Hello Brian
Yes, we also noticed that the detailed monitoring is not working in
v3.2.2. We build a version on top of v3.2.2 adding the two commits:
commit e0ad3459c89a163e600070a15936b8fd5d26ff35
Author: Andrew Hanushevsky <[log in to unmask]>
Date: Wed Aug 22 18:56:19 2012 -0700
Make sure read statistics are updated for sendfile() and mmap I/O.
commit e51db4bb0178a21bbe87ccf7c9349b079c2d7455
Author: Andrew Hanushevsky <[log in to unmask]>
Date: Mon Jul 30 16:52:56 2012 -0700
Correct monitor initialization test to start monitor under all configs.
As far as I can tell the detailed monitoring is now working. Wei might
have done more testing.
Cheers,
Wilko
