System calls summary
The System Calls Summary provides a list of all the system calls that have completed execution on the system during the monitoring period. The list is sorted by the total CPU time in milliseconds consumed by each type of system call.

...(lines omitted)...The System Calls Summary has the following fields:
| Item | Descriptor |
|---|---|
| Count | The number of times that a system call of a certain type (see SVC (Address)) has been called during the monitoring period. |
| Total Time (msec) | The total CPU time that the system spent processing these system calls, expressed in milliseconds. |
| % sys time | The total CPU time that the system spent processing these system calls, expressed as a percentage of the total processing time. |
| Avg Time (msec) | The average CPU time that the system spent processing one system call of this type, expressed in milliseconds. |
| Min Time (msec) | The minimum CPU time that the system needed to process one system call of this type, expressed in milliseconds. |
| Max Time (msec) | The maximum CPU time that the system needed to process one system call of this type, expressed in milliseconds. |
| SVC (Address) | The name of the system call and its kernel address. |
