DESCRIPTION

 

devlink health show - Show status and configuration on all supported reporters on all devlink devices.

DEV - specifies the devlink device.

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

 

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.

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

 

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.

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

 

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.

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

 

devlink health set - Enable the user to configure:

1) grace_period [msec] - Time interval between consecutive auto recoveries.

2) auto_recover [true/false] - Indicates whether the devlink should execute automatic recover on error.

Please note that this command is not supported on a reporter which doesn't support a recovery method.

DEV - specifies the devlink device.

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