AIX Performance Monitoring - Netpmon
AIX Performance Monitoring - Netpmon
Netpmon
Performance statistics for CPU usage, network device-driver I/O, socket calls, and NFS I/O. For CPU usage, it estimates how much of this usage is due to network-related activities.
Example:
netpmon -o /tmp/netpmon.log -O all

AIX Performance Monitoring Commands
AIX Performance Monitoring Commands
vmstat
The vmstat command reports statistics about kernel threads, virtual memory, disks, traps and CPU activity. Reports generated by the vmstat command can be used to balance system load activity. These system-wide statistics (among all processors) are calculated as averages for values expressed as percentages, and as sums otherwise.
iostat
The iostat command is used for monitoring system input/output device loading by observing the time the physical disks are active in relation to their average transfer rates. The iostat command generates reports that can be used to change system configuration to better balance the input/output load between physical disks and adapters.
netstat
The netstat command symbolically displays the contents of various network-related data structures for active connections. The Interval parameter, specified in seconds, continuously displays information regarding packet traffic on the configured network interfaces. The Interval parameter takes no flags. The System parameter specifies the memory used by the current kernel. Unless you are looking at a dump file, the System parameter should be /unix.
topas
The topas command reports vital statistics about the activity on the local system in a character terminal. It requires the operating system version 4.3.3 or later with the perfagent.tools fileset installed on the system.
The program extracts and displays statistics from the system with a default interval of two seconds. On the operating system version 4.3.3, the output consists on two fixed part and one variable section.
