Details:
(For reference - http://xrootd.org/doc/dev/xrd_monitoring.htm)
Right now we have the following info in the summary monitoring:
xrootd.ops.rd (int64, number of read requests)
Looking at the code, we would like to break this up into three numbers:
xrootd.ops.rdv (int64, number of readv requests)
xrootd.ops.rd (int64, number of read requests *excluding readv*)
xrootd.ops.rdu (int64, number of read requests, including those from
unpacking readv)
The idea here is that we want to monitor CMS applications relative usage of
read versus readv, and we want to see the overall impact CMS has on the
underlying filesystem (crudely estimated by link.out / xrootd.ops.rdu), or
just looking at the xrootd.ops.rdu rate.
Thanks!
