devlink health help
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 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.
