NAME
$prog - Dump and/or format asterisk coredump files
SYNOPSIS
$prog [ --help ] [ --running | --RUNNING ] [ --latest ]
[ --tarball-coredumps ] [ --delete-coredumps-after ]
[ --tarball-results ] [ --delete-results-after ]
[ --tarball-config ] [ --tarball-uniqueid="<uniqueid>" ]
[ --no-default-search ] [ --append-coredumps ]
[ --asterisk-bin="path" ]
[ <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. The coredump will be written to /tmp if
$OUTPUTDIR is not defined.
--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 coredumps processed, their
results txt files and copies of /etc/os-release,
/usr/sbin/asterisk, /usr/lib(64)/libasterisk* and
/usr/lib(64)/asterisk as those files are needed to properly
examine the coredump. The file will be named
$OUTPUTDIR/asterisk.<timestamp>.coredumps.tar.gz or
$OUTPUTDIR/asterisk-<uniqueid>.coredumps.tar.gz if
--tarball-uniqueid was specified.
WARNING: This file could 1gb in size!
Mutually exclusive with --tartball-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 --tartball-coredumps
--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-config
Adds the contents of /etc/asterisk to the tarball created
with --tarball-coredumps or --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.
--asterisk-binary
Path to the asterisk binary. Default: look for asterisk
in the PATH.
<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 $prog.
$OUTPUTDIR can be read from the current environment or from the
ast_debug_tools.conf file described below. If not specified,
work products are placed in the same directory as the core file.
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.

# 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.
