-# This script is used to capture I/O on a Linux based system in order to replay

+# This script captures I/O syscalls for replay via the ioriot utility.
#
-# The tool will generate one line per captured I/O syscall to a .capture log
-# file.
-#
-# The key/value separator is ';:,', example line:
-#
-# t=1509989598023;:,i=17159:17358;:,o=open;:,d=167;:,p=/tmp/test;:,f=0;:,m=438;:,

-# It may be that SystemTap will skip probes or interrupts probes in case of
-# system overload. As a result we can have corrupt lines in the log. That's why
-# we use a special field separator ';:,' to detect corrupt lines more robustly.
-#
-# The line uses the following format keys (we use many different of these, the
-# only benefit over a more generic approach is to detect corrupt lines more
-# easily):
-#
-# Format keys:
-# t: Time
-# D: Duration
-# i: PID:TID (process and thread ID)
-# o: Operation name
-# O: Offset or owner/user UID
-# W: Whence
-# d: File/dir descriptor
-# p: File path
-# P: File path 2
-# f: Flags
-# m: Mode
-# b: Bytes
-# c: Count
-# s: Return status
-# t: Optional text
-# F: FCNTL command
-# G: FCNTL arg or user group UID
-# T: Optional text (debugging purpose only)
-# a: Address
