This video about data center hardware focuses more on hardware, as it is not as obvious as software in some ways. It is important to have hardware that is capable of measuring and presenting data in an appropriate format. Sometimes, this needs to be imported to write the scripts and then convert them into a format that can be graphed.
Some people may think that data is all about working with software and just crunching numbers and a computer. However, the truth is that there is quite a bit of physical work that goes into maintaining a data center and all the hardware that is involved. This is why it is a good idea to learn about both aspects, so that you can understand exactly how the data is processed before it ends up being usable for people. A wireless sensor is one example of the equipment that is used during these processes; it sends the signal to the main receiving station, where the professionals are then able to read the main XML files. An alert is generally sent if a reading is not received in a certain amount of time.
