Specification of Health Monitoring, AUTOSAR R22-11, FO, No.850

AUTOSARは、ISO、IEC、ITUと情報交換契約を結んでいません。
AUTOSAR文書には、ISO、IEC,ITU記述を全文引用することはできません。
WTO/TBT協定に基づき、国際的な調達は国際規格との差異を記述することにより文化依存しない仕様を目指します。
ISO、IEC、ITU文書を合わせて読むと技術内容は理解できます。　
CAN、OSEK/VDX OS、DIAGは、ISO定義を先に確認しましょう。　　
OSEK COM、OSEK NMなどはISOの規定から基本的な部分で定義を変えています。
変更している部分を仕様等で明記するか、ISOを改定するとよいでしょう。　

AUTOSARの参考文献欄の改定が進んでいません。　
Glossary用語定義の網羅性が低いです。
本文を読む前に確認するとよいかもしれません。
本文を読んでから確認してもよいかもしれません。

• Introduced Elementary Supervision Status for Adaptive platform
• Determination of Supervision Status is now platform specific

用語(terms)

Term	Description
Alive Indication	An indication of a Supervised Entity to signal its aliveness by calling a checkpoint used for Alive Supervision.
Alive Supervision	Kind of supervision that checks if a Supervised Entity executed in a correct frequency.
Checkpoint	A point in the control flow of a Supervised Entity where the activity is reported.
Deadline Supervision	Kind of supervision that checks if the execution time between two Checkpoints is within minimum/maximum time limit.
Final Checkpoint	The ending Checkpoint of a Graph. There can be zero or more Final Checkpoints for each Graph.
Global Supervision Status	Status that summarizes the Local Supervision Status of all Supervised Entities of a software subsystem.
Graph	A set of Checkpoints connected through Transitions, where at
least one of Checkpoints is an Initial Checkpoint. There is a path (through Transitions) between any two Checkpoints of the Graph.
Health Channel	Channel providing information about the health status of a (sub)system. This might be the Global Supervision Status of an application, the result any test routine or the status reported by a (sub)system (e.g. voltage monitoring, OS kernel, ECU status, ...).
Health Channel Supervision	Kind of supervision that checks if the health indicators registered by the supervised software are within the tolerances/limits.
Health Monitoring	Supervision of the software behaviour for correct timing and sequence.
Health Status	A set of states that are relevant to the supervised software (e.g. a Voltage State, an application state, the result of a RAM monitoring algorithm).
Health Status Supervision	Check if the health indicators registered by the supervised software are within the tolerances/limits.
Initial Checkpoint	The starting Checkpoint of a Graph. There can be one or more Initial Checkpoints for each Graph.
Logical Supervision	Kind of online supervision of software that checks if the software (Supervised Entity or set of Supervised Entities) is executed in the sequence defined by the programmer (by the developed code).
Local Supervision Status	Status that represents the current result of Alive Supervision, Deadline Supervision and Logical Supervision of a single Supervised Entity.
Machine	see [3] AUTOSAR Glossary
Platform Health Management	Health Monitoring for the Adaptive Platform
Supervised Entity	A whole or part of a software component type which is included in the supervision. A Supervised Entity denotes a collection of Checkpoints within the corresponding software component type. A software component type can include zero, one or more Supervised Entities. A Supervised Entity may be instantiated multiple times, in which case each instance is independently supervised.
Supervision Mode	An overall state of a microcontroller or virtual machine or state of a Function Group (in case of Adaptive Platform). Modes are mutually exclusive. A mode can be e.g. Startup, Shutdown, Low power.
Health Indicator	Health Indicator provides an evaluation metric of current system performance with regard to safety requirements.
System Health Monitor(SHM)	System Health Monitor is responsible for monitoring the health of a (Sub)-system. It provides Health Indicators that can be used for system wide error handling across several Classic, Adaptive and any third party platforms.
Local Health Monitor	Local Health Monitor gathers health information of the platform on which it is deployed.
Health Indicator Interface	Health Indicator Interface is an interface used for communication of Health Indicators using a standardized service field.
SE	Supervised Entity.
SOTIF	Safety Of The Intended Functionality [4].
Performance	The Performance rates the performance with respect to malfunctioning behavior.
Reliability	Reliability evaluates how much to trust the system due to uncertainties.
