DESCRIPTION <\/a> <\/h2>\n

devlink health show – Show status and configuration on all supported reporters.<\/b>
Displays info about reporters registered on devlink devices and ports.<\/p>\n

DEV<\/i> – specifies the devlink device.
DEV\/PORT_INDEX<\/i> – specifies the devlink port.<\/p>\n

REPORTER<\/i> – specifies the reporter\u2019s name registered on specified devlink device or port.<\/p>\n

devlink health recover – Initiate a recovery operation on a reporter.<\/b>
This action performs a recovery and increases the recoveries counter on success.<\/p>\n

DEV<\/i> – specifies the devlink device.
DEV\/PORT_INDEX<\/i> – specifies the devlink port.<\/p>\n

REPORTER<\/i> – specifies the reporter\u2019s name registered on specified devlink device or port.<\/p>\n

devlink health diagnose – Retrieve diagnostics data on a reporter.<\/b>
DEV<\/i> – specifies the devlink device.
DEV\/PORT_INDEX<\/i> – specifies the devlink port.<\/p>\n

REPORTER<\/i> – specifies the reporter\u2019s name registered on specified devlink device or port.<\/p>\n

devlink health test – Trigger a test event on a reporter.<\/b>
DEV<\/i> – specifies the devlink device.<\/p>\n

REPORTER<\/i> – specifies the reporter\u2019s name registered on the devlink device.<\/p>\n

devlink health dump show – Display the last saved dump.<\/b>
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\u2019s request.<\/p>\n

DEV<\/i> – specifies the devlink device.
DEV\/PORT_INDEX<\/i> – specifies the devlink port.<\/p>\n

REPORTER<\/i> – specifies the reporter\u2019s name registered on specified devlink device or port.<\/p>\n

devlink health dump clear – Delete the saved dump.<\/b>
Deleting the saved dump enables a generation of a new dump on
the next “devlink health dump show” command.<\/p>\n

DEV<\/i> – specifies the devlink device.
DEV\/PORT_INDEX<\/i> – specifies the devlink port.<\/p>\n

REPORTER<\/i> – specifies the reporter\u2019s name registered on specified devlink device or port.<\/p>\n

devlink health set – Configure health reporter.<\/b>
Please note that some params are not supported on a reporter which doesn\u2019t support a recovery or dump method.<\/p>\n

DEV<\/i> – specifies the devlink device.
DEV\/PORT_INDEX<\/i> – specifies the devlink port.<\/p>\n

REPORTER<\/i> – specifies the reporter\u2019s name registered on specified devlink device or port.
grace_period<\/b> MSEC<\/i><\/p>\n

Time interval between consecutive auto recoveries.<\/p>\n

auto_recover<\/b> { true<\/b> | false<\/b> }<\/p>\n

Indicates whether the devlink should execute automatic recover on error.<\/p>\n

auto_dump<\/b> { true<\/b> | false<\/b> }<\/p>\n

Indicates whether the devlink should execute automatic dump on error.<\/p>\n
