Constant SYSTEM_DISK_OPERATION_TIME
pub const SYSTEM_DISK_OPERATION_TIME: &'static str;Expand description
§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)
