# Introduction
This module writes out a traceback to a file when a chosen signal (by default
`SIGUSR1`) is received. It can be useful to diagnose cases where Prosody is
unresponsive.
# Configuration
`debug_traceback_filename`
: The name of the file to write the traceback to. Some variables
are supported, see [mod_log_ringbuffer] docs for more info. Defaults
to `{paths.data}/traceback-{pid}-{count}.log`.
`debug_traceback_signal`
: The name of the signal to listen for. Defaults to `SIGUSR1`.
# Compatibility
Prosody 0.12 or later.
