The PUE/DCiE graph shows the calculated PUE/DCiE based on measured data collected on a daily basis according to the configuration done in the ITA desktop client Planning > PUE/DCiE Configuration.
The PUE/DCiE graph shows the calculated PUE/DCiE based on measured data collected on a daily basis. When you add a sensor to the calculations, the data collected from this sensor the previous day, if any, is included in the calculations immediately.
When you add a newly-installed sensor, its value will be included in the calculations once the data collection has run for 24 hours or at least since before the previous midnight.
If you are using PUE as metric, the graph shows the PUE up to 5. If the calculated PUE is greater than 5, the calculated value is displayed and the dial shows the maximum value possible (5).
Note: You can toggle the metric between PUE and DCiE in Tools > Preferences > General.
