These columns identify how many times a process became blocked.
For more information about process block counts columns, see ResUsageSpma Table.
| Column Name | Mode | Description | Data Type |
|---|---|---|---|
| ProcBlksCPULimit | count | Number of times processes were blocked by delays due to the Priority Scheduler CPU Limit (for example, System Limit, AG Limit, or RP). For information about the Priority Scheduler CPU Limit, see Utilities. This column is valid on SLES 10 or earlier systems only.
