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. _DEV/PORT_INDEX_ - specifies the devlink port. _REPORTER_ - specifies the reporter's name registered on specified devlink device or port. ### devlink health test - Trigger a test event 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. ## EXAMPLES devlink health show List status and configuration of available reporters on devices and ports. devlink health show pci/0000:00:09.0/1 reporter tx List status and configuration of tx reporter registered on port on pci/0000:00:09.0/1 devlink health recover pci/0000:00:09.0 reporter fw_fatal Initiate recovery on fw_fatal reporter registered on device on pci/0000:00:09.0. devlink health recover pci/0000:00:09.0/1 reporter tx Initiate recovery on tx reporter registered on port on pci/0000:00:09.0/1. devlink health diagnose pci/0000:00:09.0 reporter fw List diagnostics data on the specified device and reporter. devlink health dump show pci/0000:00:09.0/1 reporter tx Display the last saved dump on the specified port and reporter. devlink health dump clear pci/0000:00:09.0/1 reporter tx Delete saved dump on the specified port and reporter. devlink health set pci/0000:00:09.0 reporter fw_fatal grace_period 3500 Set time interval between auto recoveries to minimum of 3500 msec on the specified device and reporter. devlink health set pci/0000:00:09.0/1 reporter tx grace_period 3500 Set time interval between auto recoveries to minimum of 3500 msec on the specified port and reporter. devlink health set pci/0000:00:09.0 reporter fw_fatal auto_recover false Turn off auto recovery on the specified device and reporter. ## SEE ALSO [**devlink**(8)](https://www.chedong.com/phpMan.php/man/devlink/8/markdown), [**devlink-dev**(8)](https://www.chedong.com/phpMan.php/man/devlink-dev/8/markdown), [**devlink-port**(8)](https://www.chedong.com/phpMan.php/man/devlink-port/8/markdown), [**devlink-param**(8)](https://www.chedong.com/phpMan.php/man/devlink-param/8/markdown), [**devlink-region**(8)](https://www.chedong.com/phpMan.php/man/devlink-region/8/markdown), ## AUTHOR Aya Levin <> iproute2 20 Feb 2019 [DEVLINK-HEALTH(8)](https://www.chedong.com/phpMan.php/man/DEVLINK-HEALTH/8/markdown)
