Use the Time Range drop-down listbox to modify the time period that the charted information on the Monitoring panel spans.
The graphs on the Monitoring panel display resource usage information:
The Data Space chart displays the amount of allocated data space used by the selected cluster. The red line denotes the threshold specified by the Data Space Threshold slider on the Details panel (the threshold at which the cluster will be scaled-up). The blue line indicates the amount of the data space that is currently in use.
The Connections chart displays a graph of the number of connections to the cluster during the selected time range. The red line denotes the threshold specified by the Connections slider on the Details panel.
The Load chart displays the processing load placed on the CPU by connecting clients. The value displayed is the actual load average as read from the program, /proc/loadavg. The chart shows the number of jobs in the run queue or waiting for disk I/O, averaged over 15 minute periods.
