Abstract: Automated computer-implemented methods and systems for monitoring and visually representing attributes of objects executing in a data center are described. Attribute values of the attributes are regularly updated in a database of attributes of the objects for a current time interval. The attribute values obtained in the current time interval are mapped to pixel dimensions of an electronic visual display device. The pixel dimensions correspond to dimensions of features of object icons that represent the objects. The object icons are displayed with the feature dimensions in a graphical user interface (“GUI”) on the electronic visual display device. Each object icon is a visual indicator of a current state of attributes of an object. The collection of object icons displayed reveals at a glance relative differences between attributes of the objects in the current time interval.

Abstract: A plug-in based framework provides high availability (HA), including fault tolerance, in a distributed system, such as provided by a virtualized computing environment. The framework uses blueprints that define entities to be monitored, failure conditions, failover actions, restoration actions, and other aspects associated with HA. Microservices execute the blueprints, and a load balancer may balance the execution of the blueprints amongst microservices.

Abstract: Example techniques for execution of query plans are described. In an example, a query plan may include a first sub-plan and a second sub-plan that are to provide the same output. One among the first sub-plan and the second sub-plan may be selected during execution of the query plan based on a runtime performance parameter of a component to be involved in execution of the first sub-plan and a runtime performance parameter of a component to be involved in execution of the second sub-plan.
