Hi folks, It appears there are quite a few missing bytes in the detailed xrootd statistics. When comparing the number of bytes sent in the sum of all read/write request entries with the total number of bytes in the close request entries, things are off by a factor of 100 (or more) for CMS jobs. Perhaps not coincidentally, vector read calls are over 99% of the bytes moved by CMS. Is it possible that they are not getting accounted for? Brian PS - for what it's worth, it would be nice if ReadV's could be monitored separately; this allows me to monitor for badly behaving jobs.
