✍️Top AIX UNIX Performance tracking commands every Linux admin/user should know - See more

Though IBM AIX is basically UNIX OS and many of the standard Linux commands are same or similar to AIX's if you happen to be a Linux sysadmin and you've been given some 100 AIX servers, you will have to invest some time to read on AIX, however as a starter you should be aware to at least be able to do performance tracking on the system to prevent system overloads. If that's the case I advise you check thoroughly below commands documentation.

fcstat – Displays statistics gathered by the specified Fibre Channel device driver

filemon – Performance statistics for files, logical/physical volumes and virtual memory segments

fileplace – Displays the placement of file blocks within logical or physical volumes.

entstat – Displays the statistics gathered by the specified Ethernet device driver

iostat – Statistics for ttys, disks and cpu ipcs – Status of interprocess communication facilities

lsps – Statistics about paging space

netstat – Shows network status

netpmon – Performance statistics for CPU usage, network device-driver I/O, socket calls & NFS

nfsstat – Displays information about NFS and RPC calls

pagesize – Displays system page size ps – Display status of current processes

pstat – Statistics about system attributes

sar – System Activity Recorder

svmon – Captures a snapshot of the current contents of both real and virtual memory

traceroute – intended for use in network testing, measurement, and management.

tprof – Detailed profile of CPU usage by an application vmstat – Statistics about virtual memory and cpu/hard disk usage

topas – AIX euqivalent of Linux top command

Here are also useful examples use of above AIX performance tracking commands

To display the statistics for Fiber Channel device driver fcs0, enter:

fcstat fcs0

To monitor the activity at all file system levels and write a verbose report to the fmon.out file, enter:

filemon -v -o fmon.out -O all

To display all information about the placement of a file on its physical volumes, enter:

fileplace -piv data1

To display a continuous disk report at two second intervals for the disk with the logical name disk1, enter the following command:

iostat -d disk1 2

To display extended drive report for all disks, enter the following command:

iostat -D

To list the characteristics of all paging spaces, enter:

lsps -a

List All Ports (both listening and non listening ports)

netstat -a | more

The netpmon command uses the trace facility to obtain a detailed picture of network activity during a time interval.

netpmon -o /tmp/netpmon.log -O all;

netpfmon is very much like AIX Linux equivalent of tcpdump To print all of the supported page size with an alphabetical suffix, enter:

pagesize -af

To display the i-nodes of the system dump saved in the dumpfile core file

pstat -i dumpfile

To report current tty activity for each 2 seconds for the next 40 seconds, enter the following command:

sar -y -r 2 20

To watch system unit for 10 minutes and sort data, enter the following command:

sar -o temp 60 10
