Abstract

A telematics system can include a processor, installed in a vehicle, ship, or other mode of transport of people, configured to identify an error state of an telematics component providing a telematics service. The processor can also be configured to communicate the error state to a logger component via a logging message. The logger component may be configured to generate a log file based on the logging message.

Claims

1. A system, comprising:

a processing unit;

a logger component;

a telematics component; and

an application component executable by the processing unit to;

provide a service of the telematics component; and

communicate an error state of the application component as a logging message to the logger component, where the logger component is executable by the processing unit to generate a log file based on the logging message, where the processing unit, the logger component, the telematics component, and the application component are configured to be installed in a vehicle, ship, or other mode of transport of people.

2. The system according to claim 1, where the logging message comprises:

a component identifier for the application component;

an error message identifier describing the error state of the application component; and

metadata comprising a parameter.

3. The system according to claim 1, where a memory device is coupled to the processing unit and is configured to store the log file, and where the system further comprises a reporter component executable by the processing unit to communicate the log file to an analyzer component.

4. The system according to one of claim 3, where the reporter component is further configured to communicate the log file to the analyzer component after a predetermined time period.

5. The system according to claim 3, where the analyzer component is executable by the processing unit.

6. The system according to claim 3, where the analyzer component is executable by a processing unit external to the vehicle.

7. The system according to claim 3, where the reporter component is further executable by the processing unit to:

receive data comprising definitions of errors; and

communicate at least the definitions of errors to the application component.

8. The system according to one of claim 7, where the definitions of errors facilitate identification of error states of the application component.

9. The system according to one of claim 3, where the analyzer component is further executable by the processing unit to carry out a fault root cause analysis based on the log file and a predefined use case.

10. The system according to one of claim 2, where the processing unit is configured to:

execute and manage a multi-threaded system adapted to execute concurrent instances of the application component;

carry out a fault root cause analysis based on the log file and a predefined use case, where a state of the predefined use case comprises a use case variable; and

identify an instance of the predefined use case by matching the parameter comprised in the metadata of the logging message to the use case variable.

11. A method, comprising:

identifying, by a processor, a plurality of predefined use cases associated with an application component of a telematics system, where the processor is configured to be installed in a vehicle, ship, or other mode of transport of people;

identifying, by the processor, a logging message from a log file associated with the application component; and

identifying, by the processor, a predefined use case from the plurality of predefined use cases by matching the logging message to an error state of the predefined use case.

12. The method according to claim 11, where the predefined use case includes a plurality of states and relationships provided in a state flow diagram.

13. The method according to claim 11, further comprising:

managing, by the processor, a multi-threaded system executing concurrent instances of the application component;

carrying out, by the processor, a fault root cause analysis based on the log file and the predefined use case, where a state of the predefined use case comprises a use case variable; and

identifying, by the processor, an instance of the predefined use case by matching a parameter comprised in metadata of the logging message to the use case variable.

14. The method according to claim 13, further comprising communicating, by the application component, an error state of the application component to a logger component upon reception of a predefined trigger signal, the predefined trigger signal communicated from the logger component.

15. A method, comprising:

identifying, by a processor configured to be installed in a vehicle, ship, or other mode of transport of people, an error state of an telematics component providing a telematics service;

communicating, by the processor, the error state to a logger component via a logging message; and

generating, by the logger component, a log file based on the logging message.

16. The method according to claim 15, where the logging message comprises:

an identifier associated with the telematics component;

a message identifier associated with the logging message; and

metadata comprising a parameter and a timestamp.

17. The method according to claim 15, further comprising:

communicating, by the processor, the log file to an analyzer component; and

carrying out, by the analyzer component, an automatic fault root cause analysis by analyzing the log file based on a predefined use case.

18. The method according to claim 15, further comprising:

identifying, by the processor, a logging message from the log file; and

identifying, by the processor, a predefined use case from a plurality of predefined use cases by matching the logging message to an error state in the predefined use case,

where the predefined use case is defined as a plurality of states and relationships organized in a graph data structure.

19. The method according to claim 18, further comprising analyzing, by the processor, the predefined use case.

20. The method according to claim 19, further comprising displaying the analysis of the predefined use case by a display device installed the vehicle, ship, or other mode of transport of people.
