Need some help for AIX performance monitoring
Hello
I am new user of AIX; I have only basic knowledge of the UNIX commands, and I want to create script that will monitor the performance and resources usage on AIX 6.1 machine.
Basically I wan to start a loop that will grab, every 10 seconds, the CPU usage, the memory usage, the disk usage, and the Network usage (especially the number of TCP connections that are not completely closed). And create an HTTP POST with all those information to send it to another machine on the same network.
I started the script after looking in some example in the internet, but I ma not sure if what I did until now is correct. Any help or ideas are welcome.
Thank you

can any one tell me, is there is any way i can check the performance of my solaris 8 os on an Ent 3500. Other than top to check for the top most processes, how to make the calculations with vmstat, iostat, mpstat and nfsstat. Or is there any other tools that i can use?
cheers. (3 Replies)

Hi All
I am looking for a script that would collect statistics in a summarised format.
CPU, Memory,Swap, Wait queue, Run queue and disk activity.
Something that would allow me to profile the environment based on a 1 line output that I could run every 15 min.
Thx
