In some cases you need to install the linux `sensors` package to be able to measure temperature
e.g. on DEBIAN based systems by running `sudo apt-get install lm-sensors`
#### Linux S.M.A.R.T. Status
To be able to detect S.M.A.R.T. status on Linux you need to install `smartmontools`. On DEBIAN based linux distributions you can install it by running `sudo apt-get install smartmontools`
## *: Additional Notes
In `fsStats`, `disksIO` and `networkStats` the `results / sec.` values (rx_sec, IOPS, ...) are calculated correctly beginning
