Thanks mate for coming up with the query on AIX Performance Monitoring.
Here are few to performance monitoring:
Performance monitored for CPU, Memory, Disk, Network and Virtual Memory.
CPU:
# topas, sar , vmstat : Command to monitor the CPU performance.
The value of "usr+sys" cannot be more than 80%.
Memory:
# sar -m, vmstat, svmon, topas: Command to monitor Memory Peformance.
The value of "avm" and "free" to be noted.
Disk:
# iostat : Command to monitor Disk.
%busy and %tps: Should not be high.
