Abstract

A method and system for monitoring a monitoring-target process. A monitoring-condition registry is searched for a monitoring condition record that controls implementation of the monitoring-target process. The searching includes using a process label as a search key. The process label uniquely identifies the monitoring-target process. It is determined from the searching that the monitoring condition record is stored in the monitoring-condition registry and in response, the monitoring condition record is deleted from the monitoring-condition registry. After the monitoring condition record is deleted from the monitoring-condition registry, a determination is made of the monitoring conditions controlling implementation of the monitoring-target process, after which the monitoring condition record is generated. The generated monitoring condition record includes the determined monitoring conditions. The generated monitoring condition record is stored in the monitoring-condition registry.
