System management is the cornerstone of maintaining high service availability as system administrators must be able to obtain all necessary information about the system's health and operating conditions at any time and configure or reconfigure system parameters. They need to be notified as soon as the system or any of its constituents reaches a state when external intervention is necessary.
Furthermore administrators need to perform root-cause analysis of the different error situation in the system to identify the appropriate remedy and any preventative actions that is necessary to avoid the same situation in the future.
In short high-availability systems must include services that provide an adequate management infrastructure.
In the SA Forum system these services are the Notification, the Log and the Information Model Management services. Each of them deals with a particular aspect of the system operation and maintenance.
This chapter presents these services, their tasks and the solution offered by the SA Forum specifications. It also expands on aspects that are not covered by the specifications, yet important for maintaining a smooth operation of the system thus allowing for higher service availability.
