ast_coredumper - Dump and/or format asterisk coredump files
SYNOPSIS
ast_coredumper [ --help ] [ --running | --RUNNING ] [ --latest ]
[ --tarball-coredumps ] [ --delete-coredumps-after ]
[ --tarball-results ] [ --delete-results-after ]
[ --tarball-uniqueid="<uniqueid>" ]
[ --no-default-search ] [ --append-coredumps ]
[ <coredump> | <pattern> ... ]
DESCRIPTION
Extracts backtraces and lock tables from Asterisk coredump files.
For each coredump found, 4 new result files are created:
- <coredump>.brief.txt: The output of "thread apply all bt".
- <coredump>.thread1.txt: The output of "thread apply 1 bt full".
- <coredump>.full.txt: The output of "thread apply all bt full".
- <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.
Optional features:
- The running asterisk process can be suspended and dumped.
- The coredumps can be merged into a tarball.
- The coredumps can be deleted after processing.
- The results files can be merged into a tarball.
- The results files can be deleted after processing.
Options:
--help
Print this help.
--running
Create a coredump from the running asterisk instance and
process it along with any other coredumps found (if any).
WARNING: This WILL interrupt call processing. You will be
asked to confirm.
--RUNNING
Same as --running but without the confirmation prompt.
DANGEROUS!!
--latest
Process only the latest coredump from those specified (based
on last-modified time). If a dump of the running process was
requested, it is always included in addition to the latest
from the existing coredumps.
--tarball-coredumps
Creates a gzipped tarball of all coredumps processed.
The tarball name will be:
/tmp/asterisk.<timestamp>.coredumps.tar.gz
--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:
/tmp/asterisk.<timestamp>.results.tar.gz
--delete-results-after
Deletes all processed results regardless of whether
a tarball was created. It probably doesn't make sense
to use this option unless you have also specified
--tarball-results.
--tarball-uniqueid="<uniqueid>"
Normally DATEFORMAT is used to make the tarballs unique
but you can use your own unique id in the tarball names
such as the Jira issue id.
--no-default-search
Ignore COREDUMPS from the config files and process only
coredumps listed on the command line (if any) and/or
the running asterisk instance (if requested).
--append-coredumps
Append any coredumps specified on the command line to the
config file specified ones instead of overriding them.
<coredump> | <pattern>
A list of coredumps or coredump search patterns. Unless
--append-coredumps was specified, these entries will override
those specified in the config files.
Any resulting file that isn't actually a coredump is silently
ignored. If your patterns contains spaces be sure to only
quote the portion of the pattern that DOESN'T contain wildcard
expressions. If you quote the whole pattern, it won't be
expanded.
If --no-default-search is specified and no files are specified
on the command line, then the only the running asterisk process
will be dumped (if requested). Otherwise if no files are
specified on the command line the value of COREDUMPS from
ast_debug_tools.conf will be used. Failing that, the following
patterns will be used:
/tmp/core[-._]asterisk!(*.txt)
/tmp/core[-._]$(hostname)!(*.txt)
NOTES
You must be root to use ast_coredumper.
The script relies on not only bash, but also recent GNU date and
gdb with python support. *BSD operating systems may require
installation of the 'coreutils' and 'devel/gdb' packagess and minor
tweaking of the ast_debug_tools.conf file.
Any files output will have ':' characters changed to '-'. This is
to facilitate uploading those files to Jira which doesn't like the
colons.
FILES
/etc/asterisk/ast_debug_tools.conf
~/ast_debug_tools.conf
./ast_debug_tools.conf
#
# This file is used by the Asterisk debug tools.
# Unlike other Asterisk config files, this one is
# "sourced" by bash and must adhere to bash semantics.
#
# A list of coredumps and/or coredump search patterns.
# Bash extended globs are enabled and any resulting files
# that aren't actually coredumps are silently ignored
# so you can be liberal with the globs.
#
# If your patterns contains spaces be sure to only quote
# the portion of the pattern that DOESN'T contain wildcard
# expressions. If you quote the whole pattern, it won't
# be expanded and the glob characters will be treated as
# literals.
#
# The exclusion of files ending ".txt" is just for
# demonstration purposes as non-coredumps will be ignored
# anyway.
COREDUMPS=(/tmp/core[-._]asterisk!(*.txt) /tmp/core[-._]$(hostname)!(*.txt))
# Date command for the "running" coredump and tarballs.
# DATEFORMAT will be executed to get the timestamp.
# Don't put quotes around the format string or they'll be
# treated as literal characters. Also be aware of colons
# in the output as you can't upload files with colons in
# the name to Jira.
#
# Unix timestamp
#DATEFORMAT='date +%s.%N'
#
# *BSD/MacOS doesn't support %N but after installing GNU
# coreutils...
#DATEFORMAT='gdate +%s.%N'
#
# Readable GMT
#DATEFORMAT='date -u +%FT%H-%M-%S%z'
#
# Readable Local time

<p style="margin: 10px 0 0 0">Whenever collecting information about a deadlock it is useful to have additional information about the threads involved. We can generate this information by attaching to a running Asterisk process and gathering that information. Follow the steps below to collect debug that will be useful to Asterisk developers.</p>
<p style="margin: 10px 0 0 0"> <span>If you can easily reproduce the deadlock, in the Compiler Flags menu of menuselect you should enable </span><strong>DEBUG_THREADS</strong><span>, <strong>MALLOC_DEBUG</strong>, </span><strong>DONT_OPTIMIZE</strong><span>. Then, you need to recompile, re-install, and restart Asterisk before following the steps below. <strong>DEBUG_THREADS</strong> is very resource intensive and can seriously impact performance so you should only use it if you can reproduce the issue quickly. Otherwise, <strong>DONT_OPTIMIZE</strong> is the only option you really need. </span> </p>
