A system for monitoring provisioned data stores, comprising: a processor; and a memory device including instructions that, upon being executed by the processor, cause the system to: allocate one or more monitoring components of a plurality of monitoring components to each data zone of a plurality of data zones; assign, for each data zone of the plurality of data zones, a plurality of event processors of each monitoring component, allocated to the data zone, to one or more respective data stores associated with the data zone; determine whether a respective heartbeat message is received from each of the other event processors at individual ones of the event processors of the monitoring component allocated to one of the data zones; based on a determination at one or more of the event processors that one of the other event processors failed to send the respective heartbeat message, determine whether the one other event processor failed to send the respective heartbeat message within a specified heartbeat failure time at the one or more event processors; and based on the determination that the one other event processor failed to send the respective heartbeat message within the specified heartbeat failure time, reassign the one or more data stores assigned to the one other event processor amongst the one or more event processors. a processor; and a memory device including instructions that, upon being executed by the processor, cause the system to: allocate one or more monitoring components of a plurality of monitoring components to each data zone of a plurality of data zones; assign, for each data zone of the plurality of data zones, a plurality of event processors of each monitoring component, allocated to the data zone, to one or more respective data stores associated with the data zone; determine whether a respective heartbeat message is received from each of the other event processors at individual ones of the event processors of the monitoring component allocated to one of the data zones; based on a determination at one or more of the event processors that one of the other event processors failed to send the respective heartbeat message, determine whether the one other event processor failed to send the respective heartbeat message within a specified heartbeat failure time at the one or more event processors; and based on the determination that the one other event processor failed to send the respective heartbeat message within the specified heartbeat failure time, reassign the one or more data stores assigned to the one other event processor amongst the one or more event processors. allocate one or more monitoring components of a plurality of monitoring components to each data zone of a plurality of data zones; assign, for each data zone of the plurality of data zones, a plurality of event processors of each monitoring component, allocated to the data zone, to one or more respective data stores associated with the data zone; determine whether a respective heartbeat message is received from each of the other event processors at individual ones of the event processors of the monitoring component allocated to one of the data zones; based on a determination at one or more of the event processors that one of the other event processors failed to send the respective heartbeat message, determine whether the one other event processor failed to send the respective heartbeat message within a specified heartbeat failure time at the one or more event processors; and based on the determination that the one other event processor failed to send the respective heartbeat message within the specified heartbeat failure time, reassign the one or more data stores assigned to the one other event processor amongst the one or more event processors.
