Hi Pete I can't attend (you know the reason - Fermi run2 review). > server side monitoring - found bug in receiver & decoder code (50% of each trace packet ignored), easy to fix. - loaded data from recent 1-server test to mysql, if I adjust the numbers to account for the bug, average 88MB/file read, largest chunk read 3.2MB, have many more statistics. - recent test proved that the server-side code is non-intrusive. We could try to turn monitoring on all kan servers (once I fix the bug in receiver). How about next week? I have a dedicated machine for collecting data (objydev11) and enough nfs space to accommodate collector's log files. - per recent email exchange: hn for access patterns related discussion: KanSOS - thought more about issue discussed last week: parsing servers' log files. I second Andy's opinion about duplicating efforts, could _easily_ do that via code I already have > administrative interface - I've started looking at xrdclient code to familiarize with xrd code. Goal to implement 2 simple admin commands (e.g. mv, rm) in the next 2-3 weeks. At the same time, discuss list of admin commands that need to be implemented and prioritize (did not have time to study discussion about data mgmt cases sent around earlier) Jacek Peter Elmer wrote: > Hi All, > > The next meeting on xrootd development, testing, deployment and monitoring >will be Tuesday, 14 September, 2004 at 10:15 CA, 19:15 Europe and 18:15 UK.
