Hi,
I am a new to dtrace and have a little question I am hoping you could clear up.
When I run the following I command I get the ouput of the file which is being
stat by ftsat64, when I quantize this what reference is the Value field using
dtrace -n
syscall::fstat64:entry''{@[fds[arg0].fi_pathname]=quantize(arg0)}''
/opt/VRTSperl/lib/5.8.6/vars.pm

Just looking for some pointers really on what this would relate to.

Hi Allan, Could be a socket or a fifo. Suggest you replace fi_pathname with fi_fs and see what you get in terms of filesystem type. Pathnames name make no sense for some types of files such as sockets and some versions of some filesystems such as vxfs don''t fill in the required fields, so the pathname becomes unknown. Let us know if you have any further questions.
