TRACE-CMD-STOP(1)														 TRACE-CMD-STOP(1)

trace-cmd-stop - stop the Ftrace Linux kernel tracer from writing to the ring buffer. SYNOPSIS
trace-cmd stop DESCRIPTION
The trace-cmd(1) stop is a complement to trace-cmd-start(1). This will disable Ftrace from writing to the ring buffer. This does not stop the overhead that the tracing may incur. Only the updating of the ring buffer is disabled, the Ftrace tracing may still be inducing overhead. After stopping the trace, the trace-cmd-extract(1) may strip out the data from the ring buffer and create a trace.dat file. The Ftrace pseudo file system may also be examined. To disable the tracing completely to remove the overhead it causes, use trace-cmd-reset(1). But after a reset is performed, the data that has been recorded is lost. SEE ALSO
trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-start(1), trace-cmd-extract(1), trace-cmd-reset(1), trace-cmd-split(1), trace-cmd-list(1), trace-cmd-listen(1) AUTHOR

trace-cmd - interacts with Ftrace Linux kernel internal tracer SYNOPSIS
The trace-cmd(1) command interacts with the Ftrace tracer that is built inside the Linux kernel. It interfaces with the Ftrace specific files found in the debugfs file system under the tracing directory. A COMMAND must be specified to tell trace-cmd what to do. COMMANDS
record - record a live trace and write a trace.dat file to the local disk or to the network. report - reads a trace.dat file and converts the binary data to a ASCII text readable format. hist - show a histogram of the events. options - list the plugin options that are available to *report* start - start the tracing without recording to a trace.dat file. stop - stop tracing (only disables recording, overhead of tracer is still in effect) extract - extract the data from the kernel buffer and create a trace.dat file. reset - disables all tracing and gives back the system performance. (clears all data from the kernel buffers) split - splits a trace.dat file into smaller files. list - list the available plugins or events that can be recorded. listen - open up a port to listen for remote tracing connections. restore - restore the data files of a crashed run of trace-cmd record stack - run and display the stack tracer check-events - parse format strings for all trace events and return whether all formats are parseable OPTIONS
-h, --help Display the help text. Other options see the man page for the corresponding command. SEE ALSO
