Described are aspects of a sharded monitoring system that collects metrics data from a plurality of targets within a monitored system. The monitoring system includes multiple monitoring-server instances each collecting metrics data from a respective subset of the targets, as well as a federation server that collects aggregated metrics data from the other monitoring-server instances. Mappings between monitoring targets and monitoring-server instances collecting their metrics data may be stored in a temporal routing map, e.g., on the federation server, which may build the map based on time-series routing metrics received from the other monitoring-server instances. The routing map may be used to direct queries for metrics data from a client to the appropriate monitoring-server instance.

Time-series data monitoring with sharded server

Described are aspects of a sharded monitoring system that collects metrics data from a plurality of targets within a monitored system. In various embodiments, the monitoring system includes multiple monitoring-server instances each collecting metrics data from a respective subset of the targets, as well as a federation server that collects aggregated metrics data from the other monitoring-server instances. Mappings between monitoring targets and monitoring-server instances collecting their metrics data may be stored in a temporal routing map, e.g., on the federation server, which may build the map, in accordance with some embodiments, based on time-series routing metrics received from the other monitoring-serve instances. The routing map may be used to direct queries for metrics data from a client to the appropriate monitoring-server instance. Further aspects and embodiments are disclosed.

Systems and methods of stream technologies are disclosed. In some example embodiments, a method and system for a database stream switchover from one data center to another with notification at each component is provided.

Systems and methods of streaming data

In various embodiments of the present invention, tiered command-propagation methods are employed within client computers to ensure that monitoring-and-management-related commands are reliably propagated from server computers to client computers. When possible, command propagation is initiated by server computers through a notification process. When the notification process is inoperable, client computers poll one or more monitoring-and-management server computer for commands. When a failed or interrupted notification process is subsequently restored to operability, client computers automatically discontinue command polling and resume relying on server notification for command propagation.
