PROBLEM TO BE SOLVED: To provide a failure detection device equipped with functions to detect the failure of a process without performing a ps command or the like several times, and to detect the failure of the process in a real time. SOLUTION: A process ID acquiring means 101 acquires a process list by performing a ps command, and acquires process ID corresponding to a process name mentioned in a monitor target process name description file 15 from the process list. Then, a file describer reading means 102 reads a file descriptor from a process information storage file 13 based on the acquired process ID, and a file descriptor registeration means 103 registers the file descriptor in a file descriptor status detection program 14. Also, a failure detection means 104 detects the failure of a monitor target process by accepting the notification of the invalidation of the file descriptor from the file descriptor status detection program 14.
