Abstract
Systems and methods of fault detection in a Unix environment. A fault monitor uses process identifiers to access the process control file and status file maintained by the operating system. The fault monitor evaluates process interruptions indicated by the process control signals and selectively communicates information regarding detected interruptions through an event router. The fault monitor uses a fault detection driver that redirects fork requests in order to collect new process identifiers. The fault detection driver modifies the process table associated with the call dispatcher to insert itself between the call dispatcher and the fork routine.
