NAME
$prog - Dump and/or format asterisk coredump files
SYNOPSIS
$prog [ --help ] [ --running | --RUNNING ] [ --pid="pid" ]
[ --latest ] [ --OUTPUTDIR="path" ]
[ --libdir="path" ] [ --asterisk-bin="path" ]
[ --gdb="path" ] [ --rename ] [ --dateformat="date options" ]
[ --tarball-coredumps ] [ --delete-coredumps-after ]
[ --tarball-results ] [ --delete-results-after ]
[ --tarball-config ]
[ <coredump> | <pattern> ... ]
DESCRIPTION
Extracts backtraces and lock tables from Asterisk coredump files.
For each coredump found, 5 new result files are created:
- <coredump>-brief.txt: The output of "thread apply all bt".
- <coredump>-full.txt: The output of "thread apply all bt full".
- <coredump>-info.txt: State info like taskprocessors, channels, etc
- <coredump>-locks.txt: If asterisk was compiled with
"DEBUG_THREADS", this file will contain a dump of the locks
table similar to doing a "core show locks" from the asterisk
CLI.
- <coredump>-thread1.txt: The output of "thread apply 1 bt full".
Options:
--help
Print this help.
--running
Create a coredump from the running asterisk instance and
process it.
WARNING: This WILL interrupt call processing. You will be
asked to confirm.
--RUNNING
Same as --running but without the confirmation prompt.
DANGEROUS!!
--pid=<asterisk main process pid>
If you are trying to get a dump of the running asterisk
instance, specifying its pid on the command line will
bypass the complex logic used to figure it out.
--latest
Process only the latest coredump from those specified (based
on last-modified time). Only needed when --running was not
specified and there is more that one coredump matched.
--outputdir=<output directory>
The directory into which output products will be saved.
Default: same directory as coredump
--libdir=<shared libs directory>
The directory where the libasterisk* shared libraries and
the asterisk/modules directory are located. The common
directories like /usr/lib, /usr/lib64, etc are automatically
searches so only use this option when your asterisk install
is non-standard.
--asterisk-bin=<asterisk binary>
Path to the asterisk binary.
Default: look for asterisk in the PATH.
--gdb=<path_to_gdb>
gdb must have python support built-in. Most do.
Default: /usr/bin/gdb
--dateformat=<date options>
Passed to the 'date' utility to construct dates.
The default is '-u +%FT%H-%M-%SZ' which results
in a UTC timestamp.
--rename
Causes the coredump to be renamed using DATEOPTS
and the output files to be named accordingly.
This is the default. To disable renaming, specify
--no-rename
--tarball-coredumps
Creates a gzipped tarball of each coredump processed, their
results txt files, a copy of /etc/os-release, the
asterisk binary, and all modules.
The file will be named like the coredump with '.tar.gz'
appended.
WARNING: This file could be quite large!
Mutually exclusive with --tarball-results
--delete-coredumps-after
Deletes all processed coredumps regardless of whether
a tarball was created.
--tarball-results
Creates a gzipped tarball of all result files produced.
The tarball name will be:
$OUTPUTDIR/asterisk.<timestamp>.results.tar.gz
Mutually exclusive with --tarball-coredumps
--delete-results-after
Deletes all processed results regardless of whether
a tarball was created. It probably does not make sense
to use this option unless you have also specified
--tarball-results.
--tarball-config
Adds the contents of /etc/asterisk to the tarball created
with --tarball-coredumps or --tarball-results.
<coredump> | <pattern>
A list of coredumps or coredump search patterns. These
will override the default and those specified in the config files.
The default pattern is "/tmp/core!(*.txt)"
The "!(*.txt)" tells bash to ignore any files that match
the base pattern and end in ".txt". It$'s not strictly
needed as non asterisk coredumps are always ignored.
NOTES
You must be root to use this program.
All options except "running", "RUNNING" and "pid" can be
specified in the ast_debug_tools.conf file.
Option names must be translated to upper case and their '-'
characters replaced by '_'. Boolean options must be set to
'true' or 'false' (lower case, without the quotes).
Examples:
TARBALL_RESULTS=true
RENAME=false
ASTERISK_BIN=/usr/sbin/asterisk
The script relies on not only bash, but also recent GNU date and
gdb with python support. *BSD operating systems may require
installation of the 'coreutils' and 'devel/gdb' packages and minor
tweaking of the ast_debug_tools.conf file.
Any files output will have ':' characters changed to '-'. This is
to facilitate uploading those files to Jira which doesn't like the
colons.
FILES

source tree for more info.
#@@@HELPEND@@@
# Be careful editing the inline scripts.
# They're space-indented.
# We need the python bit because lock_infos isn't
# a valid symbol in asterisk unless DEBUG_THREADS was
