DESCRIPTION

   devlink health show - Show status and configuration on all supported reporters.
       Displays info about reporters registered on devlink devices and ports.

       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 recover - Initiate a recovery operation on a reporter.
       This action performs a recovery and increases the recoveries counter on success.

       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 diagnose - Retrieve diagnostics data on a reporter.
       DEV - specifies the devlink device.

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

   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
       dump. The dump can be generated either automatically when a
       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.

       auto_recover { true | false }
              Indicates whether the devlink should execute automatic recover on error.

       auto_dump { true | false }
              Indicates whether the devlink should execute automatic dump on error.
