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  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
