trace-cmd - interacts with Ftrace Linux kernel internal tracer
trace-cmd COMMAND [OPTIONS]
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.
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. 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.
*-h, --help Displace the help text. Other options see the man page for the corresponding command.
