Linux: Partition Device

Description

The linux.partition_device_v1 test is used to check the information associated with partitions on the local system.

The partition_object is used by a partition_test to define which partitions on the local system should be collected.

The partition_state element defines the different information associated with a partition. This includes the name, filesystem type, mount options, total space, space used, and space left.

Technical Details

Artifact Parameters

linux.partition_device_v1

Name	Type	Description
mount_point	string	Filesystem mount point being tested. Cannot be blank.
