The Input/Output Token Allocations (IOTA) columns provide the percentage of disk throughput that is being used.
| Column Name | Mode | Description | Data Type |
|---|---|---|---|
| FullPotentialIota | count | Sum of the full potential input or output token allocations from all devices attached to the node. The input or output token allocations are not limited by the IO_COD setting. The value is computed by summing the cod_full_potential_iota field for each device in the /proc/tdmeter/disk_cod_stats file. |
FLOAT |
| CodPotentialIota | count | Sum of potential input or output token allocations from all devices attached to the node. The input or output token allocations are accumulated only when an I/O is pending on a device and are limited by the IO_COD setting. The value is computed by summing the cod_allocated_iota field for each device in the /proc/tdmeter/disk_cod_stats file. |
FLOAT |
| UsedIota | count | Sum of used input or output token allocations from all devices attached to the node. The value is computed by summing the cod_used_iota field for each device in the /proc/tdmeter/disk_cod_stats file. |
