I am not getting the data for AIX Disk IO in SSH or Telnet Mode
We
use below command for getting disk IO stats in AIX :
iostat
-d;echo '-----DISK_EXTENDED_STATS-----';iostat -d 1 3 >
/tmp/amp_iostat.txt;sed 's/% tm_act/%tm_act/g' /tmp/amp_iostat.txt
When
you execute iostat -d command you should get output as shown in screenshot.png
attached below. If you get message like "Disk History Since Boot Not
Available" instead of disk statistics, it means it is disabled. To check
current status of iostat--> execute below command in your problematic AIX
servers :
lsattr
-E -l sys0 -a iostat
This
should return output as shown in screenshot2.png attached below. If you get
output like "iostat false Continuously maintain DISK I/O history
True" or "iostat false Continuously maintain DISK I/O history
False", then you need to enable iostat statistics collection. Please refer
following page for doing the same:
