VDOStatus - command /usr/bin/vdo status

Module for parsing the output of command vdo status. The bulk of the content is split on the colon and keys are kept as is.

class insights.parsers.vdo_status.VDOStatus(context, extra_bad_lines=None)[source]

Bases: insights.core.CommandParser, insights.core.YAMLParser

Class for parsing vdo status command output.
