Device ManageR will automatically discover any Room Alert or TemPageR devices on the network and regularly log the current sensor values to a database. Using the logged sensor values, Device ManageR allows users to view real-time graphs of sensor data over multiple date and time ranges. This is especially useful for identifying historical trends in power or cooling as well as for identifying potential trouble spots in the data center environment.

To view the real-time sensor data graph, open Device ManageR and select the device you wish to view either from the left menu, or the 'Discovered Devices Summary' section on the right hand side of the screen.

Near the top of the 'Sensor Display' view you will see four tabs for your device, select the 'Graph Display' tab. When you first open the 'Graph Display' tab, it will begin loading the default graph. The default graph will display all of the sensor data from the current day. On the y-axis of the graph (left vertical side) you will see the range of values that are being graphed. On the x-axis of the graph (bottom horizontal side) you will see the time range of the current graph.

Below the graphed data, a date and time range can optionally be selected to determine the period of time that should be displayed in the graph. To change the start date and time for the graphed data, click on the calendar icon next to the 'Start' label. To change the end date and time for the graphed data, click on the calendar icon next to the 'End' label. After selecting the date and time range to display, click on the 'Reload Graph Data' button and Device ManageR will update the graph display to show the sensor data over the new date and time range.

At the bottom of the Graph Display is a 'Graphed Sensors' section that functions as the legend for the graphed data. By default, the temperature values will be selected and displayed on all Digital Temperature and Digital Temp/Humidity Sensors connected to the selected device. The currently displayed sensors are highlighted in blue. To add or remove a value from the graph display, simply click the desired sensor type below the sensor label. The new sensors will automatically be displayed on the graph and the range of values on the y-axis will automatically be updated if necessary to display the new values..
