# trace-cmd-stat(1)

show the status of the tracing (ftrace) system

## NAME

trace-cmd-stat - show the status of the tracing (ftrace) system

## SYNOPSIS

**trace-cmd stat** \[*OPTIONS*\]

## DESCRIPTION

The [trace-cmd(1)](/trace-cmd/1.md) stat displays the various status of the tracing (ftrace) system. The status that it shows is:

**Instances:** List all configured ftrace instances.

**Tracer:** if one of the tracers (like function\_graph) is active. Otherwise nothing is displayed.

**Events:** Lists the events that are enable.

**Event filters:** Shows any filters that are set for any events

**Function filters:** Shows any filters for the function tracers

**Graph functions:** Shows any functions that the function graph tracer should graph

**Buffers:** Shows the trace buffer size if they have been expanded. By default, tracing buffers are in a compressed format until they are used. If they are compressed, the buffer display will not be shown.

**Trace clock:** If the tracing clock is anything other than the default "local" it will be displayed.

**Trace CPU mask:** If not all available CPUs are in the tracing CPU mask, then the tracing CPU mask will be displayed.

**Trace max latency:** Shows the value of the trace max latency if it is other than zero.

**Kprobes:** Shows any kprobes that are defined for tracing.

**Uprobes:** Shows any uprobes that are defined for tracing.

**Error log:** Dump the content of ftrace error\_log file.

## OPTIONS

- **-B** *buffer-name*

  Display the status of a given buffer instance. May be specified more than once to display the status of multiple instances.

- **-t**

  If **-B** is also specified, show the status of the top level tracing directory as well as the instance(s).

- **-o**

  Display the all the options along with their values. If they start with "no", then the option is disabled.
