Will do. BTW the nodes I have chosen to monitor at the sites are in general the web servers at the site, e.g. www.bu.edu www.harvard.edu www.uchicago.edu www.indiana.edu ns1.uta.edu www.lunet.edu www.ucsd.edu ns1.lbl.gov www.msu.edu If you have more appropriate hosts (e.g. servers that are relevant to LHC-ATLAS) to monitor at each site then let me know so we can monitor them instead. -----Original Message----- From: Young, Charles C.

I thought Oklahoma State was in the Southwest Tier 2. Not true. I was thinking about a different project on ATLAS where we are working with them. Southwest T2 is made up of UNM, UTA, Oklahoma and Langston. Please add Michigan State. They are part of Great Lakes T2 with Michigan. -- Charles C.
