Introduction of Kdump graphical configuration tools from RHEL6.2 and SUSE11SP2 systems

System-config-kdump mainly includes the basic settings, target settings, filtering settings, advanced settings four parts, respectively from the case to explain; Yast2 Kdump mainly includes startup options, dump filtering, dump targets, http://www.aliyun.com/ Zixun/aggregation/18686.html "> Five parts, such as mail notification, advanced configuration, explain it separately from the instance.

As we all know, RHEL and SUSE are the two most popular enterprise versions of Linux today, especially in the cloud computing server area. For interface users, the relatively boring kdump command-line terminal configuration file, they need to see a simple and convenient graphical configuration tool as a stunt killer. The following is an example of the IBM power architecture and RHEL6.2, SLES11SP2 system, which explains how the graphical tools make the user of the interface easy and straightforward.

RHEL6.2 kdump Graphics Configuration tool: System-config-kdump. It needs to install the System-config-kdump RPM package. System-config-kdump mainly includes the basic settings, target settings, filtering settings, advanced settings Four parts, the following through a specific example to introduce the relevant desktop configuration. In addition, the tool requires root permission to be started in the interface window. There are two ways to start the graphics tool (kernel dump configuration): (1) on the Panel main menu, select System-> administration-> Kernel crash says. (2) Type the System-config-kdump command in the GNOME terminal.

Basic operations

After the System-config-kdump package is installed, if the tool is already disabled, you must first enable it to perform the following configuration (click the Enable button). The Apply button allows you to change the configuration to take effect. The Reload button is to restore your operational changes to the original state. Figure 1 below,

Figure 1. Basic settings

Basic settings. Kdump basic settings, including total associated memory. Target settings. Save the kernel dump to the local disk or connect to the server remotely via Ssh/nfs, select the path. Filter settings. Filtering level. Advanced Settings. Give kernel command-line arguments, select dump-time behavior, and configure the core collector.

Basic settings

In the basic settings, the total memory of the system is introduced, the memory currently reserved for Kdump, the memory reserved for Kdump, the available memory after reservation, etc. As shown in Figure 1 above, automatic Kdump memory settings automatically select the optimal parameter configuration based on system memory. There are several fields for manual kdump memory settings:

Total system Memory: overall memory. Current Kdump Memory: The actual memory that is currently reserved for kdump. New kdump Memory: Manually set the kdump reserved memory, which requires manual input. Usable Memory: Available memory
