5.4.3View Power Strip Graphs

Power strip data may be viewed in graphic format, similar to those of sensor data. To access the Power Strip Graphs window (see 5.4.1 - Control Receptacles for more details):

•Click on the Power tab at the top of the Web interface.

•Select a port from the left side of the window by clicking on the name of the port.

•In the right side of the Power Data window, click on one of the blue links—Power, Voltage, Cur- rent or Temperature.

•On the right side of the window, click on the Graph button. The right side of the window shows a graph of current sensor data, upper and lower limits, as in the following example.

The line graph shows the selected sensor’s readings (black) chronologically from left to right—the most current reading is on the far right—as well as Warning (yellow) and Critical (red) limits.

•Use the All or Limit button to change the scale of the y-axis on the graph, as follows:

•Click Limit to use the High and Low Critical values to determine the upper and lower bound- aries of the graph. In the example above, the y-axis extends from 60° to 85°, which are the Low Critical and High Critical values for the Port 1 Temperature Sensor.

•Click All to include the sensor data readings to determine the upper and lower limits of the graph. In the example above, if a data reading were 95°, the y-axis scale would extend from 60° to 95° to include that reading. (If all sensor data readings fall within the High and Low Critical limits, the All and Limit buttons display the same scale extending from the Low Crit- ical value to the High Critical value.)

•Use click-and-drag to zoom in or out:

•To zoom in on an area of the graph, click and drag the mouse downward to draw a box around the area. The maximum zoom level shows 10 units on the y-axis (degrees, for example) and six data samples on the x-axis.

•To zoom out, click and drag the mouse in an upward direction. (Or click on All or Limit to restore the graph to full view.)

•Click the Refresh button to update the graph with the most recent sensor reading. The sensor is sampled at regular inter- vals. See 5.7.3 - Data Presentation to change this interval.

•Click Close to exit the graph window and return to the Power Configuration window.
