USER COMMANDS                                      2016-03-20                                          tplist(8)

       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 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.

       Print all kernel tracepoints:
              # tplist

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

       Print all USDT probes in libpthread:
              $ tplist-lpthread

       Print all USDT probes in process 4717 from the libc provider:
              $ tplist-p4717'libc:*'

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

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

       -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.
