perfSONAR User Q&A and Other Discussion

Hello,

I'm having problems generating some OWAMP graphs. Sometimes it works,
sometimes it doesn't, especially when trying to see the 1 week graphs.
When it doesn't work, I get a 500 Internal Server Error - "The server
encountered an internal error or misconfiguration and was unable to
complete your request."
I've checked the logs and I see a lot of:

Mon Aug 06 10:16:38 2012] [error] [client 87.196.X.X] Use of
uninitialized value in string eq at
/opt/perfsonar_ps/serviceTest/cgi-bin/delayGraph.cgi line 151.,
referer: http://X.X.X.X/serviceTest/index.cgi?eventType=owamp

[Mon Aug 06 11:26:48 2012] [error] [client 87.196.X.X] Can't call
method "getDocumentElement" on an undefined value at
/opt/perfsonar_ps/serviceTest/cgi-bin/delayGraph.cgi line 279.,
referer: http://X.X.X.X/serviceTest/index.cgi?eventType=owamp

I'm guessing some kind of timeout is happening in the .cgi?


Also, is there a way that I can graph older measurements? For example,
a specific day or week in the past month. And is it possible to
retrieve the one-way delay, loss and jitter values for a specific time
window?

Thank you for your time!


Kind Regards,
