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	exe‐
       cutable,	 and  can  list	 USDT probes for all the libraries loaded by a specific 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
