perfSONAR User Q&A and Other Discussion

[Soichi Hayashi <>]

I see.. I did following.

2013-09-27 19:31:07 UTC [root@perfsonar-bw:/var/lib]# ls -la perfsonar

lrwxrwxrwx 1 root root 20 Sep 27 19:31 perfsonar -> /usr/local/perfsonar

(on both perfsonar-bw and perfsonar-lt)

Reverted config change, rebooted them, and now I seeing "Running" next to perfsonar BUOY regular testing.

I still have 2 issues, however,

1) When I go to throughput service page > https://perfsonar-bw.grid.iu.edu/serviceTest/index.cgi?eventType=bwctl

I see no entry under "Active Tests" for perfsonar-bw. Do you know how to enable all inactive tests?

2) For both -bw and -lt instances, I still see "Traceroute Regular Testing" showing "Not Running". Do I need to worry?

Hi Soichi;

Correct, if you changed the defaults the web page is unlikely to work.  There are two options:

 - Edit the web page to point to the new locations, on a regular pS Performance Toolkit it is located here (this may be different for your custom setup): /opt/perfsonar_ps/toolkit/web/root/gui/services/index.cgi

 - Symlink the /var locations to the /usr/local locations that you are using.

Thanks;
