System information
The System Information section of the Performance Data panel displays system performance data for current and past sessions.
| Type | Type of Job, Master, or Agent System |
|---|---|
| SMFID | The SMFID of each LPAR that each job is running on. |
| ASID | The address space ID for each job. |
| System Number | The relative system number. The Master system is always relative system number 00. |
| Current Interval | The length of time between TDMF polls. |
| Heartbeat | A timer (GMT) that increases for every current interval that the Master or Agent system is active on that specific system. |
| Expires In | The amount of time a system is allowed to be inactive to other systems. |
| Fixed Storage Frames | The number of available fixed storage frames within the LPAR at system initialization that can be dynamically adjusted if pacing is selected. |
| TDMF Fixed Storage Frames | The number of fixed storage frames that TDMF used and is using. |
| TDMF Fixed Storage Thresholds | The high and low watermarks of fixed storage that TDMF uses during the session (obtained at system initialization). These values can change from one session to another. |
| Average RESERVE delay (msecs) | The cumulative amount of time that is spent waiting for SYSCOM Volume Reserve requests divided by the number of READ I/O issued. |
| Average interval READ (msecs) | The cumulative amount of time that is spent waiting for SYSCOM READ I/O to complete divided by the number of READ I/O issued. |
| Average volume loop (msecs) | The cumulative amount of time that is spent processing SRC/TGT volumes between SYSCOM READ and SYSCOM WRITE divided by the number of WRITE I/O issued. |
| Average interval WRITE (msecs) | The cumulative amount of time that is spent waiting for SYSCOM WRITE I/O to complete divided by the number of WRITE I/O issued. |
