The Top Six
There are the most used performance commands on AIX are:| Name | Comments |
| vmstat | Run queue, virtual memory statistics, paging, CPU Utilization and more |
| iostat | Disk and adapters statistics and CPU Utilization |
| netstat | Network statistics (obviously) but hard to use to monitor |
| topas | Excellent online screen and a good summary of everything you need |
| ps | Process list with lots of options and details |
| ??? | What would be your choice for the next tool? |

In Depth Tools
The following AIX performance tools provide in-depth information and metrics related to performance.| Resource | Command |
| CPU Monitoring | netpmon |
| Memory Montiroing | svmon, netpmon, and filemon |
| I/O Subsystem | filemon, fileplace |

Trace based commands
An Event Based Trace Facility collects information about events that occur on the system such as scheduling dispatches, interrupts, and I/O. Trace points are inserted in the kernel code to record the events to a trace buffer. User level tools are provided to view the trace events in a time sequenced fashion. The events can be analyzed to gain a better understanding of the dynamics of the system.| Resource | Command |
| CPU Monitoring | tprof, curt, splat, trace, trcrpt |
| Memory Montiroing | trace, trcrpt |
| I/O Subsystem | trace, trcrpt |
| Network | iptrace, ipreport, trace, trcrpt |
| Processes & Threads | tprof, pprof, trace, trcrpt |
NEW AIX Performance Commands for Micro Partitions
| Name | Comments |
| mpstat | Collects and displays performance statistics for all logical CPUs in the system |
| lparstat | Reports logical partition (LPAR) related information and statistics |
