Current state and statistics about how throttled are the block devices when accessed from the controller’s control group.

Fields

io_service_bytes: Vec<IoService>

Statistics about the bytes transferred between the block devices by the tasks in this control group.

io_service_bytes_total: u64

Total amount of bytes transferred to and from the block devices.

io_service_bytes_recursive: Vec<IoService>

Same as io_service_bytes, but contains all descendant control groups.

io_service_bytes_recursive_total: u64

Total amount of bytes transferred to and from the block devices, including all descendant control groups.

io_serviced: Vec<IoService>

The number of I/O operations performed on the devices as seen by the throttling policy.

io_serviced_total: u64

The total number of I/O operations performed on the devices as seen by the throttling policy.

io_serviced_recursive: Vec<IoService>

Same as io_serviced, but contains all descendant control groups.

io_serviced_recursive_total: u64

Same as io_serviced, but contains all descendant control groups and contains only the total amount.

read_bps_device: Vec<BlkIoData>

The upper limit of bytes per second rate of read operation on the block devices by the control group’s tasks.

read_iops_device: Vec<BlkIoData>

The upper limit of I/O operation per second, when said operation is a read operation.

write_bps_device: Vec<BlkIoData>

The upper limit of bytes per second rate of write operation on the block devices by the control group’s tasks.

write_iops_device: Vec<BlkIoData>

The upper limit of I/O operation per second, when said operation is a write operation.
