 The first four counters should sum to 100 percent. The last three counters also sum to 100 percent. These three counters subdivide the sum of `PercentProcessorTime`, `PercentIOWaitTime`, and `PercentInterruptTime`.

 ### builtin metrics for the File system class
 
 The File system class of metrics provides information about file system usage. Absolute and percentage values are reported as they would be displayed to an ordinary user (not root).
