These columns identify the how long the processes were blocked for each possible reason listed.
The following column definition descriptions can also be found in Process Scheduling: Process Pending Wait Time Columns of ResUsageSpma table.
| Column Name | Mode | Description | Data Type |
|---|---|---|---|
| ProcWaitFlowControl | count | Total time in milliseconds processes were blocked pending the delays caused by flow control conditions. | FLOAT |
| ProcWaitFsgLock | count | Total time in milliseconds processes were blocked pending an FSG lock. | FLOAT |
| ProcWaitDBLock | count | Total time in milliseconds processes were blocked pending a database lock. | FLOAT |
| ProcWaitSegLock | count | Total time in milliseconds processes were blocked pending a disk or task context (for example, scratch, stack, and so on) lock. | FLOAT |
| ProcWaitFsgRead | count | Total time in milliseconds processes were blocked pending an FSG read from disk. | FLOAT |
| ProcWaitFsgWrite | count | Total time in milliseconds processes were blocked pending an FSG write from disk. | FLOAT |
| ProcWaitFsgNIOs | count | Total time in milliseconds processes were blocked waiting for task I/Os to complete. | FLOAT |
| ProcWaitMisc | count | Total time in milliseconds processes were blocked pending miscellaneous events. | FLOAT |
| ProcWaitMonitor | count | Total time in milliseconds processes were blocked pending a user monitor. | FLOAT |
| ProcWaitMonResume | count | Total time in milliseconds processes were blocked pending a user monitor resume from a yield. | FLOAT |
| ProcWaitNetThrottle | count | Total time in milliseconds processes were blocked pending delivery of outstanding outgoing messages. | FLOAT |
