NAME
devlink-health - devlink health configuration
SYNOPSIS
devlink [ OPTIONS ] health { COMMAND | help }
OPTIONS := { -V[ersion] | -n[no-nice-names] }
devlink health show [ DEV ] [ sensor NAME ]
devlink health sensor set DEV name NAME [ action NAME { active | inactive } ]"
devlink health action set DEV name NAME period PERIOD count COUNT fail { ignore | down }
devlink health action reinit DEV name NAME
devlink health help
DESCRIPTION
devlink-health tool allows user to configure the way driver treats unexpected status. The tool allows configuration of the sensors that can trigger health activity. Set for each sensor the follow up operations, such as,
reset and dump of info. In addition, set the health activity termination action.
devlink health show - Display devlink health sensors and actions attributes
DEV - Specifies the devlink device to show. If this argument is omitted, all devices are listed.
Format is:
BUS_NAME/BUS_ADDRESS
sensor NAME - Specifies the devlink sensor to show.
devlink health sensor set - sets devlink health sensor attributes
DEV Specifies the devlink device to show.
name NAME
Name of the sensor to set.
action NAME { active | inactive }
Specify which actions to activate and which to deactivate once a sensor was triggered. actions can be dump, reset, etc.
devlink health action set - sets devlink action attributes
DEV Specifies the devlink device to set.
name NAME
Specifies the devlink action to set.
period PERIOD
The period on which we limit the amount of performed actions, measured in seconds.
count COUNT
The maximum amount of actions performed in a limit time frame.
fail { ignore | down }
Specify the behavior once count limit was reached.
ignore - Ignore errors without execution of any action.
down - Driver will remain in nonoperational state.
devlink health action reinit - reset devlink action attributes (period, count, fail, etc)
DEV Specifies the devlink device to set.
name NAME
Specifies the devlink action to set.
EXAMPLES
devlink health show
Shows the health state of all devlink devices on the system.
devlink health show pci/0000:01:00.0
Shows the health state of specified devlink device.
devlink health sensor set pci/0000:01:00.0 name TX_COMP_ERROR action reset off action dump on
Sets TX_COMP_ERROR sensor parameters for a specific device.
devlink health action set pci/0000:01:00.0 name reset period 3600 count 5 fail ignore
Sets health attributes for reset action.
