Overview

The core dump GET API retrieves all of the core dumps on the cluster or a node. The core dump DELETE API deletes a specified core dump. Some fields are only populated for core dump type "kernel". Refer to the model for further information. Fields will not be displayed if they are not populated. A core can be deleted even if the core is in the process of being saved.
