perfSONAR User Q&A and Other Discussion

[Zafar Gilani <>]

Hi Jason,

Thanks for the reply. I'm not able to access the machines from my home, I'll try tomorrow morning and let you know. Possibility of a firewall also comes to my mind. I also checked system clock and it seemed to be correct. Addresses:

BW: 115.186.131.105
LA: 115.186.131.107

These machines are deployed at NUST, Islamabad, Pakistan.

Hi,

I've deployed new BW and LA PS nodes but can't seem to view any graphs.
Whenever I go to Service Graphs -> Throughput or Service Graphs ->
One-Way Latency, I get the following:

Problem Handling Request
MA */http://localhost:8085/perfSONAR_PS/services/pSB/* did not return
the expected response, be sure it is configured and populated with data.

For OWAMP I try to view graph and receive following:


   Internal Error - Service returned data, but it is not plotable for
   this measurement pair.

Anyone having any ideas? I've already checked the scheduled tests.
Everything seems to be correct. I also checked
http://psps.perfsonar.net/toolkit/FAQs.html#Q19 but I don't think this
is the case as it has been more than 24 hours since the nodes were deployed.

What is the address of this performance node, is it world accessible or does it have a local address?

I would suggest looking in the database by hand to see if there is recent data:

  mysql -u root

Once at the mysql prompt try these commands:

  use owamp;
  show tables;

Look for a table that has data for 20101125_* or similar.  Try the same for bwctl:

  use bwctl;
  show tables;
  exit;

There should be data for 201011_*.  If you don't see recent data tables, you are not getting data from the regular tests (even though you did set them up).  This could be because your system clock is not correct/not running, firewalls are preventing the BWCTL/OWAMP tests, or perhaps some other reason.

Let us know what you see and we can debug further, thanks;
