TRACE-CMD-RECORD(1) libtracefs Manual TRACE-CMD-RECORD(1)
trace-cmd-record - record a trace from the Ftrace Linux internal
tracer
trace-cmd record [OPTIONS] [command]
The trace-cmd(1) record command will set up the Ftrace Linux
kernel tracer to record the specified plugins or events that
happen while the command executes. If no command is given, then
it will record until the user hits Ctrl-C.
The record command of trace-cmd will set up the Ftrace tracer to
start tracing the various events or plugins that are given on the
command line. It will then create a number of tracing processes
(one per CPU) that will start recording from the kernel ring
buffer straight into temporary files. When the command is
complete (or Ctrl-C is hit) all the files will be combined into a
trace.dat file that can later be read (see trace-cmd-report(1)).
-p tracer
Specify a tracer. Tracers usually do more than just trace an
event. Common tracers are: function, function_graph,
preemptirqsoff, irqsoff, preemptoff and wakeup. A tracer must
be supported by the running kernel. To see a list of
available tracers, see trace-cmd-list(1).
-e event
Specify an event to trace. Various static trace points have
been added to the Linux kernel. They are grouped by subsystem
where you can enable all events of a given subsystem or
specify specific events to be enabled. The event is of the
format "subsystem:event-name". You can also just specify the
subsystem without the :event-name or the event-name without
the "subsystem:". Using "-e sched_switch" will enable the
"sched_switch" event where as, "-e sched" will enable all
events under the "sched" subsystem.
The 'event' can also contain glob expressions. That is, "*stat*" will
select all events (or subsystems) that have the characters "stat" in their
names.
The keyword 'all' can be used to enable all events.
-a
Every event that is being recorded has its output format file
saved in the output file to be able to display it later. But
if other events are enabled in the trace without trace-cmd’s
knowledge, the formats of those events will not be recorded
and trace-cmd report will not be able to display them. If
this is the case, then specify the -a option and the format
for all events in the system will be saved.
-T
Enable a stacktrace on each event. For example:
<idle>-0 [003] 58549.289091: sched_switch: kworker/0:1:0 [120] R ==> trace-cmd:2603 [120]
<idle>-0 [003] 58549.289092: kernel_stack: <stack trace>
=> schedule (ffffffff814b260e)
=> cpu_idle (ffffffff8100a38c)
=> start_secondary (ffffffff814ab828)
--func-stack
Enable a stack trace on all functions. Note this is only
applicable for the "function" plugin tracer, and will only
take effect if the -l option is used and succeeds in limiting
functions. If the function tracer is not filtered, and the
stack trace is enabled, you can live lock the machine.
-f filter
Specify a filter for the previous event. This must come after
a -e. This will filter what events get recorded based on the
content of the event. Filtering is passed to the kernel
directly so what filtering is allowed may depend on what
version of the kernel you have. Basically, it will let you
use C notation to check if an event should be processed or
not.
==, >=, <=, >, <, &, |, && and ||
The above are usually safe to use to compare fields.
--no-filter
Do not filter out the trace-cmd threads. By default, the
threads are filtered out to not be traced by events. This
option will have the trace-cmd threads also be traced.
-R trigger
Specify a trigger for the previous event. This must come
after a -e. This will add a given trigger to the given event.
To only enable the trigger and not the event itself, then
place the event after the -v option.
See Documentation/trace/events.txt in the Linux kernel source for more
information on triggers.
-v
This will cause all events specified after it on the command
line to not be traced. This is useful for selecting a
subsystem to be traced but to leave out various events. For
Example: "-e sched -v -e "*stat\*"" will enable all events in
the sched subsystem except those that have "stat" in their
names.
Note: the *-v* option was taken from the way grep(1) inverts the following
matches.
-F
This will filter only the executable that is given on the
command line. If no command is given, then it will filter
itself (pretty pointless). Using -F will let you trace only
events that are caused by the given command.
-P pid
Similar to -F but lets you specify a process ID to trace.
-c
Used with either -F (or -P if kernel supports it) to trace
the process' children too.
--user
Execute the specified command as given user.
-C clock
Set the trace clock to "clock".
Use trace-cmd(1) list -C to see what clocks are available.
-o output-file
By default, trace-cmd report will create a trace.dat file.
You can specify a different file to write to with the -o
option.
-l function-name
This will limit the function and function_graph tracers to
only trace the given function name. More than one -l may be
specified on the command line to trace more than one
function. This supports both full regex(3) parsing, or basic
glob parsing. If the filter has only alphanumeric, _, *, ?
and . characters, then it will be parsed as a basic glob. to
force it to be a regex, prefix the filter with ^ or append it
with $ and it will then be parsed as a regex.
-g function-name
This option is for the function_graph plugin. It will graph
the given function. That is, it will only trace the function
and all functions that it calls. You can have more than one
-g on the command line.
-n function-name
This has the opposite effect of -l. The function given with
the -n option will not be traced. This takes precedence, that
is, if you include the same function for both -n and -l, it
will not be traced.
-d
Some tracer plugins enable the function tracer by default.
Like the latency tracers. This option prevents the function
tracer from being enabled at start up.
-D
The option -d will try to use the function-trace option to
disable the function tracer (if available), otherwise it
defaults to the proc file: /proc/sys/kernel/ftrace_enabled,
but will not touch it if the function-trace option is
available. The -D option will disable both the ftrace_enabled
proc file as well as the function-trace option if it exists.
Note, this disable function tracing for all users, which includes users
outside of ftrace tracers (stack_tracer, perf, etc).
-O option
Ftrace has various options that can be enabled or disabled.
This allows you to set them. Appending the text no to an
option disables it. For example: "-O nograph-time" will
disable the "graph-time" Ftrace option.
-s interval
The processes that trace-cmd creates to record from the ring
buffer need to wake up to do the recording. Setting the
interval to zero will cause the processes to wakeup every
time new data is written into the buffer. But since Ftrace is
recording kernel activity, the act of this processes going
back to sleep may cause new events into the ring buffer which
will wake the process back up. This will needlessly add extra
data into the ring buffer.
The 'interval' metric is microseconds. The default is set to 1000 (1 ms).
This is the time each recording process will sleep before waking up to
record any new data that was written to the ring buffer.
-r priority
The priority to run the capture threads at. In a busy system
the trace capturing threads may be staved and events can be
lost. This increases the priority of those threads to the
real time (FIFO) priority. But use this option with care, it
can also change the behaviour of the system being traced.
-b size
This sets the ring buffer size to size kilobytes. Because the
Ftrace ring buffer is per CPU, this size is the size of each
per CPU ring buffer inside the kernel. Using "-b 10000" on a
machine with 4 CPUs will make Ftrace have a total buffer size
of 40 Megs.
--subbuf-size
The Linux kernel tracing ring buffer is broken up into
sub-buffers. These sub-buffers are typically the size of the
architecture "page-size". (4096 or x86). An event can only be
as big as the data portion of a sub-buffer, but in most cases
that’s not an issue. But the time the writer takes to switch
from one sub-buffer to the next has a bit more overhead than
adding events within the sub-buffer. By increasing its size,
it will allow bigger events (although that is seldom an
issue) but also speed up the tracing itself.
The downside of larger sub-buffers is that a "read" of the ring buffer
will pull the sub-buffer size out of the ring buffer and replace it
with a new sub-buffer. This may not have any real impact, but it may
change the behavior slightly. Or it may not!
-B buffer-name
If the kernel supports multiple buffers, this will add a
buffer with the given name. If the buffer name already
exists, that buffer is just reset and will not be deleted at
the end of record execution. If the buffer is created, it
will be removed at the end of execution (unless the -k is
set, or start command was used).
After a buffer name is stated, all events added after that will be
associated with that buffer. If no buffer is specified, or an event
is specified before a buffer name, it will be associated with the
main (toplevel) buffer.
trace-cmd record -e sched -B block -e block -B time -e timer sleep 1
The above is will enable all sched events in the main buffer. It will
then create a 'block' buffer instance and enable all block events within
that buffer. A 'time' buffer instance is created and all timer events
will be enabled for that event.
-m size
The max size in kilobytes that a per cpu buffer should be.
Note, due to rounding to page size, the number may not be
totally correct. Also, this is performed by switching between
two buffers that are half the given size thus the output may
not be of the given size even if much more was written.
Use this to prevent running out of diskspace for long runs.
-M cpumask
Set the cpumask for to trace. It only affects the last buffer
instance given. If supplied before any buffer instance, then
it affects the main buffer. The value supplied must be a hex
number.
trace-cmd record -p function -M c -B events13 -e all -M 5
If the -M is left out, then the mask stays the same. To enable all
CPUs, pass in a value of '-1'.
-k
By default, when trace-cmd is finished tracing, it will reset
the buffers and disable all the tracing that it enabled. This
option keeps trace-cmd from disabling the tracer and reseting
the buffer. This option is useful for debugging trace-cmd.
Note: usually trace-cmd will set the "tracing_on" file back to what it
was before it was called. This option will leave that file set to zero.
-i
By default, if an event is listed that trace-cmd does not
find, it will exit with an error. This option will just
ignore events that are listed on the command line but are not
found on the system.
-N host:port
If another machine is running "trace-cmd listen", this option
is used to have the data sent to that machine with UDP
packets. Instead of writing to an output file, the data is
sent off to a remote box. This is ideal for embedded machines
with little storage, or having a single machine that will
keep all the data in a single repository.
Note: This option is not supported with latency tracer plugins:
wakeup, wakeup_rt, irqsoff, preemptoff and preemptirqsoff
-V cid:port
If recording on a guest VM and the host is running trace-cmd
listen with the -V option as well, or if this is recording on
the host, and a guest in running trace-cmd listen with the -V
option, then connect to the listener (the same as connecting
with the -N option via the network). This has the same
limitations as the -N option above with respect to latency
tracer plugins.
-t
This option is used with -N, when there’s a need to send the
live data with TCP packets instead of UDP. Although TCP is
not nearly as fast as sending the UDP packets, but it may be
needed if the network is not that reliable, the amount of
data is not that intensive, and a guarantee is needed that
all traced information is transfered successfully.
-q | --quiet
For use with recording an application. Suppresses normal
output (except for errors) to allow only the application’s
output to be displayed.
--date
With the --date option, "trace-cmd" will write timestamps
into the trace buffer after it has finished recording. It
will then map the timestamp to gettimeofday which will allow
wall time output from the timestamps reading the created
trace.dat file.
--max-graph-depth depth
Set the maximum depth the function_graph tracer will trace
into a function. A value of one will only show where
userspace enters the kernel but not any functions called in
the kernel. The default is zero, which means no limit.
--cmdlines-size size
Set the number of entries the kernel tracing file
"saved_cmdlines" can contain. This file is a circular buffer
which stores the mapping between cmdlines and PIDs. If full,
it leads to unresolved cmdlines ("<...>") within the trace.
The kernel default value is 128.
--module module
Filter a module’s name in function tracing. It is equivalent
to adding :mod:module after all other functions being
filtered. If no other function filter is listed, then all
modules functions will be filtered in the filter.
'--module snd' is equivalent to '-l :mod:snd'
'--module snd -l "*jack*"' is equivalent to '-l "*jack*:mod:snd"'
'--module snd -n "*"' is equivalent to '-n :mod:snd'
--proc-map
Save the traced process address map into the trace.dat file.
The traced processes can be specified using the option -P, or
as a given command.
--profile
With the --profile option, "trace-cmd" will enable tracing
that can be used with trace-cmd-report(1) --profile option.
If a tracer -p is not set, and function graph depth is
supported by the kernel, then the function_graph tracer will
be enabled with a depth of one (only show where userspace
enters into the kernel). It will also enable various
tracepoints with stack tracing such that the report can show
where tasks have been blocked for the longest time.
See trace-cmd-profile(1) for more details and examples.
-G
Set interrupt (soft and hard) events as global (associated to
CPU instead of tasks). Only works for --profile.
-H event-hooks
Add custom event matching to connect any two events together.
When not used with --profile, it will save the parameter and
this will be used by trace-cmd report --profile, too. That
is:
trace-cmd record -H hrtimer_expire_entry,hrtimer/hrtimer_expire_exit,hrtimer,sp
trace-cmd report --profile
Will profile hrtimer_expire_entry and hrtimer_expire_ext times.
See trace-cmd-profile(1) for format.
-S
(for --profile only) Only enable the tracer or events
speficied on the command line. With this option, the
function_graph tracer is not enabled, nor are any events
(like sched_switch), unless they are specifically specified
on the command line (i.e. -p function -e sched_switch -e
sched_wakeup)
--temp directory
When trace-cmd is recording the trace, it records the per CPU
data into a separate file for each CPU. At the end of the
trace, these files are concatenated onto the final trace.dat
file. If the final file is on a network file system, it may
not be appropriate to copy these temp files into the same
location. --temp can be used to tell trace-cmd where those
temp files should be created.
--ts-offset offset
Add an offset for the timestamp in the trace.dat file. This
will add a offset option into the trace.dat file such that a
trace-cmd report will offset all the timestamps of the events
by the given offset. The offset is in raw units. That is, if
the event timestamps are in nanoseconds the offset will also
be in nanoseconds even if the displayed units are in
microseconds.
--tsync-interval
Set the loop interval, in ms, for timestamps synchronization
with guests: If a negative number is specified, timestamps
synchronization is disabled If 0 is specified, no loop is
performed - timestamps offset is calculated only twice, at
the beginning and at the end of the trace. Timestamps
synchronization with guests works only if there is support
for VSOCK.
--tsc2nsec
Convert the current clock to nanoseconds, using tsc
multiplier and shift from the Linux kernel’s perf interface.
This option does not change the trace clock, just assumes
that the tsc multiplier and shift are applicable for the
selected clock. You may use the "-C tsc2nsec" clock, if not
sure what clock to select.
--stderr
Have output go to stderr instead of stdout, but the output of
the command executed will not be changed. This is useful if
you want to monitor the output of the command being executed,
but not see the output from trace-cmd.
--poll
Waiting for data to be available on the trace ring-buffers
may trigger IPIs. This might generate unacceptable trace
noise when tracing low latency or real time systems. The poll
option forces trace-cmd to use O_NONBLOCK. Traces are
extracted by busy waiting, which will hog the CPUs, so only
use when really needed.
--name
Give a specific name for the current agent being processed.
Used after -A to give the guest being traced a name. Useful
when using the vsocket ID instead of a name of the guest.
--verbose[=level]
Set the log level. Supported log levels are "none",
"critical", "error", "warning", "info", "debug", "all" or
their identifiers "0", "1", "2", "3", "4", "5", "6". Setting
the log level to specific value enables all logs from that
and all previous levels. The level will default to "info" if
one is not specified.
Example: enable all critical, error and warning logs
trace-cmd record --verbose=warning
--file-version
Desired version of the output file. Supported versions are 6
or 7.
--compression
Compression of the trace output file, one of these strings
can be passed:
'any' - auto select the best available compression algorithm
'none' - do not compress the trace file
'name' - the name of the desired compression algorithms. Available algorithms can be listed with
trace-cmd list -c
--proxy vsocket
Use a vsocket proxy to reach the agent. Acts the same as -A
(for an agent) but will send the proxy connection to the
agent. It is expected to run on a privileged guest that the
host is aware of (as denoted by the cid in the -P option for
the agent).
--daemonize Run trace-cmd in the background as a daemon after
recording has started. Creates a pidfile at
/var/run/trace-cmd-record.pid with the pid of trace-cmd during
the recording.
The basic way to trace all events:
# trace-cmd record -e all ls > /dev/null
# trace-cmd report
trace-cmd-13541 [003] 106260.693809: filemap_fault: address=0x128122 offset=0xce
trace-cmd-13543 [001] 106260.693809: kmalloc: call_site=81128dd4 ptr=0xffff88003dd83800 bytes_req=768 bytes_alloc=1024 gfp_flags=GFP_KERNEL|GFP_ZERO

ls-13545 [002] 106260.693818: sys_exit_write: 0x1
To use the function tracer with sched switch tracing:
# trace-cmd record -p function -e sched_switch ls > /dev/null
# trace-cmd report
ls-13587 [002] 106467.860310: function: hrtick_start_fair <-- pick_next_task_fair
ls-13587 [002] 106467.860313: sched_switch: prev_comm=trace-cmd prev_pid=13587 prev_prio=120 prev_state=R ==> next_comm=trace-cmd next_pid=13583 next_prio=120
trace-cmd-13585 [001] 106467.860314: function: native_set_pte_at <-- __do_fault
trace-cmd-13586 [003] 106467.860314: function: up_read <-- do_page_fault
ls-13587 [002] 106467.860317: function: __phys_addr <-- schedule
trace-cmd-13585 [001] 106467.860318: function: _raw_spin_unlock <-- __do_fault

trace-cmd-13586 [003] 106467.860322: function: down_read_trylock <-- do_page_fault
Here is a nice way to find what interrupts have the highest
latency:
# trace-cmd record -p function_graph -e irq_handler_entry -l do_IRQ sleep 10
# trace-cmd report
<idle>-0 [000] 157412.933969: funcgraph_entry: | do_IRQ() {
