Hi All,
I would like to create a script that will monitor the server if it's heavy on the processing. I have already some scripts for monitoring disk capacity, application monitoring, etc but not on the bottleneck of the server processing.
I don't know which one to measure/query.
Can you give me some hints?
It's my first time I got bottelneck on the server when I run mksysb and it's year-end with the user.
Thanks in advance,
itik
One more thing, it's the first time also that /system FS have reached 87% and when it goes 90% then I think the system alerted critical state.
There are several places bottlenecks can occur, so I'd start to make a list of things the script should watch in you place:
1) memory - monitor output of "vmstat"
2) processor - monitor output of "vmstat"
3) disk I/O - monitor output of "iostat"
4) network traffic - monitor output "entstat" and compare the increasing numbers
5) swapping - monitor output of "lsps" and/or "vmstat"
I hope this helps.
