IO - Metrics (Monitoring|Measurement)

IO Wait

IO wait is the percentage of time that the CPU waits for the IO request.

Example via Linux - Top Command:

IOPS

IOPS is the number of IO request per second also known as:

• Disk Transfer (On Windows)
• IO (IO Read, IO Write, IO Others)

See: IO - IOPS (Input/Output Operations Per Second)

From process explorer

• I/O Delta - The change in I/O operations (request ?) since the last measurement
• I/O Delta Bytes - The change in I/O Request by bytes since the last measurement.
• I/O Other - The number of input/output operations generated by a process that are neither reads nor writes, including file, network, and device I/Os. An example of this type of operation would be a control function. I/O Others directed to CONSOLE (console input object) handles are not counted.
• I/O Other Bytes - The number of bytes transferred in input/output operations generated by a process that are neither reads nor writes, including file, network, and device I/Os. An example of this type of operation would be a control function. I/O Other Bytes directed to CONSOLE (console input object) handles are not counted.
• I/O Read Bytes - The number of bytes read in input/output operations generated by a process, including file, network, and device I/Os. I/O Read Bytes directed to CONSOLE (console input object) handles are not counted.
• I/O Reads - The number of read input/output operations generated by a process, including file, network, and device I/Os. I/O Reads directed to CONSOLE (console input object) handles are not counted.
• I/O Write Bytes - The number of bytes written in input/output operations generated by a process, including file, network, and device I/Os. I/O Write Bytes directed to CONSOLE (console input object) handles are not counted.
• I/O Writes - The number of write input/output operations generated by a process, including file, network, and device I/Os. I/O Writes directed to CONSOLE (console input object) handles are not counted.
