Display coredump configuration

Availability: This command is available to cluster administrators at the admin privilege level.

Description

The system node coredump config show command displays basic information about a cluster's core dump configuration, such as whether sparse cores are enabled, minimum number of free bytes on the root volume file system that need to be available after saving the core files, maximum number of times the process attempts to generate a core dump when encountering repeated disk failures, maximum number of times the process attempts to save a core dump, the URL to which core dumps are uploaded, and whether core dumps are automatically saved when a node restarts.

Parameters

{ [-fields <fieldname>,…​]

If you specify the -fields <fieldname>, …​ parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.

| [-instance ] }

If you specify the -instance parameter, the command displays detailed information about all fields.

[-node {<nodename>|local}] - Node

If you specify this parameter, the command displays the coredump configuration information of the specified node.

[-sparsecore-enabled {true|false}] - Enable Sparse Cores

If you specify this parameter, the command displays only the coredump information that matches the specified spare core setting. A sparse core omits all memory buffers that contain only user data.

[-min-free {<integer>[KB|MB|GB|TB|PB]}] - Minimum Free Bytes On Root Filesystem

If you specify this parameter, the command displays only the core dump information that matches the specified number of bytes that need to be made available in the root file system after saving the core dump.

[-coredump-attempts <integer>] - Maximum Number Of Attempts to Dump Core

If you specify this parameter, the command displays only the core dump information that matches the specified maximum number of times the system will attempt to generate a core dump when encountering repeated disk failures.

[-save-attempts <integer>] - Maximum Number Attempts to Save Core

If you specify this parameter, the command displays only the coredump information that matches the maximum number of times the system will attempt to save a core dump.

[-save-onstartup {true|false}] - Enable Auto Save of Coredumps on Startup

If you specify this parameter, the command displays only the coredump information that matches the specified configuration of whether the system will automatically start saving the core dump after reboot.

[-upload-location <text>] - URL for Coredump Upload Directory
Note This option is deprecated and might be removed in a future release of Data ONTAP. Use the -uri parameter of the "system node autosupport invoke-core-upload " command instead.

If you specify this parameter, the command displays only the core dump information that matches the specified URL where core dumps are uploaded.

Examples

The following example displays information about the cluster's core dump configuration:
