NAME

6       vfs_time_audit - samba vfs module to log slow VFS operations
7

SYNOPSIS

9       vfs objects = time_audit
10

DESCRIPTION

12       This VFS module is part of the samba(7) suite.
13
14       The time_audit VFS module logs system calls that take longer than the
15       number of milliseconds defined by the variable time_audit:timeout. It
16       will log the calls and the time spent in it.
17
18       It's kind of comparable with strace -T and is helpful to reveal
19       performance problems with the underlying file and storage subsystems.
20
21       This module is stackable.
22

OPTIONS

24       time_audit:timeout = number of milliseconds
25           VFS calls that take longer than the defined number of milliseconds
26           that should be logged. The default is 10000 (10s).
27

EXAMPLES

29       This would log VFS calls that take longer than 3 seconds:
30
31                   [sample_share]
32                path = /test/sample_share
33                vfs objects = time_audit
34                time_audit:timeout = 3000

AUTHOR

40       The original Samba software and related utilities were created by
41       Andrew Tridgell. Samba is now developed by the Samba Team as an Open
42       Source project similar to the way the Linux kernel is developed.
43
44       The time_audit VFS module was created with contributions from Abhidnya
45       Chirmule.
