The OS Crash Dump Analyzer module checks the dump configuration of a system, and detects whether an OS crash dump has occurred.
This module also provides the following features:
Displays the current configuration of the system crash dump data, and helps detect OS crash dump files that are saved in the savecore directory
Prints a report that can be used to help analyze the crash dump files
Enables you to send output to one or more email addresses
The OS Crash Dump Analyzer module generates the following types of alarms:
An alert alarm when the module detects that at least one crash dump has occurred
A caution alarm if savecore is disabled, since this situation is not a recommended configuration
A caution alarm for each UNIX or vmcore file the module cannot find
You can configure the alarm thresholds through the Attributes window. For more information on the Attributes window, refer to the Sun Management Center 3.6 User’s Guide.
The data acquisition for the module is based on the dumpadm command. The dumpadm command is not available on the Solaris 2.6 operating environment. Therefore, if the dumpadm tool cannot be found during setup, the module prompts for the location of the savecore directory. The usual location is /var/crash/system_name.
The OS Crash Dump Analyzer displays two tables, the Dump Configuration table and the List of UNIX/vmcore Files table.
The Dump Configuration table displays the values listed in the following table.
Table 2–1 Dump Configuration Table
You can modify the first four fields of the Dump Configuration table using the dumpadm command.
The syntax of the dumpadm command is as follows:
dumpadm [ -nuy ] [ -c content-type ] [ -d dump-device ] [-m min k | min m |min% ] [ -s savecore-dir ] [ -r root-dir ]
The Dump Configuration table does not show the same information on the Solaris 2.6 operating environment. On this operating environment, only the savecore directory and number of crash dumps is given.
The List of UNIX/vmcore Files table gives more information about each crash dump.
