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 |
|---|---|---|---|
| ProcBlksDBLock | count | Number of times processes were blocked for a database lock. | FLOAT |
| ProcBlksFsgLock | count | Number of times processes were blocked for an FSG lock. | FLOAT |
| ProcBlksSegLock | count | Number of times processes were blocked for a disk or task context (for example, scratch, stack, and so on). | FLOAT |
| ProcBlksTime | count | Number of times processes were blocked for a timer expiration. | FLOAT |
| ProcBlksFlowControl | count | Number of times processes were blocked by delays caused by the flow control conditions. | FLOAT |
| ProcBlksFsgNIOs | count | Number of times processes were blocked waiting for task I/Os to complete. | FLOAT |
| ProcBlksFsgRead | count | Number of times processes were blocked for an FSG read. | FLOAT |
