.SH NAME | ||
tplist \- Display kernel tracepoints and their format. | ||
.SH SYNOPSIS | ||
.B tplist [-v] [tracepoint] | ||
.SH 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. This | ||
is usually used in conjunction with the argdist and/or trace tools. | ||
|
||
On a typical system, accessing the tracepoint list and format requires root. | ||
.SH OPTIONS | ||
.TP | ||
\-v | ||
Display the variables associated with the tracepoint or tracepoints. | ||
.TP | ||
[tracepoint] | ||
A wildcard expression that specifies which tracepoints to print. For example, | ||
block:* will print all block tracepoints (block:block_rq_complete, etc.). | ||
Regular expressions are not supported. | ||
.SH EXAMPLES | ||
.TP | ||
Print all kernel tracepoints: | ||
# | ||
.B tplist | ||
