Abstract: Model-based system monitoring includes identifying multiple monitors configured to monitor multiple components in a system, and accessing multiple health models associated with the multiple monitors. A monitoring policy is generated to monitor the system. The monitoring policy is derived, at least in part, from the multiple health models.

Abstract: Model-based system monitoring includes accessing a model of a system that includes multiple components and executing a monitoring policy to monitor performance of the system. A notification of a problem is received from a first component. A determination is made regarding the cause of the problem. The determination is made, at least in part, based on the model of the system. At least one component associated with the cause of the problem is then identified.

Abstract: Model-based system monitoring includes accessing a model of a system that includes multiple components and identifying relationships among the multiple components based on the model of the system. A proposed change to at least one of the multiple components is identified. A determination is made regarding an expected impact on the system caused by the proposed change. This determination is made, at least in part, based on the model of the system.

Abstract: Systems and methods are described that monitor health of actively executing computer applications, and particularly which monitor relational database space availability. In one implementation, a warning threshold is defined for free space within a database located on a SQL server. The complexity of the database is assessed, in part by locating each file within the database. A health state is then established for each of the files located within the database, wherein the health state is based on a comparison of free space in each of the located files to the warning threshold.

Abstract: A model of a system is generated and used as a basis for managing the system. As the system is managed, the system model can be updated to reflect changes to the system. Managing of the system can include one or more of provisioning applications in the system, provisioning applications in virtual systems, provisioning test environments, monitoring the configuration of the system, monitoring the system including the health of the system, performing capacity planning for the system, and propagating attributes to different components in the system.
