System Summary Overview (PI)
Fields
Field name |
Explanation |
---|---|
CPU % |
CPU usage (%). This is also the average value of the percentage for each processor (for AIX, it includes processors after logical partitioning by the Micro-Partitioning function). To display a CPU Usage - Top 10 Processes report, click this field. |
Free Swap % |
Percentage of available swap area size (megabytes) (%). |
Kernel CPU % |
Percentage of operation time in kernel mode (%). This is also the average value of the percentage for each processor (for AIX, it includes processors after logical partitioning by the Micro-Partitioning function). |
Logical I/O Ops |
Number of times logical I/O processing occurred. To display an I/O Activity - Top 10 Processes report, click this field. |
Major Faults/sec |
Frequency of page faults that invoked physical I/O (number of times per second). To display a Major Page Faults - Top 10 Processes report, click this field. |
Minor Faults/sec |
Frequency of page faults that did not invoke physical I/O (number of times per second). |
NFS Client Total Bad Ops |
Total number of times processing failed on the NFS client. |
NFS Server Total Bad Ops |
Total number of times processing failed on the NFS server. |
Physical I/O Ops |
Number of times physical I/O processing occurred. To display an Avg Service Time - Top 10 Devices report, click this field. |
Record Time |
Time when the record was created (Greenwich Mean Time). |
Run Queue |
The number of processes, including processes waiting in the execution queue for the kernel. |
Swapped-In Pages |
Number of pages taken in by swap-in processing. |
Swapped-Out Pages |
Number of pages taken out by swap-out processing. |
Total Page Scans |
Number of pages checked by page scan. |
Total Pkts In |
Total number of IPv4 TCP packets received, IPv4 UDP packets received, and IPv4 ICMP packets received. In 09-00 or later, the total number of packets for IPv4 or IPv6 is displayed. To display a Network Interface Summary report, click this field. |
User CPU % |
Percentage of operation time in user mode (%). This is also the average value of the percentage for each processor (for AIX, it includes processors after logical partitioning by the Micro-Partitioning function). |
Wait % |
Percentage of time in I/O waiting status (%). This is also the average value of the percentage for each processor (for AIX, it includes processors after logical partitioning by the Micro-Partitioning function). |
