vmstat has different output format between RHEL5 and RHEL6
Issue
- In RHEL5, we can monitor 'wa' and 'st' value of vmstat by using this command:
[root@rhel570 ~]# vmstat 1 |gawk '/[0-9]$/ {print $1,$2}'
1 0
0 0
0 0
But in RHEL6, we get no output using the same command:
[root@rhel671 ~]# vmstat 1 |gawk '/[0-9]$/ {print $1,$2}'
^C
vmstathas different output format between RHEL5 and RHEL6.
