tplist(8) System Manager's Manual tplist(8)

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
