vfs_time_audit — samba vfs module to log slow VFS operations
vfs objects = time_audit
This VFS module is part of the samba(7) suite.
time_audit VFS module logs system calls
that take longer than the number of milliseconds defined by the variable
time_audit:timeout. It will log the calls and
the time spent in it.
It's kind of comparable with
strace -T and
is helpful to reveal performance problems with the underlying file
and storage subsystems.
This module is stackable.
VFS calls that take longer than the defined number of milliseconds that should be logged. The default is 10000 (10s).
This would log VFS calls that take longer than 3 seconds:
