writing that they are correct for version x is not always precise. But we're working on that also :-) Signed-off-by: Bjoern Jacke <bjacke@samba.org> Reviewed-by: Andrew Bartlett <abartlet@samba.org> Reviewed-by: Garming Sam <garming@catalyst.net.nz>

<title>DESCRIPTION</title>
|
|
|
|
<para>This VFS module is part of the
|
|
<citerefentry><refentrytitle>samba</refentrytitle>
|
|
<manvolnum>7</manvolnum></citerefentry> suite.</para>
|
|
|
|
<para>The <command>time_audit</command> VFS module logs system calls
|
|
that take longer than the number of milliseconds defined by the variable
|
|
<command>time_audit:timeout</command>. It will log the calls and
|
|
the time spent in it.
|
|
</para>
|
|
|
|
<para>It's kind of comparable with <command>strace -T</command> and
|
|
is helpful to reveal performance problems with the underlying file
|
|
and storage subsystems.</para>
|
|
|
|
<para>This module is stackable.</para>

|
|
by the Samba Team as an Open Source project similar
|
|
to the way the Linux kernel is developed.</para>
