1. A networked computer system comprising: a plurality of nodes, each node comprising: at least one processor; and a memory coupled to the at least one processor; a distributed database residing in the memory of the plurality of nodes; a distributed virtual network mechanism that includes a mapping of a plurality of virtual networks to a plurality of physical networks that interconnect the plurality of nodes in the distributed database; and a database performance monitor that monitors performance of the distributed database, identifies a database performance issue for the distributed database, determines from the distributed virtual network mechanism which of the plurality of physical networks are related to the database performance issue, determines a potential solution to the database performance issue that changes configuration of the distributed database, and uses the potential solution by automatically changing configuration of the distributed database without intervention of a user to address the database performance issue, wherein the database performance monitor, after automatically changing configuration of the distributed database, determines whether the changed configuration of the distributed database addressed the database performance issue for the distributed database, wherein, when the database performance monitor determines the changed configuration of the distributed database did not address the database performance issue for the distributed database, the database performance monitor determines whether a second potential solution exists to address the database performance issue, and when the second potential solution exists, the database performance monitor uses the second potential solution by automatically changing configuration of the distributed database without intervention of a user to address the database performance issue, and wherein, when the database performance monitor determines the changed configuration of the distributed database did not address the database performance issue for the distributed database, and when no other potential solution exists to address the database performance issue, the database performance monitor notifies a system administrator that the database performance issue cannot be resolved automatically.
