The electronic device (20) is used for monitoring at least one avionics software application (14) capable of being executed on a platform hosting an operating system (18) offering services, comprises: a module for acquiring respective values of first (23) and second (24) counters of calls sent by the monitored software application (14) to one or more services of the operating system, the first counter (23) being incremented on each successful call (25) and the second counter (24) being incremented on each failed call (26); a module for comparing the respective values of the first (23) and second (24) counters with respective first and second thresholds; and a module for generating an alert signal in the event of detection of abnormal behavior of the software application (14), corresponding to the first counter (23) below the first threshold during a predefined period and/or the second counter (24) greater than the second threshold.
电子设备(20)用于监控能在托管提供服务的操作系统(18)的平台上执行的至少一个航空电子软件应用(14),包括:用于获取由被监控的软件应用(14)向操作系统的一个或多个服务发送的调用的第一计数器(23)和第二计数器(24)的相应值的模块,第一计数器(23)在每次成功调用(25)时递增,并且第二计数器(24)在每次失败调用(26)时递增;用于将第一计数器(23)和第二计数器(24)的相应值与相应的第一阈值和第二阈值进行比较的模块;以及用于在检测到软件应用(14)的异常行为的情况下生成警告信号的模块,异常行为对应于第一计数器(23)在预定时段期间小于第一阈值和/或第二计数器(24)大于第二阈值。
