Disaster Recovery and Prevention
Every EAM Agent sends information to the controller about its general health status. Whenever problems occur on an Agent, the controller is notified of the Agent’s status in the form of Agent Events. Problems could include:
- High CPU usage on the Agent
- Large numbers of system errors in a short timeframe
- Unusually high usage of database connections
Loss of connectivity to the Agent also triggers an Agent Event on the controller. Agent Events are recorded in an external database for analysis and reporting later. Agent Events can also be directly configured on the controller to automatically trigger alarms or send alarm notifications.
The Collect Backup Gateway task does more than simply collect a Gateway backup from Agents. Whenever the task runs, the Gateway backup, all installed modules, and the current license are collected from the Agent and stored in the archive system on the controller. This system allows for quick recovery later if an Agent machine catastrophically fails and must be reinstalled.
