Abstract
Tracer systems should not influence running real-time systems such that the real-time demands thereof can no longer be met. In order to resolve this problem, the tracer system disclosed comprises a monitoring means that identifies the dynamic load on a real-time system caused by the tracer system and deactivates the tracer system when the dynamic load upwardly exceeds a specific threshold.
Claims16
In a tracer system for error analysis of programs, said programs running in a real-time system, the improvement comprising:
- a monitor for determining dynamic load on the real-time system caused by the tracer system and for deactivating the tracer system when the dynamic load upwardly exceeds at least one specific threshold.
In a tracer system for error analysis of programs, said programs running in a real-time system, the improvement comprising:
- a monitor for determining dynamic load on the real-time system caused by the tracer system and for deactivating the tracer system when the dynamic load upwardly exceeds at least one specific threshold:
- the monitor having an interface to a system component of the real-time system via which it receives information about an existing overload level in case of overload, and the monitor deactivating the tracer system when a specific overload level has been reached:
- and
- the monitor interface to the system component of the real-time system being to an overload defense system.
In a tracer system for error analysis of programs, said programs running in a real-time system, the improvement comprising:
- a monitor for determining dynamic load on the real-time system caused by the tracer system and for deactivating the tracer system when the dynamic load upwardly exceeds at least one specific threshold:
- the monitor having an interface to a system component of the real-time system via which it receives information about an existing overload level in case of overload, and the monitor deactivating the tracer system when a specific overload level has been reached:
- and
- the monitor permitting the specific overload level to be modified by an operator of the tracer system.

- a monitor for determining dynamic load on the real-time system caused by the tracer system and for deactivating the tracer system when the dynamic load upwardly exceeds at least one specific threshold:
- the monitor having an interface to a system component of the real-time system via which it receives information about an existing overload level in case of overload, and the monitor deactivating the tracer system when a specific overload level has been reached;
- and
- the monitor permitting the specific overload level to be modified by other parts of the system.
In a tracer system for error analysis of programs, said programs running in a real-time system, the improvement comprising:
- a monitor for determining dynamic load on the real-time system caused by the tracer system and for deactivating the tracer system when the dynamic load upwardly exceeds at least one specific threshold:
- and
- wherein the monitor can be unconditionally deactivated by an operator of the tracer system.
