DEV - specifies the devlink device.
DEV/PORT_INDEX - specifies the devlink port.

REPORTER - specifies the reporter's name registered on specified devlink device or port.

devlink health dump show - Display the last saved dump.

devlink health saves a single dump per reporter. If an dump is

not already stored by the Devlink, this command will generate a new

reporter reports on an error or manually at the user's request.

DEV - specifies the devlink device.
DEV/PORT_INDEX - specifies the devlink port.

REPORTER - specifies the reporter's name registered on specified devlink device or port.

devlink health dump clear - Delete the saved dump.

Deleting the saved dump enables a generation of a new dump on

the next "devlink health dump show" command.

DEV - specifies the devlink device.
DEV/PORT_INDEX - specifies the devlink port.

REPORTER - specifies the reporter's name registered on specified devlink device or port.

devlink health set - Configure health reporter.

Please note that some params are not supported on a reporter which doesn't support a recovery or dump method.

DEV - specifies the devlink device.
DEV/PORT_INDEX - specifies the devlink port.

REPORTER - specifies the reporter's name registered on specified devlink device or port.

grace_period MSEC
Time interval between consecutive auto recoveries.
