|
|||
|
||||
- Using the logger to output kdump log messages
|
||||
|
||||
Currently, kdump messages are printed with the 'echo' command or redirect
|
||||
to console, and which does not support to output kdump messages according
|
||||
to the log level.
|
||||
You can configure the kdump log level for the first kernel in the
|
||||
/etc/sysconfig/kdump. For example:
|
||||
|
||||
That is not convenient to debug kdump issues, we usually need to capture
|
||||
additional debugging information via the modification of the options or the
|
||||
scripts like kdumpctl, mkdumprd, etc. Because there is no complete debugging
|
||||
messages, which could waste valuable time.
|
||||
KDUMP_STDLOGLVL=3
|
||||
KDUMP_SYSLOGLVL=0
|
||||
KDUMP_KMSGLOGLVL=0
|
||||
|
||||
To cope with this challenging, we introduce the logger to output the kdump
|
||||
messages according to the log level, and provide a chance to save logs to
|
||||
the journald if the journald service is available, and then dump all logs
|
||||
to a file, otherwise dump the logs with the dmesg to a file.
|
||||
The above configurations indicate that kdump messages will be printed
|
||||
to the console, and the KDUMP_STDLOGLVL is set to 3(info), but the
|
||||
KDUMP_SYSLOGLVL and KDUMP_KMSGLOGLVL are set to 0(no logging). This
|
||||
is also the current default log levels in the first kernel.
|
||||
|
||||
Logging is controlled by following global variables:
|
||||
- @var kdump_stdloglvl - logging level to standard error (console output)
|
||||
- @var kdump_sysloglvl - logging level to syslog (by logger command)
|
||||
- @var kdump_kmsgloglvl - logging level to /dev/kmsg (only for boot-time)
|
||||
If any of the variables is not set, this function set it to default:
|
||||
- @var kdump_stdloglvl=4 (info)
|
||||
- @var kdump_sysloglvl=4 (info)
|
||||
- @var kdump_kmsgloglvl=0 (no logging)
|
||||
In the second kernel, you can add the 'rd.kdumploglvl=X' option to the
|
||||
KDUMP_COMMANDLINE_APPEND in the /etc/sysconfig/kdump so that you can also
|
||||
set the log levels for the second kernel. The 'X' represents the logging
|
||||
levels, the default log level is 3(info) in the second kernel, for example:
|
||||
|
||||
Logging levels: fatal(1),error(2),warn(3),info(4),debug(5),trace(6)
|
||||
# cat /etc/sysconfig/kdump |grep rd.kdumploglvl
|
||||
KDUMP_COMMANDLINE_APPEND="irqpoll nr_cpus=1 reset_devices cgroup_disable=memory mce=off numa=off udev.children-max=2 panic=10 acpi_no_memhotplug transparent_hugepage=never nokaslr hest_disable novmcoredd rd.kdumploglvl=3"
|
||||
|
||||
We can easily configure the above variables in the /etc/sysconfig/kdump. For
|
||||
example:
|
||||
kdump_sysloglvl=5
|
||||
kdump_stdloglvl=5
|
||||
Logging levels: no logging(0), error(1),warn(2),info(3),debug(4)
|
||||
|
||||
The above configurations indicate that kdump messages will be printed to the
|
||||
console and journald if the journald service is enabled.
|
||||
The ERROR level designates error events that might still allow the application
|
||||
to continue running.
|
||||
|
||||
The WARN level designates potentially harmful situations.
|
||||
|
||||
The INFO level designates informational messages that highlight the progress
|
||||
of the application at coarse-grained level.
|
||||
|
||||
The DEBUG level designates fine-grained informational events that are most
|
||||
useful to debug an application.
|
||||
|
||||
Note: if you set the log level to 0, that will disable the logs at the
|
||||
corresponding log level, which indicates that it has no log output.
|
||||
|
||||
At present, the logger works in both the first kernel(kdump service debugging)
|
||||
and the second kernel.
|
||||
|
||||
In the first kernel, you can find the historical logs with the journalctl
|
||||
command and check kdump service debugging information. In addition, the
|
||||
'kexec -d' debugging messages are also saved to /var/log/kdump.log in the
|
||||
first kernel. For example:
|
||||
|
||||
[root@ibm-z-109 ~]# ls -al /var/log/kdump.log
|
||||
-rw-r--r--. 1 root root 63238 Oct 28 06:40 /var/log/kdump.log
|
||||
|
||||
If you want to get the debugging information of building kdump initramfs, you
|
||||
can enable the '--debug' option for the dracut_args in the /etc/kdump.conf, and
|
||||
then rebuild the kdump initramfs as below:
|
||||
|
||||
# systemctl restart kdump.service
|
||||
|
||||
That will rebuild the kdump initramfs and gerenate some logs to journald, you
|
||||
can find the dracut logs with the journalctl command.
|
||||
|
||||
In the second kernel, kdump will automatically put the kexec-dmesg.log to a same
|
||||
directory with the vmcore, the log file includes the debugging messages like dmesg
|
||||
and journald logs. For example:
|
||||
|
||||

If you want to get more debugging information in the second kernel, you can add
|
||||
the 'rd.debug' option to the KDUMP_COMMANDLINE_APPEND in the /etc/sysconfig/kdump,
|
||||
and then reload them in order to make the changes take effect.
|
||||
|
||||
In addition, you can also add the 'rd.memdebug=X' option to the KDUMP_COMMANDLINE_APPEND
|
||||
in the /etc/sysconfig/kdump in order to output the additional information about
|
||||
kernel module memory consumption during loading.
|
||||
|
||||
For more details, please refer to the /etc/sysconfig/kdump, or the man page of
|
||||
dracut.cmdline and kdump.conf.
