Bug ID: 190493
Summary: dtrace: failed to resolve cwd: Unknown variable name
Product: Base System
Version: 10.0-RELEASE
Hardware: Any
OS: Any
Status: Needs Triage
Severity: Affects Only Me
Priority: ---
Component: misc
Assignee: [email protected]
Reporter: [email protected]
dtrace doesn't work as described on page [1].
[1] http://docs.oracle.com/cd/E18752_01/html/819-5488/gcfpz.html
Moreover official examples on "/usr/share" doesn't work as well:
[root@freebsd10 ~]# /usr/share/dtrace/toolkit/opensnoop -c 2>&1 | tail -1
: in action list: failed to resolve cwd: Unknown variable name
It's required a way to find out absolute paths of syscalls like "open". The
only way I see is to concatenate relative paths with "cwd", but variable "cwd"
doesn't work in FreeBSD.
Environment:
root@freebsd10:~ # uname -a
FreeBSD freebsd10.imperium.mephi.ru 10.0-RELEASE FreeBSD 10.0-RELEASE #0
