vmstat' output on AIX looks like:
Code:
root@mickey05:/> vmstat 2

System configuration: lcpu=4 mem=16640MB ent=2.00

kthr    memory              page              faults              cpu

The 2nd row of statistics is interessting, since the 1st is average since boot. So I start in row 7 to check column pi (field 6) and po (field 7) which stand for "paging space in" and "paging space out". It could look like:

Code:
root@mickey05:/> vmstat 2| awk 'NR > 7 {if ( $5 > 10 || $6 > 10) system("myscript.sh")}';

That myscript.sh should handle your mail, might set some locking file so it doesn't spam you every 2 second interval, which vmstat is running on.

Code:
vmstat 2| awk 'NR > 7 {if ( $5 > 10 || $6 > 10) system("myscript.sh")}';

vmstat output goes into awk. awk looks for lines count > 7; then if po or pi (col=$5 $6)
is above 10 execute the script called myscript.sh. myscript sends a warning email.

So, you need to create a simple script to send an email.
