Constant SYSTEM_DISK_OPERATION_TIME 

pub const SYSTEM_DISK_OPERATION_TIME: &'static str;

Description

Sum of the time each operation took to complete

Notes

Because it is the sum of time each request took, parallel-issued requests each contribute to make the count grow. Measured as:

• Linux: Fields 7 & 11 from procfs-diskstats
• Windows: “Avg. Disk sec/Read” perf counter multiplied by “Disk Reads/sec” perf counter (similar for Writes)
