Claim 10:
11. A monitoring method for monitoring at least one avionics software application capable of being executed on a platform hosting an operating system, the operating system including services, the platform being intended to be carried on board an aircraft,
the monitoring method being implemented by an electronic monitoring device and comprising:
acquire a first value of a first counter and a second value of a second counter for each of the at least one monitored avionics software application, the first counter and the second counter each being a counter of calls sent by the at least one monitored avionics software application to one or more of the services of the operating system, the first counter being incremented upon each successful call to one of the services of the operating system and the second counter being incremented upon each failed call;
compare the first value with a first threshold and the second value with a second threshold; and
generate a warning signal in an event of detection of abnormal behavior of the at least one monitored avionics software application, corresponding to the first value lower than the first threshold during a predefined time period and/or to the second value greater than the second threshold.
