A system includes a goal state repository, a goal state repository instance and management tools. The goal state repository stores goals for a managed system. The goal state repository instance stores a subset of the goals applicable to a current state of the managed system. The goal state repository instance is created by comparing the current state of the managed system to the goals stored in the goal state repository. The management tools modify the managed system to be in compliance with the subset of goals stored in the goal state repository instance.

In one embodiment, a method includes determining an instrumentation action to perform with the software program when a logging statement is encountered during execution of a software program. The instrumentation action is performed by an instrumentation service associated with a logging service and the execution of the software program is monitored based on the instrumentation action being performed.

Load demands in a power system are managed by determining whether load demands on one or more power system components need to be varied. If the load demands need to be varied, new load demands to be placed on the power system components are determined. The load demands on the power system components are controlled such that the load demands are substantially equal to the new load demands.

A method for restarting a virtual machine in a virtual computing system having a plurality of hosts and a resource scheduler for the plurality of hosts includes writing a placement request for the virtual machine to a shared channel that is accessible by the resource scheduler. The method further includes reading a placement result from the shared channel, wherein the placement result is generated by the resource scheduler responsive to the placement request; and restarting the virtual machine in accordance with the placement result.

In one embodiment, a method for placing virtual machines in a collection is provided. A plurality of equivalence sets of compatible hosts is determined prior to placing virtual machines in the collection. The hosts in an equivalence set of hosts are considered similar. An equivalence set of hosts in the plurality of equivalence sets is selected to place the virtual machines in the collection. The method then places at least a portion of the virtual machines in the collection on one or more hosts in the selected equivalence set of hosts.

Embodiments maintain high availability of software application instances in a fault domain. Subordinate hosts are monitored by a master host. The subordinate hosts publish heartbeats via a network and datastores. Based at least in part on the published heartbeats, the master host determines the status of each subordinate host, distinguishing between subordinate hosts that are entirely inoperative and subordinate hosts that are operative but partitioned (e.g., unreachable via the network). The master host may restart software application instances, such as virtual machines, that are executed by inoperative subordinate hosts or that cease executing on partitioned subordinate hosts.

A computer system for maximizing system and individual job throughput includes a number of computer hardware processor cores that differ amongst themselves in at least in their respective resource requirements and processing capabilities. A monitor gathers performance metric information from each of the computer hardware processor cores that are specific to a particular run of application software then executing. Based on these metrics, a workload assignment mechanism assigns jobs to processor cores in order to maximize overall system throughput and the throughput of individual jobs.

According to one embodiment, a method comprises providing a machine-readable meta-model that defines the structure of how information is represented in at least one data model. The method further comprises using, by a data accessor, the meta-model for interpreting the at least one data model. According to another embodiment, a method comprises providing a machine-readable metric meta-model that defines a syntax for defining metric models, and defining a metric model in the syntax defined by the metric meta-model. The method further comprises associating the metric model with a monitoring source in a monitoring environment, wherein the metric model defines monitoring data available at the monitoring source, and interpreting, by a monitoring tool, the metric model based on the metric meta-model.
摘要:
A system for managing inventory of components in a room. The system includes an identification device configured to communicate identification information relating to an associated component, a reader device configured to substantially autonomously receive the identification information from the identification device, and means for identifying the locations of the identification devices. The system also includes a controller configured to communicate with the reader device and compile the identification information received from the reader device and the locations of the identification devices to maintain an inventory of the components.
