Description

We are getting results that we should add some diagnostic information to be monitored into system_monitor based on safety analysis made by TIER IV.

Purpose

This is an approach to ensure more system stability and enables developer/operator to get more chance to detect or predict a hazardous event.
Here is current diagnostic information to be monitored by system_monitor.

Possible approaches

Add new diagnostic information to be monitored as follows. (new items are written in red)

Hardware	Potential Failure Mode	Potential Failure Effect	Potential Causes	Action Recommended	New diagnostic Information to be added
Storage	Read/Write error, Read/Write delay, Corruption of recorded data	Data loss, Read/Write delay	Soft error(Transient fault)	Observe a CRC error on the storage	Recovered Error
			High load on communication bandwidth	Observe Read data rate	Read Data Rate
				Observe Write data rate	Write Data Rate
				Observe input/output per second for read	Read IOPS
				Observe input/output per second for write	Write IOPS
LAN	Error in transferred data	Communication failure with sensors/ECUs	Noise on the line	Observe a CRC error on the network interface	CRC Error
GPU	Wrong GPU instructions, processing delays, hungup	Unintended behavior in 3D object detection	Input clock error	Observe if GPU clock is correct	Frequency

HDD Connection

In addition, we will improve hdd_monitor functionality to add diagnostic information on HDD connection.

• The current implementation generates Error when a device is not connected in addition to limit exceeded, so the cause of a error is mixed.
• This will allow us to understand a error is happening due to limit exceeded.

Definition of done

Newly added diagnostic information are correctly reported based on system resource status.
