Abstract
The health of a process is monitored in a computer system by a process monitor. The monitored process (a configuration management system daemon (CMSD)) is not a child of the process monitor. The process monitor uniquely determines the identity of a monitored process and verifies the correct operation of the monitored process. In the absence of verification of the correct operation of the monitored process, the monitored process is caused to initiate. On successful initiation of the monitored process, the monitored process is uniquely identified to the system and is detached from the process monitor. Each monitored process is arranged to write, on initiation, its unique process identification information (PID) to a file, which file is then accessed by the process monitor to identify the process monitor. The process monitor can interrogate the operating system to verify correct operation of the CMSD. As an alternative, the process monitor could test whether the CMSD is functioning by making service requests to the CMSD.
