NAME
       tplist - Display kernel tracepoints or USDT probes and their formats.

SYNOPSIS
       tplist [-p PID] [-l LIB] [-v] [filter]

DESCRIPTION
       tplist  lists all kernel tracepoints, and can optionally print out the tracepoint format; namely, the
       variables that you can trace when the tracepoint is hit.	 tplist can also list USDT  probes  embedded
       in  a specific library or executable, and can list USDT probes for all the libraries loaded by a spe‐
       cific process.  These features are usually used in conjunction with the argdist and/or trace tools.

       On a typical system, accessing the tracepoint list and format requires root.  However, accessing USDT
       probes does not require root.

OPTIONS
       -p PID Display the USDT probes from all the libraries loaded by the specified process.

       -l LIB Display the USDT probes from the specified library or executable. If the librar or  executable
	      can be found in the standard paths, a full path is not required.

       -v     Increase	the  verbosity level. Can be used to display the variables, locations, and arguments
	      of tracepoints and USDT probes.

       [filter]
	      A wildcard expression that specifies which tracepoints  or  probes  to  print.   For  example,
	      block:*  will print all block tracepoints (block:block_rq_complete, etc.). Regular expressions
	      are not supported.

EXAMPLES
       Print all kernel tracepoints:
	      # tplist

       Print all net tracepoints with their format:
	      # tplist -v 'net:*'

       Print all USDT probes in libpthread:
	      $ tplist -l pthread

       Print all USDT probes in process 4717 from the libc provider:
	      $ tplist -p 4717 'libc:*'

       Print all the USDT probes in the node executable:
	      $ tplist -l node
