The Observer's setup phase involves initializing essential components like schedulers, loggers, and configurations. Once initialized, the Observer starts its own instance within the game environment, registering its process and thread IDs. This allows for effective monitoring and tracking of its own status, while the core function of the Observer is to continuously monitor game instances and maintain their smooth operation. It operates on a looping mechanism, running at predetermined intervals to regularly assess the status of each game instance.
During each monitoring cycle, the Observer retrieves information on running game instances and cross-references it with the expected active instances. By comparing active process IDs (PIDs), the Observer can identify offline or malfunctioning instances. When an issue is detected, such as an offline instance, the Tera Observer takes appropriate action. It updates the instance's status, notifies the necessary parties, and records relevant error information for prompt resolution.
The primary objective of the Observer is to maintain stability within the game environment. By continually monitoring game instances, detecting inconsistencies, and promptly alerting the appropriate parties, the Observer contributes to seamless gameplay. To efficiently manage monitoring tasks, the Tera Observer relies on a timer and scheduler mechanism. This approach allows the Observer to perform necessary checks, update instance status, and handle errors at regular intervals. By utilizing timers, the Observer maintains continuous monitoring without overwhelming system resources.
