    assign, for each data zone of the plurality of data zones, each monitoring component, allocated to the data zone, to one or more respective data stores associated with the data zone;

    determine, for at least one data zone of the plurality of data zones, whether a respective heartbeat message is received from each monitoring component allocated to the at least one data zone, wherein the determination is made by at least one of the monitoring components allocated to the at least one data zone;

    determine, within a specified heartbeat failure time, that a first respective heartbeat message is not received from at least one first monitoring component; and

    reassign at least some of the plurality of monitoring components such that there is at least one second monitoring component reassigned to the one or more data stores previously assigned to the at least one first monitoring component, wherein a second respective heartbeat message was received from the second monitoring component within the specified heartbeat failure time.
