perfSONAR User Q&A and Other Discussion

[Brian Tierney <>]

Jim:

Looking at http://bwctl.ucsc.edu/toolkit/, your lookup service is down.

There is an updated 'service_watcher' script that should makes sure it will 
stay up.

Here are the steps to install it:


1)    Download the file:

wget -c 
http://anonsvn.internet2.edu/svn/perfSONAR-PS/trunk/perfSONAR_PS-Toolkit/scripts/service_watcher

2)    Change the permissions for the file to enable execution:

chmod a+x service_watcher

3)    Copy the file to the proper location:

sudo cp service_watcher /opt/perfsonar_ps/toolkit/scripts

4)    run the script

sudo /opt/perfsonar_ps/toolkit/scripts/service_watcher


Then wait a couple hours, and your services should appear here:
   https://stats1.es.net/perfSONAR/directorySearch.html


I'll answer some of your other questions below in a follow up email.
