AIX - Performance Monitoring - I/O Bound

AIX - Performance Monitoring - I/O Bound

Using iostat command we can monitor the I/O bound

In this I/O bound we can monitor the disk usage, If you are using two or three heavy used file system in one PV that time that particular PV usage will be very high

AIX - Performance Monitoring - Network Bound

AIX - Performance Monitoring - Network Bound


Using topas command we can monitor the network bound, in this network monitor we can find KB in and KB out process.

AIX - Performance Monitoring - Memory Bound

AIX - Performance Monitoring - Memory Bound

Using vmstart command we can monitor the memory bound

#vmstart 2 3

After this command execution, it will show the memory page in and page out process. Within 2 seconds, 3 outputs is displayed
If you are checking paging space usage using command lsps

#lsps –s

11% - this is normal
40% - Server running on slow performance
70% - users cannot logon the server,
Some error message will appear (fork exist failed)

AIX - Performance Monitoring - CPU Bound

Using Topas command we can check the server performance monitor, the following things we can monitor.

1. processor (CPU Usage)
2. Network (KB in / KB out)
3. Memory (Page in / Page out)
4. I/O (HDD read and write)
5. Top 8 process
