analyzevmcore(8) Support Utilities Manual analyzevmcore(8)NAMEanalyzevmcore - Creates an analysis file for kernel cores
SYNOPSISanalyzevmcore [OPTIONS]
DESCRIPTION
Creates an analysis file (nts_analyzevmcore_<CORE_DATE>.txt) for all
kernel cores found on the system. This analysis file is automatically
copied to /var/log, and included in supportconfig's crash.txt file for
further analysis by SUSE and Novell Technical Services.
In order to create the analysis, this script requires the kernel
(vmlinux-*) and the debuginfo kernel (vmlinux-*.debug) which match the
kernel version which created the core.
KERNEL VERSION
The kernel version is determined automatically if a README.txt file
exists in the core directory. This file is typically created during
core generation, and should contain the following string:
Kernel version : $(uname -r)
If the README.txt is missing, the kernel version is taken from an
existing kernel file (vmlinux-*) found in the core directory (also typ‐
ically copied into the core directory during core creation). If no ker‐
nel file is found in the core directory, the kernel version is taken
from the currently running kernel. NOTE - If this is incorrect, the
analysis will either fail, or be incomplete.
To override the automatic kernel version detection process, a
README.txt can be manually created in the core directory. In this case,
the kernel version must be specified exactly as
Kernel version : <correct version, i.e. 3.0.13-0.27-default>
The kernel version can also be specified on the command line through
using the -k option to point to a specific kernel file.
DEBUGINFO KERNEL
This debuginfo kernel contains symbols stripped from the normally run‐
ning kernel. These symbols are required for core analysis. The debug‐
info kernel will only be found in the following ways:
1. If the kernel-*-debuginfo RPM is installed on the system, the
vmlinux-*.debug file will be found in /usr/lib/debug/boot. The
kernel-*-debuginfo RPM can be installed through the Debuginfo
update channel using:
zypper in kernel-<FLAVOR>-debuginfo
For additional information on installing the Debuginfo update
channel, see: http://www.suse.com/support/kb/doc.php?id=3074997
2. If a debuginfo kernel is not found in /usr/lib/debug/boot, the
vmlinux-*.debug file will also be found if it exists in the same
same directory as the normal kernel, or the same directory as
the core. As this is not normally the case, the vmlinux-*.debug
file will first need to be extracted from the kernel-*-debuginfo
RPM. This can be done manually, or automatically through the
following parameter:
-d [kernel-*-debuginfo.rpm]
The correct kernel-*-debuginfo RPM can be downloaded through the
Novell FileFinder, or through the patch database (using valid
update credentials) at the following urls:
FileFinder: http://download.novell.com/patch/finder
Patch Database: http://download.novell.com/patch/psdb
OPTIONS-h This screen
-c directory
Analyze the specified vmcore directory, rather than all cores
found on the system.
-d RPM This option extracts the vmlinux-*.debug file from the specified
kernel-*-debuginfo RPM into the core directory
-k vmlinux
The vmlinux-[version] file which created the core. This can
always be found in /boot, and must match the kernel version
which created the core. If this is in the current directory
(e.g. /var/crash<date>), this parameter can be omitted.
-r Remove and recreate existing analysis files.
