Demonstrations of funcgraph, the Linux ftrace version.
|

|
|
|
||
|
|
I'll start by showing do_nanosleep(), since it's usually a low frequency
|
||
|
|
function that can be easily triggered (run "vmstat 1"):
|
||
|
|
|
||
|
|
# ./funcgraph do_nanosleep
|

|
|
Tracing "do_nanosleep"... Ctrl-C to end.

The default output shows the function call graph, including all child kernel
|
||
|
|
functions, along with the function duration times. These times are printed on
|
||
|
|
either the return line for the function ("}"), or for leaf functions, on the
|
||
|
|
same line.
|
||
|
|
|
||
|
|
The format of this output is documented in the function graph section of the
|
||
|
|
kernel source file Documentation/trace/ftrace.txt.
|
||
|
|
|
||
|
|
This particular example shows the workings of do_nanosleep, in the first dozen
|
||
|
|
lines, and then schedule() is called to sleep this thread and run another. The
|
||
|
|
inner workings of schedule() is included in the output.
|
||
|
|
|
||
|
|
This output is great for determining the behavior of a certain kernel function,
|
||
|
|
and to identify functions that can be studied in more details using other, lower
|
||
|
|
overhead, tools (eg, funccount(8), functrace(8), kprobe(8)). The overheads
|
||
|
|
of funcgraph are moderate, since all kernel functions are traced in case
|
||
|
|
they are executed, then included in the output if they are.
|
||
|
|
|
||
|
|
Now, if you want to start understanding the general behavior of the kernel,
|
||
|
|
without a certain kernel function in mind, you may be better to begin with
|
||
|
|
CPU stack profiling using perf and generating a flame graph. Such an approach
|
||
|
|
has low overhead, as you are in control of the frequency of event collection
|
||
|
|
(eg, gathering CPU stacks at 99 Hertz). For instructions, see:
|
||
|
|
http://www.brendangregg.com/perf.html#FlameGraphs
|
||
|
|
|
||
|
|
|
||
|
|
For this example, I trace vfs_read() calls by process ID 5363: which is a bash
|
||
|
|
shell. I also include headers (-H) and absolute timestamps (-t). While
|
||
|
|
tracing, in that bash shell, I typed the word "hello":
|
||
|
|
|
||
|
|
# ./funcgraph -Htp 5363 vfs_read
|
||
|
|
Tracing "vfs_read" for PID 5363... Ctrl-C to end.

If you read through the durations carefully, you can see that the shell begins
|
||
|
|
by completing a 19 second read (time between commands), then has a series of
|
||
|
|
100 to 200 ms reads (inter-keystroke latency).
