Constant opentelemetry_semantic_conventions::metric::SYSTEM_DISK_OPERATION_TIME

pub const SYSTEM_DISK_OPERATION_TIME: &str = "system.disk.operation_time";

Description

Sum of the time each operation took to complete.

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)
