    :How do I enable the kdump service on a Linux instance?

    Last Updated:Aug 19, 2024

    Introduction

    The kdump service can capture kernel errors to analyze kernel crashes. This topic describes how to enable the kdump service on a Linux Elastic Compute Service (ECS) instance.

    Note

    For information about the kdump service, see the kdump documentation.

    Procedure

    The kdump service consumes memory space in the operating system. The corresponding kdump.service system service in user mode may affect the system startup speed. Therefore, the kdump service may be disabled by default in specific Linux distributions. Cloud Assistant can manage the kdump service in most operating system versions. You can use Cloud Assistant to enable, view, and disable the kdump service. In the following example, CentOS 7.9 is used.

    1. Enable the kdump service.

    acs-plugin-manager --exec --plugin ecs_dump_config --params --enable
