This would be fixed in future (as far as I 
understood) according to the 
http://wiki.perfsonar.net/jra1-wiki/index.php/Service_Log_List. Could 
you just confirm that it is correct?

The request is related to log content. I tried this morning to simulate 
an error (I used a wrong schema in the request: in the eventType field), 
basically a wrongly formatted request to a service (pS LS), using 
perfsonar UI.
The error message the web service returned was perfectly reflecting the 
problem occurred:

   <nmwg:eventType>error.ls.eventtype_not_supported</nmwg:eventType>

On the other hand the log files reported:

INFO - RequestHandler: Service received a request
INFO - RequestHandler: Service sent a successful response

Which is not true. It is true that, from a functional point of view the 
service was replying correctly to the response, but it is not true that 
the response was successful.
Our proposal is that the log should contain the error reported, 
something like:

ERROR - RequestHandler: Service sent an error response - Error message: 
error.ls.eventtype_not_supported

This would help us a lot in supporting users, debugging problems and 
taking the proper actions when a problem is detected.

Many thanks in advance,
Domenico
