Hi Peter, Since I've already done a few things towards getting xrootd server monitoring data into MonALISA, I'm looking forward towards this. Unfortunately I will be unavailable the whole next week (I have an exam at my university), but I would suggest to have this meeting next Tuesday, for example, if it's possible for you too. Cheers, Catalin. Peter Elmer wrote: > Hi Derek and Catalin, > > On Thu, Oct 06, 2005 at 02:38:36PM +0200, Derek Feichtinger wrote: > >>You are right.
